1. A vehicle energy-storage system comprising:
a plurality of modules, each module including:
two half modules coupled together, each half module including:
a plurality of cells, the cells being cylindrical rechargeable lithium-ion cells each having a first end and a second end, the first end distal from the second end, and having an anode terminal and a cathode terminal being disposed at the first end; andan enclosure having the cells disposed therein, the enclosure including a power connector electrically coupled to the plurality of cells;a main power connector electrically coupled to the power connectors of the two half modules; anda heat exchanger disposed between the two half modules, the heat exchanger being thermally coupled to each of the plurality of cells of the two half modules at the second end, the heat exchanger being fluidly coupled to a coolant system, the heat exchanger transferring heat from the plurality of cells; a tray having the plurality of modules disposed therein, the tray including:
a positive bus bar;a negative bus bar, the positive and negative bus bars being separately electrically coupled to the main power connector associated with each of the plurality of modules; and the coolant system for circulating coolant being pumped into the tray such that each of the modules is at approximately the same predetermined temperature. |
