Sanyo Electric Co Ltd exhibited a Li-ion rechargeable battery module for hybrid vehicles and a Li-ion rechargeable battery cell for plug-in hybrid vehicles at the 40th Tokyo Motor Show, which is open to public from Oct 27 to Nov 11, 2007.The Sanyo battery module for hybrid vehicles measures 800 mm x 322 mm x120mm weighs 37.5kg and has a capacity of 31L. The Sanyo battery module for hybrid vehicles uses 72 cells connected in series to generate a voltage of 266V.
Sanyo Electric did not reveal the electric power capacity and output of the module. But assuming that the current capacity of the cell is 6-6.5Ah, which is on par with that of the existing Ni-MH rechargeable batteries designed for hybrid vehicles, the power capacity is expected to reach approximately 1.6-1.7kWh.
Sanyo also exhibited a Li-ion rechargeable battery cell for plug-in hybrid vehicles at its exhibition booth. The cell has a current capacity of 20Ah.
