我们研究了优化控制一组非理想可充电电池的问题，这些电池可以共享以在某个指定时间段内执行给定量的工作。我们寻求通过优化控制每个电池的放电和充电过程来最大化所有电池在此期间结束时的最小剩余能量。将电池建模为动态系统，我们采用动能电池模型（KBM）并在放电和充电不能同时发生的约束下制定最优控制问题。我们证明，只要这种策略可行，最优解决方案就必须使所有电池的剩余能量相等。这简化了随后导出问题的显式解决方案的任务。
We study the problem of optimally controlling a set of non-ideal rechargeable batteries that can be shared to perform a given amount of work over some specified time period. We seek to maximize the minimum residual energy among all batteries at the end of this period by optimally controlling the discharging and recharging process at each battery. Modeling a battery as a dynamic system, we adopt a Kinetic Battery Model (KBM) and formulate an optimal control problem under the constraint that discharging and recharging cannot occur at the same time. We show that the optimal solution must result in equal residual energies for all batteries as long as such a policy is feasible. This simplifies the task of subsequently deriving explicit solutions for the problem.
