一种多串锂电组全程主动均衡方法研究与设计

Research and design of a kind of lithium battery group active equilibrium method

锂电池组在使用过程中存在充放电速率不一致,它会导致锂电池使用效率降低并对锂电池本身造成伤害,因此锂电池组在使用过程中需要采用均衡措施。通常采用电阻被动均衡,这种方法存在很多缺陷。提出一种主动均衡方法,采用这种方法可以实现低成本全程高效均衡。

The charging and discharging rates of lithium battery in the use process are not consistent, which may lead to the low efficiency and damage of lithium battery. So, the lithium battery packs in the use process need a balanced method. Usually, a balanced resistance is adopted, which has many defects. A method of active equilibrium was proposed, which could realize the low cost efficient balance.
