The invention discloses a storage battery charging method, a control device and an electric automobile. The storage battery charging method comprises the steps ofmonitoring the current state of healthSOH and the current remaining electric quantity SOC of a storage battery when the electric automobile is in a static working condition,if the characterization parameter value of the current SOH is larger than or equal to a first preset parameter value and smaller than a second preset parameter value, when the current SOC is smaller than or equal to a first preset remainingelectric quantity value,charging the storage battery, if the characterization parameter value of the current SOH is greater than or equal to the second preset parameter value and when the current SOC is less than or equal to a second preset remainingelectric quantity value, charging the storage battery,wherein the second preset remaining electric quantity value is different from the first preset remaining electric quantity value. According to the embodiment of the invention, the problems that the charging end set threshold value cannot be reached for a long time and the whole automobile consumes power for a long time when the state ofhealth of the storage battery is poor are solved.
本发明公开了一种蓄电池充电方法、控制装置及电动汽车,所述蓄电池充电方法,包括:在所述电动汽车处于静态工况时,监测蓄电池的当前健康状况SOH和当前剩余电量SOC;若所述当前SOH的表征参数值大于或等于第一预设参数值,小于第二预设参数值,则当所述当前SOC小于或等于第一预设剩余电量值时,对所述蓄电池进行充电;若所述当前SOH的表征参数值大于或等于所述第二预设参数值,则当所述当前SOC小于或等于第二预设剩余电量值时,对所述蓄电池进行充电;其中,所述第二预设剩余电量值与所述第一预设剩余电量值不同。本发明的实施例,解决了在蓄电池健康状态差时,长时间达不到充电结束设定阈值且整车长时间耗电的问题。
