BAIC to introduce EV with battery swap in China in 2011; anticipating China standard for battery swap
TechOn. Beijing Automotive Industry Holding Co Ltd (BAIC) exhibited an EV with a swappable battery at the 25th World Battery, Hybrid and Fuel Cell Electric Vehicle Symposium and Exhibition (EVS25). The battery of the EV can be replaced in five minutes, according to BAIC.
Currently, the Chinese government is planning to standardize a method of replacing EV batteries and set up stations for replacing batteries. And BAIC developed the C71 EV, considering that battery-replaceable EVs are very promising in China.
This time, BAIC showcased the battery pack equipped in the EV. It was developed by Beijing Pride Power Systems Technology Co Ltd. Its capacity and mass are 22kWh and 340kg, respectively. The positive-electrode material of the battery cell is lithium iron phosphate (LiFePO4). The voltage of the cell is 3.2V, and its current capacity is 60Ah.
The C71 EV, due to be launched in 2011, features a water-cooled permanent-magnet three-phase synchronous motor with output of 60 kW and torque of 160 N·m; maximum speed is 160 km/h (99 mph).
