The invention discloses an analog battery system comprising a voltage generation circuit. The voltage generation circuit comprises a control module, a digital-to-analog conversion module, a voltage stabilizing module, and a feedback module; the control module outputs a voltage preset signal to the digital-to-analog conversion module; the digital-to-analog conversion module converts the voltage preset signal into an analog voltage; the voltage stabilizing module performs voltage stabilizing on the analog voltage output by the digital-to-analog conversion module, and outputs a stabilized analogvoltage; the feedback module receives the stabilized analog voltage and feeds back the stabilized analog voltage to the control module; the stabilized analog voltage output by the voltage stabilizingmodule is the output voltage of the analog battery system; and the control module adjusts the output voltage of the analog battery system according to the output voltage value of the analog battery system and the voltage preset signal, so that the output voltage value of the analog battery system approaches the voltage preset signal. According to the analog battery system, the precision and the resolution of the output voltage of the analog battery system are improved.
Description
technical field [0001] The present invention relates to the technical field of battery management systems, and more specifically, to a simulated battery system. Background technique [0002] When using a real battery pack, because the voltage of the battery pack itself is uncontrollable, the external discharge or self-discharge parameters of the real battery pack are inconsistent during the external power supply process. Long-term use will cause inconsistent voltages of batteries from all walks of life, resulting in unbalanced power of each battery. Since the real battery pack needs to be charged, the use of each battery pack and its own reasons are different, which makes it easier to charge unevenly and damage the battery. In the test field that needs to use batteries, such as the detection of the balance module, etc., the real battery is obviously not suitable, and the reason of the real battery itself may cause the deviation of the test results. Therefore, in this scenari...
