| 摘要: |
| 为了提高对动力电池健康程度评估的准确性，针对动力电池(组)，给出一种基于动力电池的全寿命周期特征参数的评估算法。以动力电池的安全使用和准确评估为切入点，关注动力电池SOC的算法与动力电池SOH的检测方式，引出动力电池全生命周期在线监测管理系统的设计思想。以动力电池标称数据为基础，基于动力电池日常充电/换电、放电数据对动力电池进行检测，对检测中发现的隐患的动力电池统一调度，并制定电池维护/检修计划。评估结果表明，以电池箱（组）为分析/管理对象，根据动力电池的电气特征量采用对应策略对电池箱进行评估，可较为准确的评估动力电池当前的健康状态。且可预测出动力电池的使用趋势，从而达到“提高动力电池使用的安全性，延长电池的使用生命，减少运营成本”的目的。 |

| Abstract: |
| In order to improve the assessment accuracy of power battery health degree, this paper provides an assessment arithmetic based on power battery life cycle characteristic parameter for power battery box (group). Starting with the safe use and accurate assessment of power battery, concerning the SOC arithmetic and SOH test methods of power battery, it leads to the design concept of on-line monitoring supervision system for power battery life cycle; with the power battery nominal data as basis, it tests the power battery based on its daily charging/switching and discharging data, to conduct unified management of power battery with hidden danger during testing and make battery maintain/servicing plan. The assessment result shows that with battery box (group) as analyzing/managing object, assessing battery box with corresponding strategies according to power battery electrical features, we can assess the current health condition of power battery relatively accurately, and forecast the use tendency of power battery, thus achieving the goal of improving the security of power battery use, prolonging its serving life and reducing the operating costs. |
