摘要

高能量密度LiFePO4电池在电动汽车应用中发挥着重要作用。由于充电要求严格，电池平衡是电池管理系统(battery management system, BMS)对该类电池充电的必要功能。通常，电池平衡电路有两种类型，即有源平衡电路和无源平衡电路。由于简单，我们选择了无源电路。从技术上讲，无源平衡在电池平衡时存在能量损失。本研究主要探讨了三种能量损失的无源平衡方案，以及在各种条件下，如考虑平衡所有电池之间的电流或电荷状态(SOCmax - SOCmin)。仿真结果表明，不同的平衡方案对能量损失影响不大。

A Study of energy loss in LiFePO4 battery-balancing schemes for electric vehicle applications

High energy density LiFePO4 battery plays an important role in the EV application. Due to strictly charging requirement, battery balancing is a necessary function in a battery management system (BMS) for charging this type of battery. Normally, there are two types of battery balancing circuit, i.e. active and passive balancing circuit. Because of simplicity, a passive circuit is chosen. Technically, passive balancing has energy loss while batteries are balancing. This research is focused on exploring three kinds of passive-balancing schemes about energy loss and at various conditions e.g. considering at balancing current or state of charge among all cells (SOCmax - SOCmin). The simulation results show that the different balancing schemes do not have significant effect on energy loss.
