混合动力汽车能量管理[外文翻译]
摘要
一个混合动力汽车是由储存在电池或飞轮中的能量和燃烧发动机中的油料产生的能量共同驱动。消耗的能量以及排放空气的质量可以通过优化电池的和发动机的效率以及在期望的驱动条件下所传输的能量输出。车辆使用寿命成本可通过将发动机在恒定速度和能量下运行，也可通过避免电池的流失而实现最小化。
包含优化计算机的车载能量管理者可以跟踪电池的实时能量，当在给定的路段它还可优化电池和发动机的负载分配。无论何时只要两者之一是寿命缩短的深度放电电池，它就能命令发动机传出更多的能量。汽车设计者需要设计一个工程技术分析系统来优化发动机和电池的等级。因此他需要知道汽车在特定路段以理想速度翻越山岭时以及在每天不同风速下所需供求的能量。
在辅助性的分析中，我们通过拉格朗日微积分方法建立了混合动力汽车的模型。我们把这个模型应用到了电动汽车之中，该电动汽车在200米路程当中通过了多种山坡。在爬坡中，能量消耗很不理想。在特定的行驶时间，无论是在慢慢地爬坡中还是快速地下滑中，都未能节省能量。在计算中，我们也忽略了推动力的效率。下一步将把发动机的不同效率以及在不同车速下发动机的牵引力加入到模型之中。

Abstract
A hybrid electric vehicle is propelled with stored energy from a battery or flywheel, plus energy produced by burning fuel in an engine. The cost of the energy consumed, as well as the quantity of air pollutants released, can be reduced by optimizing (1) the ratings of the battery and engine, and (2) the power output that will be delivered by each source under the expected driving conditions. Life-cycle cost can be minimized by running the engine at a constant speed and power, and by avoiding deep discharges of the battery.
An on-board "energy manager," which contains an embedded computer, can track the energy content of the battery and optimize the load division between the battery and engine when given a travel time by the driver over a specified route. It can command the engine to deliver more power whenever the alternative is a life-shortening deep discharge of the battery. The vehicle designer needs to perform a system-engineering analysis to optimize the ratings of the engine and battery. For this he needs to understand the power required to move the vehicle at desired speeds over hills on the expected routes, and through headwinds that vary from day to day.
