The invention relates to a double-source trolley bus charging system and a control method thereof, and belongs to the technical field of double-source trolley bus charging. The method comprises the steps that in the static charging process, the whole vehicle makes a power request according to the allowable charging power of a battery, and the actual response power of an isolation DC/DC converter is collected in real time; when the actual response power exceeds the allowable charging power of the battery, calculating an error value between the actual response power and the allowable charging power of the battery; correcting the allowable charging power of the battery according to the error value, wherein the corrected allowable charging power of the battery is obtained by subtracting the error value from the allowable charging power of the battery before correction; the battery allowable charging power is updated to be the corrected battery allowable charging power at the next moment, and the whole vehicle makes a power request according to the updated battery allowable charging power; and carrying out normal charging until the actual response power is less than or equal to the battery allowable charging power. According to the invention, the condition that charging exceeds the limit is avoided, and the charging reliability is improved.
本发明涉及一种双源无轨电车充电系统及其控制方法,属于双源无轨电车充电技术领域。方法包括:静置充电过程中,整车按照电池允许充电功率进行功率请求,并实时采集隔离DC/DC变换器的实际响应功率;当实际响应功率超出电池允许充电功率,则计算实际响应功率与电池允许充电功率的误差值;根据所述误差值修正电池允许充电功率,修正后的电池允许充电功率为修正前的电池允许充电功率减去所述误差值;下一时刻更新电池允许充电功率为修正后的电池允许充电功率,整车按照更新后的电池允许充电功率进行功率请求;直至实际响应功率≤电池允许充电功率,进行正常充电。本发明避免出现充电超出限制的情况,提高了充电的可靠性。
