The invention aims to provide an electric engineering machine battery protection method, a thermal management system and an electric engineering machine so as to protect a battery when the electric engineering machine performs energy recovery. According to the relation between the allowable recharging power of the battery and the required braking power of the electric engineering machine, when the required braking power is small, one part of the recycled electric energy is input into the battery as the allowable recharging power, and the other part of the recycled electric energy is input into the energy consumption component for consumption, so that the situation that the recycled electric energy is input into the battery without limitation is avoided; and the battery is protected during energy recovery.

    本申请致力于提供一种电动工程机械电池保护方法、热管理系统和电动工程机械,以在电动工程机械进行能量回收时保护电池。根据电池的允许回充功率与电动工程机械的需求制动功率之间的关系,在需求制动功率较小时将一部分回收电能以允许回充功率输入电池,另一部分输入能量消耗部件进行消耗,避免将能量回收的电能无限制的输入电池,实现了能量回收时对电池的保护。
