The invention relates to the technical field of battery charging, in particular to an electric bicycle charging method and system considering charging safety, and the method comprises the steps: charging an electric bicycle through employing a multi-segment charging method; the charging limitation of each charging stage is considered, and a staged multi-constraint battery charging strategy is established; a multi-section constant-current charging particle swarm algorithm is provided, the optimal charging current is calculated in each charging stage, and safe charging of the electric bicycle is achieved. According to the method, the objective function and the constraint conditions are established, the particle swarm optimization is adopted for searching the optimal charging strategy, the result is compared with a traditional constant-current and constant-voltage charging method, and the result shows that under the condition that the charging time is saved by about 27%, the battery is attenuated by only 0.03, and the temperature rise of the battery is within a safe and controllable range; therefore, the high efficiency of the method is verified.

    本发明涉及电池充电技术领域,具体为一种考虑充电安全的电动自行车充电方法及系统,包括,采用多段式充电方法对电动自行车进行充电;考虑每个充电阶段的充电限制,建立阶段性多约束的电池充电策略;提出多段恒流充电粒子群算法,在每个充电阶段计算最优充电电流,实现对电动自行车的安全充电。本发明通过建立目标函数和约束条件,采用粒子群算法进行搜寻最优充电策略,并将结果与传统的恒流恒压充电方法进行对比,结果表明在充电时间节省了约27%的情况下,电池仅多衰减了0.03,电池的温升也在安全可控的范围之内,从而验证了本发明方法的高效性。
