VEHICLE ENERGY-STORAGE SYSTEMS HAVING PARALLEL COOLING

摘要

Provided are systems for vehicle energy storage having parallel cooling comprising a plurality of modules. Each module may comprise two half modules coupled together. Each half module can include a plurality of battery cells. A current carrier of each half module may be electrically coupled to the cells. The cells may be disposed between the current carrier and a plate. Each half module can have the cells, current carrier, and blast plate disposed in an enclosure. The enclosure can have a coolant sub-system for circulating coolant in parallel to the plurality of cells such that each of the battery cells is at approximately the same predetermined temperature. The modules may be disposed in a tray. A coolant system may be provided for circulating coolant across the plurality of modules in parallel such that each of the modules can be maintained at approximately the same predetermined temperature.

1. An energy-storage system having parallel cooling comprising:
a plurality of modules, each module comprising two half modules coupled together, each half module including:
a plurality of battery cells, the battery cells being cylindrical rechargeable battery 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;a current carrier electrically coupled to the battery cells, the cathode terminal of each of the battery cells being coupled to a respective first contact of the current carrier, the anode terminal of each of the battery cells being coupled to a respective second contact of the current carrier;a plate disposed substantially parallel to the current carrier such that the battery cells are disposed between the current carrier and the plate; andan enclosure having the battery cells, current carrier, and plate disposed therein, the enclosure comprising:
a coolant input port;a coolant output port; anda power connector electrically coupled to the current carrier, the enclosure having a coolant sub-system for circulating coolant flowing into the enclosure through the coolant input port and out of the enclosure through the coolant output port in parallel to the plurality of battery cells such that each of the battery cells is at approximately the same predetermined temperature; a tray having the plurality of modules disposed therein; and a coolant system for circulating coolant flowing into the tray across the plurality of modules in parallel such that each of the modules is at approximately the predetermined temperature.
