Series-mode nickel-metal hydride battery charging and discharging motor

Abstract

The invention relates to a series-mode nickel-metal hydride battery charging and discharging motor, which comprises a charging and discharging unit used for charging and discharging a nickel-metal hydride battery, a motion unit used for clamping the nickel-metal hydride battery and a general controller used for controlling operations of the charging and discharging unit and the motion unit, wherein the charging and discharging unit comprises a power supply cabinet, a charging and discharging power supply, a power supply, a power supply control board, an alarm and a heat dissipation device; themotion unit comprises a motion mechanism cabinet and a clamping mechanism used for clamping the nickel-metal hydride battery, the clamping mechanism comprises an upper probe board assembly, a lower probe board assembly, a driving cylinder, a guide rod, a clamping frame, a tray and a controller. The series-mode nickel-metal hydride battery charging and discharging motor has the beneficial effectsthat a constant-current charging and discharging process can be performed on cylindrical nickel-metal hydride batteries on the tray under a rated current condition, real-time monitoring can be performed on parameters such current, voltage and tray temperature of the batteries in the charging and discharging process, and a corresponding curve is depicted. The series-mode nickel-metal hydride battery charging and discharging motor adapts to dimensions of the cylindrical nickel-metal hydride batteries which change in height and size within a certain range, and is simple and convenient in producttype changing operation.

Description

technical field [0001] The invention relates to a charging and discharging machine for nickel-metal hydride batteries in series. Background technique [0002] Cylindrical Ni-MH batteries are widely used in electric vehicles, electric buses, electric tools, energy storage stations, etc., and have a wide range of application fields. In the series of rechargeable and dischargeable batteries, Ni-MH batteries have the advantages of unique resistance to overcharge and overdischarge, strong high-speed discharge capability, and high safety, and have a wide range of applications. In the production process of cylindrical Ni-MH batteries, pre-charging, formation, and capacity separation are all very important process links. The charge-discharge machine is the main production equipment in this process link, which plays an important role in the quality of the battery. .
