First of all, the on-board charger refers to a charger fixedly installed on an electric vehicle. Its main function is to charge the power battery of the electric vehicle safely, quickly and conveniently. The on-board charger is connected to the AC socket through a plug and a cable, so it can also be called an AC charger.
The advantage of the on-board charger is that it can be charged as long as there is an available power socket when the battery needs to be charged.
The on-board charger generally has 3 interfaces, namely:
1) AC input: Connect the connector coming from the AC charging socket;
2) DC output: The charger and battery connection port
3) Low-voltage control interface:
The low-voltage interface between the on-board charger and the BMS and the outside, usually 12V.
The power battery of electric vehicles, golf carts, forklifts, tricycles, etc. can only accept DC charging. That is to say, if the external connection to the electric vehicle is AC, it is necessary to first use the on-board charger, that is, OBC, to perform AC/DC conversion, that is, AC to DC, and then charge the power battery. If it is DC charging, just connect the power battery directly through the cable in the car to charge.
However, DC charging at a general charging station consumes more time and money. Most people choose to charge at home with household AC current, which is more energy-saving and cost-saving.
Newtop's smart charger can not only match the battery charging curve to protect the battery, but also convert the current. It has good quality and is durable.
Ordinary chargers cannot match the battery charging current, which can easily shorten the battery life, and the life of the charger is mostly short.
