Description
Technical Field
[0001] This utility model relates to a nickel-metal hydride battery, specifically a high-capacity power nickel-metal hydride battery, belonging to the field of new energy battery technology. Background Technology
[0002] Currently, most new energy vehicle batteries use lithium-ion batteries and nickel-metal hydride batteries. Compared with lithium batteries, nickel-metal hydride batteries have more mature technology, better high and low temperature performance, better safety performance, and can be charged and discharged at high currents. However, their higher cost mainly restricts their application and popularization in automobiles. Nevertheless, nickel-metal hydride batteries still have advantages and a market in hybrid electric vehicles and cold-weather electric vehicles. This is because hybrid electric vehicles have smaller battery capacity and relatively lower cost, and cold-weather electric vehicles currently only have nickel-metal hydride batteries that can be charged and discharged at low temperatures, especially wide-temperature nickel-metal hydride batteries, which can operate from -45℃ to 70℃.
[0003] However, the assembly of existing wide-temperature-range nickel-metal hydride battery modules and their installation and fixation within the battery pack are difficult, while large-capacity nickel-metal hydride battery modules suffer from high costs and complex assembly and disassembly.
[0004] Therefore, a high-capacity nickel-metal hydride battery is proposed here. Utility Model Content
