Onboard charger

Delphi onboard charger is an aftermarket solution for plug-in hybrid electric vehicles (PHEV) and battery electric vehicles (BEV) that converts AC to DC in order to charge the traction battery pack.

Since 2015, Delphi offers a wide range of AC/DC onboard chargers in production that support fast charging for plug-in hybrid and battery electric vehicles. We apply the same technological expertise to our aftermarket onboard chargers for exact OE performance.

What is an onboard charger for an electric vehicle?

Unlike internal combustion engines, plug-in hybrid electric vehicles (PHEV) and battery electric vehicles (BEV) use an electric traction motor to drive the vehicle’s wheels. The onboard charger charges the traction battery pack, and the energy stored in the battery is then used to power the electric motor.

When an electric vehicle is plugged into a household outlet or a level 2 charger, the charging cable pulls alternating current (AC) from the power grid and sends it to the onboard charger. In order to store the electric power in the battery, the onboard charger must then convert AC to direct current (DC).

Additionally, the onboard charger monitors voltage, current, temperature, and state of charge while charging for the safety of the electrical system and the driver.

Resource Highlights

We’ll take you through how to use a diagnostic tool to check the health of a vehicle’s battery.

Why do I need to perform a battery health check?

Some manufacturers insist on a battery health check as part of a vehicle’s annual service to maintain the warranty, others to extend it.

How do I plug in the diagnostic tool?

Find the vehicles OBD socket and plug in the Delphi DS180 or DS480 diagnostic tool.

How do I make sure the diagnostic tool is set to the right vehicle?

Enter the vehicles registration or VIN on the diagnostic tool to bring up the diagnostic data on it. Then, go to the EV control module and from here click through to the HV-battery regulation section. You can now connect to the vehicle and perform the diagnostic check.
