High Performance Nickel-Metal Hydride Battery Technologies for HEV

摘要

1. Achieved high power output by decreasing battery internal resistance Maximum current of 200A(HR-DP) and 470A(HR-MP) 2. Achieved longer cycle life by clarifying the deterioration mechanism during cycle 93% maximum current vs. initial stage after 14,000 cycles at 50A pulse cycle. 3. Achieved excellent high-temperature charge characteristics by controlling oxygen generation 80% efficiency for 80% charging amount at 60℃ ambient temperature.
