Quantum Drive Systems- All-Electric LLV

Under contract with the US Postal Service (USPS), Quantum has integrated an all-electric powertrain to the USPS Long Life Vehicle (LLV) to produce an advanced electric postal delivery vehicle. This EV is currently being tested by the USPS and a successful demonstration in the nation's capital could pave the way to broad adoption of battery electric vehicles in the USPS fleet. Electrification of the 178,000-strong LLV segment of the postal delivery fleet, the largest civilian fleet in the country, will help to reduce emissions across the country and reduce dependence on foreign petroleum while supporting the continued development of the US EV industry. Besides the environmental benefits and fuel savings, electric postal vehicles could also serve as valuable energy storage devices for the grid, under Smart Grid technologies.

The short range mail routes with numerous stops make postal delivery vehicles an ideal application for a battery electric vehicle with regenerative braking features. Under this program, Quantum will integrate its proprietary EV-Drive system into a Grumman LLV. The system has been optimized for USPS specific requirements, by incorporating a number of advanced features to maximize the efficiency of the electric drive system while operating in the typical 500-700 stops per day use of a postal delivery vehicle. The 20-25 mile usage range of the USPS vehicle is the result of the energy storage capability of the advanced lithium battery used in Quantum's electric drive system.
