The invention discloses an intelligent dynamic charging method for a storage battery of a new energy electric vehicle, and the main design concept of the intelligent dynamic charging method is that the healthy working state of the storage battery of the electric vehicle can be effectively ensured through an intelligent charging strategy combining software and hardware under the condition that the cost of the new energy vehicle is not increased. Establishing a relation between energy consumption and the health degree of the storage battery according to factors such as voltage values of the storage battery and environment temperature at different moments after power-off and by combining the characteristics of the storage battery, predicting the power supply moment during the dormancy period according to the relation, and providing a mechanism for dynamically adjusting the power supply moment according to dynamic voltage monitoring. Besides, when the storage battery is actually charged, the current energy of the storage battery is judged and the duration required for charging is decided by detecting the environment temperature, the voltage value of the storage battery and the charging current in real time.
本发明公开了一种新能源电动汽车蓄电池智能动态补电方法,本发明的主要设计构思在于,在不增加新能源汽车成本的情况下,通过软硬件结合的智能补电策略,能够有效保证电动汽车蓄电池的健康工作状态。具体是根据下电后不同时刻的蓄电池电压值、环境温度等因素,结合蓄电池特性,建立能量消耗与蓄电池健康度的关系,并以此来预测在休眠期间的补电时刻,以及提出了根据电压动态监测进行补电时刻动态调整的机制。此外,在实际为蓄电池补电时,通过实时的环境温度、蓄电池电压值、补电电流检测,对蓄电池当前能量进行判定并决策补电所需持续的时长。
