Note for First-Time Users: Este Cargador EV simplifies the charging process, making level 1 charging the most practical method for daily vehicle readiness in Brazil.
Understanding Your Level 1 Charger
The portable charger that accompanies a new electric vehicle is a powerful and convenient tool. Drivers should familiarize themselves with its parts and functions to ensure safe and effective operation. This knowledge empowers owners to handle daily charging with confidence.
What’s in the Bag? The Components Explained
Inside the storage bag, owners will find several key components that work together. Each part of the level 1 EV charger has a specific purpose. A typical kit includes:
- A portable EVSE (Electric Vehicle Supply Equipment) unit
- A standard wall plug for Brazilian outlets
- A control box containing essential safety circuits
- A J1772 connector for the vehicle’s charge port
The Control Box (The “Brain” of the Charger)
The control box is the most critical part of the level 1 charger. It acts as the central processing unit, managing the flow of electricity from the wall outlet to the car. This “brain” communicates with the vehicle to determine the correct charging rate. It also houses multiple safety mechanisms to protect both the user and the vehicle.
The Wall Plug (Connecting to Your Home’s Power)
The wall plug is the component that connects to a standard household outlet (outlet). In Brazil, this plug is typically the three-pin NBR 14136 standard. It draws alternating current (AC) power from the home’s electrical system to begin the charging process. A secure connection to a properly grounded outlet is essential for safety.
The Car Connector (The J1772 Nozzle)
The car connector, often called a nozzle, is the part that plugs into the vehicle. Most non-Tesla EVs in Brazil use the Type 2 connector, which is the European standard. However, some models may use the J1772 standard. This connector establishes a data and power link, allowing the charger and car to communicate.
How Your Portable Charger Works
The portable charger performs two fundamental tasks: converting power and ensuring safety. Understanding this process helps demystify what happens after plugging in.
Consejo profesional: Companies like TPSON engineer their portable EV chargers as advanced charging solutions, integrating sophisticated safety protocols directly into the control box for maximum user protection.
Converting AC Power from Your Outlet to DC for Your Battery
Household outlets supply alternating current (AC). However, an EV’s battery stores energy as direct current (DC). The vehicle’s onboard charger, not the portable cable, performs this conversion. The portable charger’s job is to safely deliver the AC power to the car, which then converts it to DC to replenish the battery.
The Safety Functions of the Control Box
The control box is a guardian of the charging session. It continuously monitors for potential issues. Key safety functions include protection against over-voltage, under-voltage, overheating, and current leakage. If the box detects a fault, it will immediately stop the flow of electricity to prevent damage to the car’s battery or a potential electrical hazard.
A 4-Step Guide to Using Your Level 1 Charger
Using the portable level 1 charger is a simple process. This guide breaks it down into four manageable steps, ensuring a safe and successful charge every time. Following this sequence is essential for protecting both the vehicle and the home’s electrical system. This is not a complex step-by-step installation guide, but a simple routine for daily use.
Step 1: Check Your Outlet (Tomada)
Before plugging anything in, the driver must inspect the wall outlet. The condition of the outlet is the most critical factor for safe home charging. A proper connection begins with a suitable and safe power source.
Identifying a Grounded Three-Prong Outlet
A driver must use a modern, three-prong outlet that complies with the Brazilian NBR 14136 standard. The third, central pin is the ground connection, and it is not optional. Using an ungrounded two-prong outlet, even with an adapter, introduces serious dangers.
Alerta de seguridad: An ungrounded outlet creates significant risks. Without a ground connection, stray electrical currents have no safe path to the earth, leading to severe consequences:
- Electric Shock Hazards: Faulty equipment can energize the charger’s metal parts or the car’s chassis, creating a severe shock risk for anyone who touches them.
- Equipment Damage: The level 1 EV charger and the vehicle’s onboard systems are sensitive to voltage spikes. An ungrounded connection can cause component burnout and premature failure.
- Potential for Electrical Fires: Stray currents can cause wiring to overheat or arc, which can easily ignite nearby materials and start a fire.
The Difference Between 110V and 220V for Charging
In Brazil, homes have either 110V (or 127V) or 220V outlets. Both can power a portable charger, but they deliver very different charging speeds. A 220V outlet will charge the vehicle’s battery approximately twice as fast as a 110V outlet. For overnight charging, either voltage is often sufficient, but 220V provides more flexibility and a faster recovery.
Why a Dedicated Circuit is Best Practice
For optimal safety and performance, the outlet used for charging should be on a dedicated circuit. This means a single circuit breaker in the electrical panel serves only that one outlet. This practice prevents overloads that occur when the charger shares a circuit with other high-power appliances, like an air conditioner or microwave. A dedicated circuit ensures the charger receives consistent power without tripping the breaker. A professional can assist with this installation.
