A battery management system (BMS) connected to a battery having a positive end and a negative end, the BMS also connected to a fast charger. The BMS includes: a battery management controller protection circuit board (PCB) configured to manage an operation of the battery; a charger controller PCB configure to control fast charging of the battery; and a fast charge contactor positioned between one of the positive and negative ends of the battery and the fast charger. No fast charge contactor is positioned between the other of the positive and negative ends of the battery and the fast charger. The BMS is configured to determine a location of an isolation fault by connecting and disconnecting one or more resistors.

Low cost fast charge contactor for high voltage battery management systems

A combined battery management system, charger, and direct current converter (BCD) for an electric vehicle is disclosed. The combined unit includes an enclosure enclosing: an on board charger (OBC); a direct current converter (DC-DC); and a single cold plate thermally coupled to both the OBC and the DC-DC, the single cold plate configured to provide cooling for both the OBC and the DC-DC. The combined unit also includes a plurality of 12V terminal posts on the enclosure, at least one of the plurality of 12V terminal posts for 12V in and at least two of the plurality of 12V terminal posts for 12V outs.

Combined BMS, charger, and DC-DC in electric vehicles

A controller of an electric vehicle is disclosed. The controller includes: a BMS LV module configured to manage a low voltage battery; a BMS HV module configured to manage a high voltage battery; a DC-DC module configured to control a plurality of DC-DC FETs; and an ampSwitch module configured to detect a short on a bus and switch to an open state, and further configured to command the DC-DC module or an alternator to match the low battery's voltage and switch to a closed state when voltage returns to normal.
