本文提出了辅助电源模块（APM）和高压电池非耗散平衡硬件的集成。拟议的电池平衡 APM 预计将通过提供两种功能来降低非耗散电池平衡的成本：高压电池单元的平衡和低压电池的充电。本文提出了两种解决同步平衡和充电问题的模型预测控制策略。这两种方法都可以实现不平衡充电，从而增加高压电池的有效容量。单片控制器将平衡和充电问题作为单个优化问题来解决。相反，解耦控制器定义了单独的充电控制法则，以实现更高的带宽，例如，对于没有专用低压电池的系统。电池平衡 APM 概念已在软件在环和实验测试台上得到验证。
This paper proposes the integration of the auxiliary power module (APM) and nondissipative balancing hardware of a high-voltage battery. The proposed battery-balancing APM is projected to reduce the costs of nondissipative battery balancing by providing two functionalities: balancing of the high-voltage battery cells and charging of the low-voltage battery. This paper proposes two model predictive control strategies that address simultaneous balancing and charging. Both approaches make unbalanced charge available that increases the effective capacity of the high-voltage battery. The monolithic controller solves the balancing and charging problem as a single optimization problem. In contrast, the decoupled controller defines a separate control law for charging to achieve a higher bandwidth, e.g., for systems without dedicated low-voltage battery. The battery-balancing APM concept is validated on a software-in-the-loop and experimental test bench.
