A key part of reducing CO2 emissions from vehicles will be the increased electrification of transport through battery electric vehicles and hybrid vehicles. Lithium-ion based chemistries surpass all other rechargeable cells in terms of energy per unit weight and per unit volume and this makes them particularly attractive in vehicle applications. However, the battery is one of the most expensive parts in an electric power-train and therefore it is imperative to ensure that it lasts as long as possible. Battery durability is a significant challenge to commercialisation, and a key way to improve battery durability is to ensure proper management of the cells during use. To this end, battery condition monitoring is vital for the uptake of low carbon vehicles. However, currently available on-vehicle battery monitoring systems use diagnostic methods that are limited to an uncertain estimation of battery state of charge and state of health and provide little information about internal electrochemical processes. The proposed research will develop a much improved condition monitoring system which is not only able to measure state of charge accurately but can also measure cell degradation processes, and predict and prevent cell failure in advance, whilst using the existing drive-train components present in an electric or hybrid vehicle, adding as little additional hardware as possible.

减少车辆二氧化碳排放的一个关键部分是通过纯电动汽车和混合动力汽车提高交通运输的电气化程度。就每单位重量和每单位体积的能量而言，基于锂离子的化学物质超过了所有其他可充电电池，这使得它们在车辆应用中特别有吸引力。然而，电池是电动动力系统中最昂贵的部件之一，因此必须确保其使用寿命尽可能长。电池耐用性是商业化面临的重大挑战，提高电池耐用性的关键方法是确保在使用过程中对电池进行适当的管理。为此，电池状态监测对于低碳汽车的普及至关重要。然而，目前可用的车载电池监测系统使用的诊断方法仅限于对电池充电状态和健康状态的不确定估计，并且提供很少的有关内部电化学过程的信息。拟议的研究将开发一种大大改进的状态监测系统，该系统不仅能够准确测量充电状态，还可以测量电池退化过程，并提前预测和防止电池故障，同时使用电动或混合动力汽车中现有的传动系统组件，添加尽可能少的额外硬件。
