The invention relates to battery linear charging and discharging test equipment, a control method thereof and a computer readable storage medium. The device comprises a direct-current power supply, aDC conversion circuit, an MOS transistor Q2, an MOS transistor Q3, a multiplexer switch K1, an output positive end Uout+, an output negative end Uout-, a controller and at least two DAC channels. TheDC conversion circuit takes electricity from the direct-current power supply. The positive electrode output end of the MOS transistor Q1 is connected in series with the MOS transistor Q2 and one inputend of the multiplexer switch K1. The common end of the two-way selector K1 is connected to the output positive end Uout+. The negative electrode output end of the DC conversion circuit is connectedto the output negative end Uout-, the other input end of the multiplexer switch K1 is connected to the output negative end Uout-through the MOS transistor Q3, and the controller is connected with theMOS transistor Q2 and the G electrode of the MOS transistor Q3 through two DAC channels. The linear variable characteristic of the resistance value of the MOS tube is utilized, constant-current and constant-voltage charging and speed-variable discharging of the battery are achieved, the circuit structure of the device is exquisite and simple, and the purpose of low cost can be achieved.
Description
technical field [0001] The invention relates to the field of battery testing, in particular to a battery linear charging and discharging testing device, a control method thereof, and a computer-readable storage medium. Background technique [0002] The battery needs to be charged and discharged before leaving the factory. The charging process needs to be charged at a constant current first, and then charged at a constant voltage. The discharging process is relatively simple and can be discharged directly. [0003] In order to meet the above requirements, the existing battery charge and discharge test equipment needs to have a constant current output circuit, a constant voltage output circuit and a discharge load at the same time. The structure is complex and the cost is high. Contents of the invention [0004] In order to improve the deficiencies of the prior art, the invention provides a battery linear charging and discharging testing device with simple structure and low ...