Step 2: Plug the Charger into the Wall First
The sequence of connections is important. The charger must be connected to the power source before it is connected to the vehicle.
The Correct Sequence: Wall First, Then Car
The correct procedure is to plug the charger’s wall plug firmly into the grounded outlet first. Wait a few seconds before proceeding. This allows the control box to perform a self-test. It verifies the power source is stable and properly grounded before it signals that it is ready to deliver power to the car. This handshake protects the vehicle’s sensitive electronics.
Checking the Indicator Lights on the Control Box
After plugging the charger into the wall, the driver should look at the indicator lights on the control box. Most units will display a solid green light to indicate that the power is on and the unit has passed its safety checks. If a red or flashing light appears, first-time users should unplug the charger and consult the owner’s manual. This often indicates a problem with the wall outlet’s grounding or power supply.
Consejo profesional: Advanced portable chargers, like those engineered by TPSON, feature clear and intuitive status lights. These indicators provide immediate feedback on power, charging status, and any potential faults, simplifying the process for the user.
Step 3: Connect the Charger to Your Car
With the charger powered on and ready, the final step is to connect it to the vehicle.
How to Open Your Car’s Charging Port
The method for opening the charge port door varies by vehicle model. Common methods include pressing a button inside the cabin, using a button on the key fob, or simply pressing on the charge port door itself. The vehicle’s owner’s manual provides the exact instructions for a specific model.
Plugging in the J1772 Connector Securely
The driver should align the J1772 connector with the car’s port and push it in firmly. A distinct “click” sound confirms that the connector has latched securely. This mechanical lock is a safety feature that prevents the cable from being accidentally disconnected during a charging session. A secure connection is necessary for the charging process to begin.
Paso 4: Confirmar que se ha iniciado la carga
After connecting the cable, the driver must verify that the vehicle is actively receiving power. Modern electric vehicles provide multiple clear indicators to confirm a successful connection. This final check ensures the car will be ready for the next day’s journey.
Checking for Confirmation on Your Car’s Dashboard
The most immediate confirmation comes from the vehicle’s dashboard or instrument cluster. After plugging in the connector, the driver should get into the car or look through the window at the display.
- Visual Icons: Most EVs will display a specific icon, such as a plug symbol or an animated battery graphic, to show that a charging session is in progress.
- Status Information: The dashboard often provides detailed information. This can include the current battery percentage, the estimated time until the battery is full, and the charging rate in kilowatts (kW).
This dashboard feedback is the primary and most reliable way to know the car is accepting a charge.
Understanding the Lights on the Charging Port
Many electric vehicles have indicator lights located directly around the charging port. These lights offer a quick visual status update without needing to enter the vehicle. The color codes can vary slightly between manufacturers, but they generally follow a common pattern.
Common Light Indicators:
- Solid or Pulsing Blue: The car is connected and communicating with the charger, but charging has not yet started. This may occur if a scheduled charging time is set.
- Solid or Pulsing Green: The vehicle is actively charging. This is the color drivers want to see.
- Solid Red or Orange: A fault has been detected. The driver should unplug the cable from both the car and the wall, then try the connection sequence again. A persistent red light may indicate an issue with the outlet or the charger itself.
First-time users should consult their vehicle’s manual to understand the specific light codes for their model.
Using Your Car’s Mobile App to Monitor Charging
Nearly all modern EVs come with a companion mobile application. This app is a powerful tool for managing the vehicle’s charging from anywhere. After starting a session, the driver can open the app on their smartphone to see real-time data.

- Mando a distancia: Start or stop a charging session remotely. This is useful for taking advantage of off-peak electricity rates.
The mobile app provides peace of mind, allowing the owner to confirm the vehicle is charging correctly without having to go back to the garage.
Essential Safety Rules for Charging in Brazil
Adhering to fundamental safety protocols is non-negotiable for home EV charging. These rules protect the driver, the vehicle, and the home from electrical hazards. Following them ensures every charging session is safe and reliable.
The Golden Rule: Never Use Standard Extension Cords (Extensões)
The most important rule is to never connect the portable charger to a standard household extension cord. These common orange or white cords are not designed for the high, sustained power draw required for EV charging.
Why Household Extension Cords Are a Fire Hazard
A typical extension cord is built for temporary, low-power uses like a lamp or a fan. When used for EV charging, its thin internal wires cannot handle the continuous electrical load. This inadequacy creates a significant risk of the cord melting and igniting, leading to a dangerous fire.
Understanding Overheating and Voltage Drop Risks
Using an improper cord leads to two major problems: overheating and voltage drop. The resistance in thin wires generates excessive heat. Additionally, the voltage can drop significantly over the length of the cord, which reduces charging efficiency and can damage the charger’s control box.
La seguridad ante todo: If an extension is absolutely necessary, a driver must use a heavy-duty cord made specifically for EV charging. These have critical safety features:
- A thick copper core of at least 1.5mm in diameter.
