Abstract

The invention discloses a battery testing station and a testing method thereof. The battery testing station comprises a plurality of groups of battery charge and discharge testing ports, a switching switch group and a controller. Every group of battery charge and discharge testing port comprises a battery voltage testing port, a battery charging unit and a battery discharging unit; the switching switch comprises a plurality of groups of switching switches, every switching switch comprises switches K1, K2 and K3 which are connected to the battery voltage testing port, the battery discharging unit and the battery charging unit of the corresponding group of the battery charging and discharging port respectively; the controller is connected with the switching switch group through a PCI (peripheral component interconnect) bus to collect the voltage data of every battery voltage testing ports and controls the switching actions of every switch of the switching switch group through a serial bus. By means of a plurality of charge testing ports, the battery testing station can perform charge and discharge testing on multiple battery sets simultaneously, thereby improving the production testing efficiency; testing results can be automatically stored in the controller and uploaded to a local area network and accordingly facilitate quality monitoring.

Description

technical field [0001] The invention relates to the field of battery testing, in particular to a battery testing station for battery charging, discharging and battery voltage and a testing method thereof. Background technique [0002] Ni-MH batteries are composed of hydrogen ions and metal nickel, and the power reserve is 30% more than that of Ni-Cd batteries. Due to the strict requirements for the charging and discharging of Ni-MH batteries, in order to improve the service life of Ni-MH batteries, the Ni-MH batteries shipped from the factory It is necessary to conduct charge and discharge tests. The battery test station is an instrument for measuring the internal resistance and voltage of the battery in use. The traditional battery test station cannot meet the needs of battery charge and discharge tests. Contents of the invention [0003] The object of the present invention is to provide a battery testing station and a testing method for battery charging, discharging and...
