How to realize 12V on-board power supply for ev

There are many low-voltage electrical equipment on the new energy electric vehicles, such as the dashboard, electric Windows, windshield wipers, lights, multimedia equipment and so on.

These devices can work normally at a low voltage of 12V, 24V or 48V. However, the voltage of electric vehicle power battery is as high as 200V~800V, so how does it achieve low 12V on-board power supply?

As we all know, low-voltage electrical equipment such as dashboards, windows, and wipers on fuel vehicles are powered by 12V low-voltage batteries. Since the capacity of 12V low-voltage batteries is small, it is necessary for the engine to drive a generator to generate electricity to charge the batteries.

However, the low-voltage battery charging is not completed by the generator, but through the vehicle DC/DC converter to convert the high-voltage DC of the power battery into low-voltage DC, to charge the low-voltage battery, as well as the low-voltage electrical equipment for the vehicle power supply.

There is a group of large capacity power battery on the electric vehicle, its electric energy on the one hand used to drive the motor operation, driving the vehicle.

On the other hand, through the DC/DC converter installed in the car, the high voltage direct current is converted into 12V, 24V or 48V low voltage direct current, to the instrument panel, electric Windows, wiper, lights, low voltage battery and other low voltage electrical equipment power supply.

Therefore, on-board DC/DC converter is the core component to realize electric energy conversion on electric vehicles. With the continuous increase in the production and sales of electric vehicles, the sales of on-board DC/DC converter also increase on a large scale.

In our country, DC/DC converter is mainly developed and produced by third-party manufacturers and then provided to electric vehicle vehicle manufacturing plants.

For example, Dillon New Energy is a high-tech enterprise focusing on R&D, production and sales of on-board DC/DC converters, on-board chargers (OBCs) and on-board power integrated products.
