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

In this article you will find a step by step guide on how to check the EGR on K9K engines.

EGR valve status

This function allows the EGR status to be read and the operation of the valve to be checked. The EGR valve status is indicated in a list with a status number.

IFR-50

Test preconditions

Key on or engine running.
Coolant temperature > 80 °C.

Procedure

Start DCU communication, select "Settings" and then "EGR valve status."

Background Check

List the parameters :

Use this list to compare with the indicated value.

STATUS : None

No EGR shutoff, the EGR operates normally according to the DCU programming.

STATUS : 1, 5, 6, 7, 9, 10, 12, 13, 15, 19, 23, 24

Switch off the ignition and wait for 1 minute. Switch the ignition on and check for faults. Check the battery voltage, engine stopped and engine running. If there is no fault code flagged or memorised, restart the vehicle and check the idle speed. Do not rev the engine to not run it too fast.

STATUS : 3, 14, 16

Accelerate to above idle for a few seconds.

STATUS : 2

Check that the clutch pedal is fully up and that the vehicle is stationary.

STATUS : 4, 17

Check for any fault codes present and recorded and correct them.

STATUS : 8

Reset the EGR offsets by using the command “Programming reset" and select "EGR

valve".

STATUS : 11, 22

Allow the engine temperature to rise until the out of service setting disappears.

STATUS : 18

Check that the DPF regeneration running has been fully completed.

STATUS : 20

Allow the engine temperature to fall until the out of service setting disappears.

STATUS : 21

Atmospheric pressure too low, the EGR valve is deactivated

To help isolate the cause of an EGR-related problem with the valve, passages, or control system, follow the recommended procedures below:

If normal results were obtained, the EGR-related problem is being caused by a malfunctioning control system (vacuum-operated valves only). For electro-mechanical valves, a normal result indicates that the EGR-related concern is intermittent, check for stored fault codes with diagnostic equipment.

If there is no change in idle quality, then either the EGR valve is inoperative or the EGR passages are completely restricted. A slight change in idle quality is indicative of partially clogged passages.

Replacing the EGR valve

Remove the carbon residues from around the valve housing before installing a new one.
Scrupulously clean the valve mounting surface and position the new valve and its gasket.
Tighten the fixings according to the fitting recommendations.
Connect the vacuum hose and the electrical wiring.
