The invention provides an electric quantity detection method and device for an electric bicycle. The electric quantity detection method for the electric bicycle comprises the following steps: acquiring battery output power corresponding to multiple target moments from an initial moment to a current moment; based on the battery output power corresponding to a plurality of target moments from the initial moment to the current moment, determining accumulated consumed electric quantity; and sending the accumulative consumed electric quantity to a server, so that the server determines the remaining electric quantity of the electric bicycle based on the accumulative consumed electric quantity and the battery electric quantity at the initial moment. According to the electric quantity detection method and device for the electric bicycle, the battery output power at the multiple target moments is obtained, the accumulative consumed electric quantity of the battery is determined according to the battery output power at the multiple target moments, the residual electric quantity of the electric bicycle is obtained through the server, and the electric quantity of the electric bicycle can be detected according to the batteries with different initial electric quantities. The electric quantity is detected in a targeted manner, the detection error of the residual electric quantity is reduced, and the accuracy is improved.

    本发明提供一种电动自行车的电量检测方法及装置,该电动自行车的电量检测方法包括:获取从初始时刻到当前时刻的多个目标时刻对应的电池输出功率;基于从初始时刻到当前时刻的多个目标时刻对应的电池输出功率,确定累计消耗电量;将累计消耗电量发送给服务器,以供服务器基于累计消耗电量以及初始时刻的电池电量,确定电动自行车的剩余电量。本发明提供的电动自行车的电量检测方法及装置,通过获取到多个目标时刻的电池输出功率,根据多个目标时刻的电池输出功率确定电池的累计消耗电量,并利用服务器来得到电动自行车的剩余电量,能够针对不同初始电量的电池,有针对性地检测电量,降低剩余电量的检测误差,提高准确率。
