The invention relates to a battery electric quantity control method, equipment, a control device and a motorcycle. The battery electric quantity control method comprises the following steps of acquiring a voltage of a battery module; under the condition that the voltage is larger than a first set value and the current electric assistance condition is met, a motor being controlled to be switched to a motor state, and the battery module being controlled to supply power to the motor; and acquiring the accumulated time length of the battery module in the power supply state in the current control period, and controlling the motor to be switched to a generator state when the accumulated time length is greater than or equal to the set time so that the motor charges the battery module. By setting the power supply condition and the charging condition, the battery module can be applied to the electric power-assisted vehicle without power shortage. Meanwhile, only a voltage of the battery module needs to be monitored, so cost of the product is reduced compared with that of electric quantity monitoring.

    本申请涉及一种电池电量控制方法、设备、控制装置和摩托车。其中,电池电量控制方法包括步骤:获取电池模组的电压;在电压大于第一设定值且当前满足电助力条件的情况下,控制电机切换至电动机状态,且控制电池模组对电机供电;获取当前控制周期内电池模组处于供电状态的累计时长,并在累计时长大于或等于设定时间的情况下,控制电机切换至发电机状态,以使电机对电池模组进行充电。通过设定供电条件以及充电条件,使得电池模组运用在电助力车辆中能够不亏电。同时,由于本申请仅需要对电池模组的电压进行监控,相较于电量监控降低了产品的成本。
