Abstract

Techniques for pre-charging buses of an electric vehicle include causing a first DC bus, while a high-voltage battery is decoupled from the first DC bus, to be pre-charged by a low-voltage battery using a first DC-DC converter coupled between the first DC bus and the low-voltage battery. The techniques also include causing a second DC bus to be pre-charged using a second DC-DC converter coupled between the first DC bus and the second DC bus, which may be performed after or during pre-charging the first DC bus. The techniques additionally may include causing an AC bus to be pre-charged using a DC-AC converter coupled to the second DC bus and to the AC bus, while a grid contactor is open.
