According to the accuracy requirement of testing data for the battery management system, a multi-channel and high precision A/D data acquisition circuit was designed based on ADS7953 digital converter. Using dual operational amplifier LM358, the relevant data of the battery voltage, charge-and-discharge bidirectional current and working temperature were obtained and sent to A/D converter, from which the output digital signal was then transmitted to MCU for the subsequent data evaluation. The ex?perimental results show the circuit meets the accuracy requirement of data testing of the battery manage?ment system, and provides a guarantee for the reliability assessment of the battery management system.
