A major function of an on-board charger in an electric vehicle
An ev on board charger's primary duty is to control the flow of current from the grid to the traction battery. OBC series on-board chargers allow electric vehicle chargers to charge from any source. As a result, electric vehicles are not always dependent on charging stations.Controlling the amount of current and voltage used to charge the battery is another duty of the onboarding charger. Constant voltage and constant current charging are the two basic forms of charging.
Even while high efficiency and rapid charging are provided by constant current charging, the battery's lifespan may be impacted. This results from excessive billing. There is a potential that a significant quantity of current could flow into the battery during constant voltage charging.
The aforementioned issue can be resolved by initially charging the battery using constant current. The battery is then charged utilizing constant voltage charging after reaching a specified amplitude in which the primary function of an onboard charger is to manage to charge.
