A Off-Board / Portable EV Charger is a compact, lightweight device designed to charge the batteries of electric scooters, motorcycles, and e-rickshaws. These chargers can be used almost anywhere there's access to electricity, offering convenient charging on the go.

An onboard charger (OBC) is a device installed in electric vehicles (EVs) that converts alternating current (AC) from an external power source, such as a residential outlet, into direct current (DC) to charge the vehicle's battery.

Charging Modes: OBCs use two main charging modes: constant current and constant voltage. Constant current charging provides faster charging but can affect battery lifespan, while constant voltage charging is slower but safer for the battery.

Neenjas EV Chargers provide flexibility and convenience, allowing you to charge your electric vehicle at home, work, public charging stations, or while traveling. They serve as a reliable backup charging solution, ensuring you’re never stranded without power.

To choose the right EV Charger, consider the following factors:

• Charging Speed: Determine if you need a standard or fast charger based on your usage and charging time preferences.
• Compatibility: Ensure the charger is compatible with your vehicle’s battery type and specifications.
• Portability: Look for a charger that is easy to carry and store.

Some EV Chargers are versatile and can be used for both two-wheelers and e-rickshaws, while others are specifically designed for one type. Check the charger’s specifications and compatibility before use.

The charging time depends on the battery capacity and the type of charger you are using. Standard chargers may take several hours, while fast chargers can significantly reduce the charging time. Refer to the manufacturer’s guidelines for specific charging durations.

Yes, Our EV Chargers are designed with safety features to ensure they are safe to use. Features may include overcharge protection, short-circuit protection, and thermal management. We recommend to always follow the manufacturer’s instructions for safe operation.

Proper maintenance of your EV Charger includes:

• Regular Cleaning: Keep the charger and its components clean to prevent dust and debris buildup.
• Proper Storage: Store the charger in a cool, dry place when not in use.
• Cable Inspection: Regularly check the charging cables for wear and tear, and get them replaced if necessary.
• Follow Guidelines: Adhere to the manufacturer’s maintenance guidelines to ensure optimal performance.

EV Chargers typically require a standard 220-240V AC outlet for charging. Some fast chargers may require higher voltage or specific power outlets. Check the charger's specifications for exact power requirements.

Charging capacity varies by model. Standard chargers usually offer a power output of 1-2 kW, while fast chargers can provide 2-3.3 kW or higher. Ensure the charger’s output matches your vehicle’s battery capacity for optimal performance.

Yes, Neenjas EV Chargers are designed to be compatible with various battery types, including LMFP, LFP or NMC. Always check the charger’s compatibility with your vehicle's battery type before use.

Neenjas EV Chargers come with several safety features such as:

• Overcharge Protection: Protect the battery from being overcharged.
• Overvoltage Protection: Protect the battery from overvoltage. (Soft-Start feature prevents the initial surge of the voltage.)
• BMS Based Protection: Stops the charging if BMS is in protection mode.
• Short-Circuit Protection: Protects the charger and vehicle from short-circuit damage.
• Reverse Polarity: Protect the battery in case of reverse connection.
• Thermal Management: Manages the temperature to prevent overheating.
• Surge Protection: Protects the charger from power surges and spikes.

Connecting a EV Charger involves the following steps:

• Plug the Charger into an Electrical Outlet: Ensure the charger is connected to a suitable power source.
• Connect the Charger to the Vehicle’s Charging Port: Use the appropriate connector that matches your vehicle’s charging port and connect properly as loose connection can lead to an unexpected behaviour of the charger.
• Follow the Manufacturer's Instructions: Refer to the charger's manual for specific connection guidelines and safety precautions.

The efficiency of Neenjas EV Chargers is more than 90%. Higher efficiency chargers convert more electricity into usable energy, resulting in less energy loss during charging.

While many EV Chargers are designed to be weather-resistant, it’s important to follow the manufacturer’s guidelines for usage in extreme weather conditions such as heavy rain, snow, or excessive heat. Neenjas EV chargers are IP67 rated indicating their level of protection against dust and water & also tested for extreme weather conditions.

Any change or update in the firmware can only be done by Neenjas. Firmware can be update remotely using some specific tools based on the request given by OEMs only.

End user is not allowed to make any change in the firmware.

Neenjas Chargers generally uses CAN based communication protocols to interact with batteries customized as per OEMs request.
