Abstract
A portable high voltage charging apparatus (HVCA) can be configured to controllably charge a hybrid electric vehicle (HEV) traction battery using energy provided by a low voltage (LV) lead acid vehicle battery. An HVCA can include a DCDC converter configured to boost a lower input voltage from the LV battery to a higher output voltage provided to the HV battery. The HVCA can be configured with a traction battery interlock, allowing offline charging of the traction battery. In an example embodiment, an HVCA can be configured to communicate with an HV battery control module via a CAN bus. An HVCA can be configured to transfer energy to the HV battery for a predetermined time period, then automatically stop the transfer process. An HVCA can be configured to receive user input to start and/or stop a charging process. An example embodiment can include a supplemental charger to boost LV battery voltage.
