| 抄録 | Nickel-metal hydride (Ni-MH) batteries are widely installed for traction energy storage in HEVs. A battery deteriorates due to chemical reactions. This study is an investigation of battery deterioration parameters and AC impedance characteristics. Battery SOC (State of charge) and battery temperature are major deterioration parameters. Experimental tests were done on the two deterioration parameters which set values widely considered to represented real world usages. The AC impedance of the battery was measured in stable conditions after each test. Battery AC impedance spectroscopy shows the shape of a Nyquist diagram on a complex plane and is able to verify the battery deterioration in both the parameters of the battery SOC and the battery temperature, in the two types of Ni-MH batteries, which are a super lattice structure and a nominal AB5 one. |
