A battery charging assembly includes a load management system, a charging cord with a battery connector, and circuitry for detecting thermal buildup. The load management system monitors the heat buildup in a coiled portion of the charging cord and issues a corresponding signal to control the current flowing through the cord.

A system comprises an EVSE and an electric vehicle having a precharge mode. To charge a battery, the vehicle is connected to the EVSE. In some cases, the battery is unable to energize power buses. For example, if the battery is too cold and has insufficient charge, then the battery will not energize the power buses. If the battery cannot energize the power buses, then a precharge mode is enabled. During the precharge mode, charge is pumped onto two power buses until a setpoint voltage is reached. For example, a precharge circuit pumps charge onto one power bus and a power converter pumps charge from that bus onto a second bus. Once the setpoint voltage is reached, a current source charger is enabled, and energy stored on both buses is used to facilitate the turn-on of the charger, the precharge mode is disabled, and the EVSE charges the battery.

A computer-implemented method for aggregating electric vehicle loads for demand response events includes receiving a demand response (DR) event request from a utility system indicative of a DR event for an area. The DR event request includes at least one event parameter for participation in the DR event. The method includes determining a first original equipment manufacturer (OEM) DR event load for the area based on the DR event request and charging data received from electric vehicles associated with a first OEM. Upon determining the first original OEM DR event load does not meet the at least one event parameter, the method includes aggregating charging data from electric vehicles associated with a second OEM with the first OEM DR event load to determine an aggregated DR load for the area.

A battery cell is made more thermally efficient with the addition of an integrated vapor chamber that extends out from the cell and into an external heat exchange interface. The integrated vapor chamber can contain a working fluid which undergoes phase changes between liquid and vapor phases when there is a temperature differential between the interior and exterior of the cell. The integrated vapor chamber can include a wicking material to transfer the working fluid to the exterior wall of the vapor chamber. The integrated vapor chamber allows for both heating and cooling of the battery cell.
