New Lithium Battery and Management System Doubles Range of ZAP Electric Cars

SANTA ROSA, Calif., May 18, 2010 (BUSINESS WIRE) -- Electric vehicle pioneer ZAP(ZAAP 0.38, -0.01, -2.56%) has begun shipping lithium battery systems for various models of its electric cars, trucks, vans and scooters, offering at least four times the life of standard lead-acid batteries and twice the driving range. The new battery system is the first turnkey, drop-in replacement battery system that fits in the same space as the G-31 lead acid batteries used in many of ZAP's vehicles, equipped with a BMS (battery management system) that increases reliability and extends range.

The lightweight lithium battery system is used in the ZAP Alias, allowing it to drive up to 100 miles on a single charge. In China, ZAP's new fleet vehicles use a similar system for its electric taxis and corporate vehicles based on the Jonway A380 SUV. A sub-chassis array of more than 100 battery cells is networked with an electronic monitoring system, ensuring that temperature and voltage of each cell are in balance and that electricity is automatically rerouted should any of the cell voltages change.