- A durable, weather-proof rubber exterior.
- A current rating of 13A or higher.
- The cord must be fully unrolled during use to dissipate heat correctly.
Protect Your Charger from Rain, Sun, and Heat
Environmental factors in Brazil present unique risks. Drivers must protect their charging equipment from the elements, especially when charging outdoors.
Outdoor Charging: Using a Weatherproof Outlet Cover (Tampa de Proteção)
When using an outdoor outlet, it must have a weatherproof, in-use cover (weatherproof cover). This cover shields the plug and outlet connection from rain, preventing short circuits and electrical shock.
Keeping the Control Box Dry and Out of Puddles
The control box is the brain of the charger. A driver must ensure it remains completely dry. It should be suspended off the ground, away from puddles, sprinklers, or potential water flow.
Avoiding Direct Sunlight to Prevent Overheating
Intense sun is one of the Brazil-specific challenges. While robust chargers are engineered to operate in a wide temperature range, often from -30 °C to +50 °C, direct sunlight can heat the control box beyond its safe limit. A driver should place the control box in a shaded, well-ventilated area to prevent it from overheating and shutting down.
Critical Electrical Safety at Home
A driver’s diligence with electrical safety inside the home is just as important as it is outside.
Why You Must Avoid Adapters and “Benjamins” (T-Connectors)
Drivers must plug the charger directly into a grounded, three-prong outlet. Using adapters to fit older two-prong outlets or using “T-connectors” (T-connectors) to share an outlet is extremely dangerous. These devices create weak connection points that can easily overheat and cause a fire.
How to Inspect Your Charger Cable for Damage Before Each Use
Before every use, a driver should perform a quick visual inspection of the entire charger cable. Look for any signs of wear or damage that could make it unsafe.
Pre-Charge Checklist:
- Cracks or scorch marks on the plug or connector casing.
- Exposed or frayed internal wiring anywhere along the cable.
- Bent or misaligned pins on the connector.
- Any signs of overheating damage, such as melted plastic.
If any damage is found, the driver must not use the equipment and should contact the manufacturer for a replacement.
When to Call an Electrician (Eletricista)
Knowing when to manage home charging independently versus when to hire a professional is key to safety. While the portable charger is a plug-and-play device, the home’s electrical system must be ready for it. This section clarifies when a driver can proceed with confidence and when they must call a qualified electrician in Brazil.
When You Don’t Need an Electrician
In many modern homes, a professional call-out is not necessary. A driver can safely use their Level 1 charger if their home meets two important conditions.
You Already Have a Modern, Grounded Outlet
If the intended charging location already has a modern, three-prong NBR 14136 outlet, the first requirement is met. The driver should confirm the outlet is in good condition, with no cracks, scorch marks, or loose connections. A secure, grounded outlet is the foundation of safe charging.
The Circuit is Not Shared with Other High-Power Appliances
The driver must also verify that the outlet is on a circuit that does not power other heavy-use appliances. Items like electric showers, air conditioners, or microwaves can overload the circuit when used simultaneously with the charger. If the outlet is on a lightly used or dedicated circuit, the driver can typically begin charging without professional assistance.
When You Must Call a Professional
Certain situations make hiring an electrician non-negotiable. Attempting electrical work without proper training is extremely dangerous. A professional ensures the installation is safe, compliant with local codes, and capable of handling the demands of EV charging.

The professional will run the correct wiring from the breaker panel, install a high-quality outlet, and ensure the circuit has the proper capacity. This is the safest and most reliable way to upgrade.
To Upgrade an Old Two-Prong Outlet
If the home has only old, two-prong outlets, the driver must call an electrician. These outlets are ungrounded and unsafe for EV charging. A professional will need to perform an installation of a new, grounded outlet, which may involve running a new ground wire to make the connection safe.
If Your Circuit Breaker (Disjuntor) Trips Repeatedly
A circuit breaker (circuit breaker) that trips is a clear warning sign. While advanced chargers from providers like TPSON have built-in protections, the problem often lies with the home’s wiring. A driver should not ignore this. Common causes include:
- Circuit Overload: Too many devices are drawing power from the same circuit.
- Short Circuit: A live wire has made contact with a neutral wire.
- Ground Fault: A live wire is touching a grounded part of the system.
- Entrada de agua: Moisture has entered the charger or outlet.
A professional can diagnose the root cause and perform the necessary repairs. This is a critical step for a safe home charging installation.
If You Are Unsure About Your Home’s Wiring Quality
For older homes in Brazil, or if a driver has any doubts about the electrical system’s integrity, hiring an electrician for an inspection provides peace of mind. A professional can assess the wiring, the breaker panel, and the outlet’s condition to confirm everything is safe for EV charging. This small investment prevents major risks. A proper installation is paramount.
