| description | The invention provides a lithium ion battery low-temperature charging lithium precipitation evaluation method and related equipment, and the method comprises the steps: obtaining a reference voltage-SOC curve, an easy lithium precipitation SOC interval and a lithium precipitation threshold value of an evaluated battery at a working condition temperature according to the working condition temperature and a battery system; acquiring a voltage-SOC curve when the battery is charged at the working condition temperature and the target rate current, and determining a polarization potential to be evaluated according to the voltage-SOC curve, the easily-separated lithium SOC interval and the reference voltage-SOC curve; and comparing the polarization potential to be evaluated with a lithium precipitation threshold value, and determining whether the battery has a lithium precipitation risk or not. And the convenience and accuracy of lithium precipitation evaluation are improved.
