Multi-channel charging and discharging parameter calibration system

The embodiment of the utility model discloses a multichannel charging and discharging parameter calibration system. The calibration device comprises a control panel and a to-be-calibrated power panelwhich are in communication connection, the to-be-calibrated power panel is provided with at least one channel. Each channel is provided with a preset number of datum points; each channel is used for connecting a battery; all the channels are connected with a measuring device in parallel; the to-be-calibrated power panel is used for reporting the electrical parameters to the control panel; the control panel is used for acquiring current electrical parameters; respectively determining respective current reference points according to the sizes of the current electrical parameters; controlling themeasuring device to be switched to obtain the current actual measured value and the next actual measured value; and the calibration module is also used for calculating a function relationship of charging or discharging betwee
