Reducing Li-ion battery charge times through rapid-charging is proving to be essential to enable the widespread adoption of electric vehicles. However, rapid-charging accelerates the degradation of batteries by reducing both the power and capacity of individual cells, leading to shorter and more unpredictable battery lifetimes as well as higher warranty and servicing costs for vehicle OEM's.If battery management systems could more accurately track changes in the health of the cells within a battery over its lifetime, they could adapt the behaviour of the battery accordingly to slow down the rate of degradation. The goal of the ARC Project -- a feasibility study being led by Edge Mobility -- is to evaluate the potential to extend the lifetime of rapid-charged battery systems with new battery management technologies that can accurately estimate changes in the health of the cells and control the battery's performance accordingly.

事实证明，通过快速充电减少锂离子电池的充电时间对于推动电动汽车的广泛采用至关重要。然而，快速充电会同时减少单个电池的功率和容量，从而加速电池的退化，导致电池寿命更短、更不可预测，以及车辆OEM的保修和维修成本更高。如果电池管理系统能够更准确地跟踪电池在其生命周期内电池健康状况的变化，它们可以相应地调整电池的行为，以减缓退化的速度。ARC项目--由Edge Mobility牵头的一项可行性研究--的目标是评估使用新的电池管理技术延长快速充电电池系统寿命的潜力，这些技术可以准确地估计电池健康状况的变化，并相应地控制电池的性能。
