A charging system for a high voltage battery includes a pair of contactors each electrically connected to one of positive and negative terminals of the battery and configured to enable charging of the battery when closed; and a controller programmed to generate a notification indicating that one of the contactors is welded closed based on port voltage values achieved while issuing a predetermined sequence of open and close commands to the contactors after charge completion.

High voltage battery contactor arrangement for DC fast charging

An example method of connecting an electric vehicle battery includes welding a landing of a terminal to a bus bar, and pressing a landing of the terminal and the bus bar against one another during the welding. The landing is along a first plane and a base of the terminal is along a second plane that is spaced from the first plane.

Electric vehicle battery attachment assembly and method

An automotive vehicle high voltage bus is connected to a power source by a circuit having a main contactor and a precharge contactor. To energize the bus, the precharge contactor is closed and then the main contactor is closed. Upon completion of precharging, the main contactor is opened and energization of the bus is complete.

A cooling system may be operable to cool a battery pack or other device through a heat exchange operation supported, at least in part, with cycling of a coolant relative to a coldplate or other thermally conducting surface of the device and/or attached thereto. The system may include a coldplate operable to exchange heat with a battery pack; and a coolant tank operable to exchange heat with the coldplate, the tank having a channel for directing a coolant flow in a direction from an inlet of the tank to at least one outlet of the tank and an inlet accumulator between the inlet and a beginning of the channel, wherein the inlet accumulator is wider along the coolant flow direction than the channel and the inlet and having a sloped side leading towards the channel configured to pool the coolant flow prior to entry into the channel.
