1. Good power performance. A large number of metal materials are used in the nickel hydrogen battery, which has good conductivity and can adapt to high-power discharge. At present, the specific power is more than 1500W / kg.
2. Good low temperature performance. The inorganic electrolyte system is adopted, and the low-temperature performance is better than that of lithium series batteries.
3. Its application is relatively mature. Currently, commercial hybrid electric vehicles such as Toyota Prius and Honda insight hybrid electric vehicles use nickel hydrogen batteries.
4. The management system is relatively simple and the battery has strong over charge and over discharge resistance, so it is unnecessary to monitor the voltage of each single battery.
