The invention discloses a charging method and system for a nickel-metal hydride battery of a vehicle, and is applied to the technical field of vehicle engineering.The method comprises the steps that under the condition that the voltage of a storage battery is lower than a uniform charging voltage point corresponding to a preset highest temperature value, a first preset current value is adopted for charging the storage battery in a first constant current stage; under the condition that the voltage of the storage battery reaches the uniform charging voltage point, carrying out second constant current stage charging on the storage battery by adopting a second preset current value; under the condition that the duration of charging in the second constant current stage is lower than the first preset duration and the temperature of the storage battery does not exceed the maximum temperature threshold value, performing third constant current stage charging on the storage battery by adopting a third preset current value; when the charging duration of the third constant current stage reaches a second preset duration, entering a floating charging stage; wherein the first preset current value is greater than the second preset current value, and the first preset duration is greater than the second preset duration, so that the storage battery is charged, and the charging efficiency and the safety are high in the whole charging process.

    本发明公开了一种车辆的镍氢电池充电方法及系统,应用于车辆工程技术领域,该方法包括:在蓄电池的电压低于预设最高温度值对应的均充电压点的情况下,采用第一预设电流值对蓄电池进行第一恒流阶段充电;在蓄电池的电压达到均充电压点的情况下,采用第二预设电流值对蓄电池进行第二恒流阶段充电;在采用第二恒流阶段充电的时长低于第一预设时长、且蓄电池的温度未超过最温度阈值的情况下,采用第三预设电流值对蓄电池进行第三恒流阶段充电;在第三恒流阶段充电时长达到第二预设时长时,进入浮充充电阶段;其中,第一预设电流值大于第二预设电流值,第一预设时长大于第二预设时长,从而实现对蓄电池的充电,整个充电过程中充电效率高、安全性高。
