Problems solved by technology

[0002] The existing battery current acquisition circuit can only collect the current, and cannot dynamically calibrate the error of the current acquisition circuit in real time. Therefore, the error introduced by the device in the battery current acquisition circuit will be included in the entire current acquisition error within the full working range. Accumulation, cannot be completely eradicated, affecting the accuracy of the final collection of battery current

Abstract

The invention discloses a battery current acquisition device and calibration method, a battery, a battery management system and an electronic device. The battery current acquisition device comprises ashunt, a switch module and a control module, the switch module is arranged between the shunt and the control module; the shunt is used for acquiring a current signal of a battery cell module in the battery; the control module is used for controlling the switch module to disconnect the shunt from the control module, acquiring voltage values at two ends of the control module and taking the voltagevalues as calibration voltage values; and the control module is also used for controlling the switch module to connect the shunt with the control module, acquiring voltage signals at the two ends of the shunt and calibrating the values of the voltage signals at the two ends of the shunt according to the calibrated voltage values. According to the device and method, the battery management system and the electronic device, the current collection error can be reduced, the current collection precision is improved, and the cost is reduced.

Description

technical field [0001] The present application relates to the technical field of vehicles, in particular to a battery current acquisition device, a battery management system including the battery current acquisition device, a battery, a battery current calibration method, and an electronic device. Background technique [0002] The existing battery current acquisition circuit can only collect the current, and cannot dynamically calibrate the error of the current acquisition circuit in real time. Therefore, the error introduced by the device in the battery current acquisition circuit will be included in the entire current acquisition error within the full working range. Accumulation cannot be completely eradicated, affecting the accuracy of the final battery current collection. Contents of the invention [0003] This application aims to solve at least one of the technical problems existing in the prior art. For this reason, the present application proposes a battery current...
