The invention provides an electric motorcycle battery protection system and a protection method thereof, and relates to the technical field of battery protection. Determining the state balance characteristic of the single battery in the active balance mode according to the characteristic difference between the charging states and the charging balance characteristic; obtaining the health state information of a single battery in the electric motorcycle, and determining the balance supplement amount of each battery pack in a passive balance mode according to the aging loss characteristic and the energy loss characteristic of each battery pack in the electric motorcycle; the charge state balance degree of the electric motorcycle under dual-mode balance is determined according to the balance supplement amount and the state balance characteristics, and balance adjustment is carried out on the charging protection strategy of the electric motorcycle based on the charge state balance degree. Therefore, the charging safety balance of the electric motorcycle can be improved.

    本申请提供一种电动摩托车电池保护系统及其保护方法,涉及电池保护技术领域,从各个充电信息中提取电动摩托车中各个电池组的充电状态,进而通过各个充电状态之间的特征差异和充电平衡特性确定主动平衡模式下单体电池的状态平衡特征;获取电动摩托车中单体电池的健康状态信息,根据电动摩托车中各个电池组的老化损耗特征和能量损耗特性确定各个电池组在被动平衡模式下的平衡补充量;通过平衡补充量和状态平衡特征确定电动摩托车在双模式平衡下的荷电状态均衡度,基于荷电状态均衡度对电动摩托车的充电保护策略进行均衡调节,本申请可实现电动摩托车各个电池组充电过程中荷电状态的均衡调节,从而可提高电动摩托车充电的安全平衡性。
