Problems solved by technology

However, in this way, battery information may be collected while equalization is being performed. Since the equalization process may cause fluctuations in battery information, this may lead to inaccurate battery information collected, which in turn makes it necessary to balance when there are single batteries. , the calculated equalization duration is inaccurate, and the equalization effect is poor

Embodiment Construction

[0030] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0031] see figure 1 , is a schematic diagram of a battery balancing system according to an embodiment of the present disclosure. The battery balancing system includes: a control module 101 , an acquisition module 102 and a balancing module 103 . The battery balancing system can be used to balance the battery pack 104 .

[0032] In one embodiment, each single battery corresponds to a collection module 102 and a balancing module 103 . The acquisition module 102 and the balance module 103 corresponding to the same single battery are respectively connected to the control module 101 through different control channels. The control module may include a control c...

Abstract

The present disclosure relates to a battery equalization method, system, vehicle, storage medium, and electronic equipment. The method includes: acquiring the SOC value of a single battery to be balanced in a battery pack; acquiring a reference SOC value required for equalization; according to the The SOC value of the single battery to be balanced, the reference SOC value and the preset equalization duty cycle determine the target equalization duration of the single battery to be balanced, wherein the equalization duty cycle is the equalization within a unit cycle The ratio of the time period to the unit period, the unit period includes the equalization period and the sampling period; according to the target equalization time length, the balance of the single battery to be balanced is controlled during the equalization period of the unit period.

Description

technical field [0001] The present disclosure relates to the technical field of control, and in particular, relates to a battery balancing method, system, vehicle, storage medium, and electronic equipment. Background technique [0002] Large-capacity batteries that provide power energy for electric vehicles are often called power batteries. Vehicle power batteries generally consist of multiple single cells connected in series to form a module. With the use of the battery, the difference between the individual batteries gradually increases, and the consistency between the individual batteries is poor. Due to the short plate effect of the battery, the capacity of the battery pack is limited, so that the capacity of the battery pack cannot be fully utilized, resulting in the failure of the battery pack. Overall capacity is reduced. On the other hand, after the differences among individual batteries gradually expand, some single batteries will be overcharged and some single ba...
