The invention discloses a motor braking energy consumption control method and system and an automobile crane, and the method comprises the steps: when obtaining a deceleration braking state of an upper vehicle motor during upper vehicle operation, judging whether the braking current of an upper vehicle electric system is greater than the preset recharging current of a power battery system; if the braking current of the on-board electric system is not larger than the preset recharging current of the power battery system, the power battery system recycles the braking current; and if the braking current of the boarding electric system is greater than the preset recharging current of the power battery system, starting a resistance braking system and/or a thermal management system to consume energy according to the difference value between the braking current of the boarding electric system and the preset recharging current of the power battery system, and ensuring normal deceleration braking of a boarding motor of the truck crane.
本发明公开了一种电机制动能量消耗的控制方法、系统及汽车起重机,该方法包括:当上车作业,获取上车电机减速制动状态时,判断上车电动系统的制动电流是否大于动力电池系统预设回充电流;若上车电动系统的制动电流不大于动力电池系统预设回充电流,动力电池系统回收制动电流;若上车电动系统的制动电流大于动力电池系统预设回充电流,根据上车电动系统的制动电流与动力电池系统预设回充电流的差值,开启电阻制动系统和/或热管理系统消耗能量,确保汽车起重机的上车电机正常减速制动。
