 How to choose the suitable battery on board charger? Note： the main function of the battery charger is to convert 220V or 110V AC power into the DC power required by the battery, and then charge the battery. （https://www.researchgate.net/figure/On-board-charger-on-a-BEV_fig1_351506797） When choosing a battery charger, you need to pay attention to the following points: 1. Confirm the battery type First, you need to determine the type of battery and determine the charger parameters according to the brand, type, and model of the battery used. 2. Select the appropriate charging voltage and charging current According to the charging characteristics of the battery, select the appropriate charging voltage and charging current. Charging voltage: Calculate the series voltage of the battery pack and determine the charger voltage. For example, if the battery pack is 5 pcs of 12V batteries and the charging voltage is 12V*5=60V, then a 60V charger is more appropriate. Charging current: The num...

 W hat is on board charger (OBC)? An on-board charger (OBC), also known as an on-board charger, is a charger fixed on an electric vehicle. It can safely and automatically charge the power battery of the electric vehicle. It is mainly used in chargers that must be "plugged in". ” Rechargeable electric vehicles such as battery electric vehicles (BEV, purely battery-powered) and plug-in hybrid electric vehicles (PHEV) As the interface between electric vehicles and the public power grid, OBC can convert the alternating current (AC) from the power grid into the direct current (DC) required by the high-voltage battery of electric vehicles to charge the power battery of the electric vehicle; it can also convert the DC power from the power battery. The inverter converts alternating current back to the grid to realize energy conversion between the car's power battery and the grid. The OBC of new energy vehicles is divided into unidirectional OBC and bidirectional OBC. The circuit ...
