A nickel–metal hydride battery (NiMH or Ni–MH) is a type of rechargeable battery. The chemical reaction at the positive electrode is similar to that of the nickel–cadmium cell (NiCd), with both using nickel oxide hydroxide (NiOOH). However, the negative electrodes use a hydrogen-absorbing alloy instead of cadmium.
Primearth EV Energy Co., Ltd. (abbreviated as PEVE) is a Japanese manufacturer of prismatic nickel–metal hydride (NiMH) and lithium-ion battery packs for hybrid electric vehicles, located in Shizuoka Prefecture, Japan. PEVE's products had been solely based on NiMH until early 2011 when the company has started mass production of Li-ion battery.

Panasonic's fourth-generation Eneloop batteries, in AA and AAA sizes Panasonic Eneloop Smart & Quick Charger BQ-CC55 Sanyo Eneloop battery charger. Eneloop (Japanese: エネループ, Hepburn: Enerūpu), stylized as eneloop, is a brand of 1.2-volt low self-discharge nickel–metal hydride (NiMH) rechargeable batteries and accessories developed by Sanyo [1] and introduced in 2005.
Subsequent models featured an Ovonics NiMH battery, rated at 77 Ah with 343 volts (26.4 kWh, 95.0 MJ). [49] Cars with the lead–acid pack had a range of 80 to 100 miles (130 to 160 km), [ 50 ] while the NiMH cars could travel 120 to 140 miles (190 to 230 km) between charges. [ 14 ]
The battery pack also contains a variety of temperature, voltage, and current sensors. Collection of data from the pack sensors and activation of the pack relays are accomplished by the pack's battery monitoring unit (BMU) or BMS. The BMS is also responsible for communications with the vehicle outside the battery pack. [94]
ECD Ovonics, half owner of Cobasys, was founded in 1960 by Stanford R. Ovshinsky, [5] a scientist and inventor, with his wife and collaborator Iris M. Ovshinsky. [6] [7] Mr. Ovshinsky invented a variation on the NiMH battery, and ECD Ovonics holds crucial patents on some types of NiMH battery technology, licensing them to all major NiMH battery producers.
