移动设备的使用受到电池寿命的限制。有些设备可以选择连接额外的电池，或使用具有多个电池的智能电池组以延长使用寿命。在这些情况下，在负载上调度电池以利用恢复特性通常可以延长系统寿命。与电池的顺序放电相比，简单的调度方案（例如循环或选择可用的最佳电池）已经提供了很大的改进。在本文中，我们将这些调度方案与使用定价定时自动机电池模型（在 Uppaal Cora 中实现和评估）生成的最优调度方案进行比较。我们看到，在某些情况下，简单调度方案的结果接近最优。然而，最佳时间表也清楚地表明，电池寿命仍有提高的空间。
The use of mobile devices is limited by the battery lifetime. Some devices have the option to connect an extra battery, or to use smart battery-packs with multiple cells to extend the lifetime. In these cases, scheduling the batteries over the load to exploit recovery properties usually extends the system lifetime. Straightforward scheduling schemes, like round robin or choosing the best battery available, already provide a big improvement compared to a sequential discharge of the batteries. In this paper we compare these scheduling schemes with the optimal scheduling scheme produced with a priced-timed automaton battery model (implemented and evaluated in Uppaal Cora). We see that in some cases the results of the simple scheduling schemes are close to optimal. However, the optimal schedules also clearly show that there is still room for improving the battery lifetimes.
