Mitsubishi Motors Corporation (MMC) is developing an ultra-efficient hybrid electric truck as part of the Advanced Clean Energy cars (ACE) Project, an initiative promoted by the New Energy and Industrial Technology Development Organization (NEDO) under the aegis of Japan's Ministry of Economy, Trade and Industry. To achieve the significantly higher energy efficiency and lower carbon-dioxide (CO2) emissions than those of conventional diesel-engine powered trucks (these are used for most distribution of goods in Japan), MMC combined a compressed-natural-gas (CNG) engine with a newly developed series/parallel hybrid drive system. It was presented at the previous International Electric Vehicle Symposiums. For the heavy duty truck with braking energy regeneration system, the key to high performance is high input density (or low internal resistance) that allows the acceptance of instantaneous and large amounts of braking energy. The chargeability (input density) of the new HEV lithium-ion cell has been improved to a level similar to that of a capacitor. A whole battery system is consisted eighty 3.6 V cells connected in series, a battery management unit, a safety switch and a junction box. Battery weight itself is in the 150 kg range. Even including the battery mount and battery management systems, the total weight is still much lighter than conventional lead-acid batteries. This paper gives an overview of the lithium-ion battery system and some test results of the lithium-ion cells developed by MMC for its ACE Project test vehicle.
