A cable assembly includes a cable having a first end and a second end. The cable has an electric conductor and a cooling conduit, each of which extends from the first end to the second end. The cooling conduit is adapted to convey a fluid that cools the electric conductor. The cable assembly includes a leak detection module to detect a leak of the fluid from the cooling conduit. The leak detection module includes a power source to generate an input voltage signal which is applied at a first node contact with the fluid. The leak detection module includes a controller to monitor an output voltage signal at the first node and to detect a leak of the fluid from the cooling conduit based on the output voltage signal.

One embodiment can provide a system for conditioning rechargeable battery cells. The system can include a cell-group conditioning module. The cell-group conditioning module can include a cell interface block that includes a cell contact module and a circuit module. The circuit module can be configured to supply power to cells and can be positioned adjacent to the cell contact module. The cell-group conditioning module can further include a cell platform configured to accommodate a number of cells and an actuation mechanism coupled to the cell interface block or the cell platform and configured to reduce a distance between the cell interface block and cell platform, thereby allowing the cell contact module to establish electrical contact with the cells.

System and method for facilitating conditioning and testing of rechargeable battery cells

An inter-protocol charging adapter for equipment to be charged via a bus includes: first connectors corresponding to a first charging protocol that requires the bus to be energized before the equipment closes onto the bus; second connectors corresponding to a second charging protocol that does not energize the bus before the equipment closes onto the bus; and a boost converter coupled to the bus and to at least one of the second connectors, wherein the boost converter uses energy from the second connector to energize the bus before the equipment closes onto the bus.

Inter-protocol charging adapter

A battery charging station is provided that includes a plurality of charge ports, a plurality of power stages where each power stage includes an AC to DC converter and where each power stage provides a portion of the charging station's maximum available charging power, a switching system that is used to couple the output of the power stages to the charging ports, a system monitor that determines current charging station and vehicle conditions, and a controller that controls operation of the switching system in accordance with a predefined set of power distribution rules and on the basis of the current charging station and vehicle conditions. Current charging station and vehicle conditions may include vehicle arrival time, usage fees, vehicle and/or customer priority information, battery pack SOC, and/or intended departure time.

Multiport vehicle DC charging system with variable power distribution according to power distribution rules

A method of distributing charging power among a plurality of charge ports of a battery charging station is provided, where the battery charging station includes a plurality of power stages where each power stage includes an AC to DC converter and provides a portion of the charging station's maximum available charging power, the method comprising the steps of (i) monitoring battery charging station conditions and operating conditions for each charging port; (ii) determining current battery charging station conditions, including current operating conditions for each charging port; (iii) determining power distribution for the battery charging station and the charging ports in response to the current battery charging conditions and in accordance with a predefined set of power distribution rules; and (iv) coupling the power stages to the charging ports in accordance with the power distribution.
