On-off control method of engineering machinery storage battery relay, electronic terminal and storage medium

The invention discloses an on-off control method of an engineering machinery storage battery relay, an electronic terminal and a storage medium in the field of engineering machinery control. The method comprises the following steps: judging the running state of engineering machinery according to collected engine rotating speed information; if the operation state is an operation state, or the operation state is a shutdown state and is in a power-on state at the same time, and a storage battery relay delay disconnection instruction is not received, the current power-lack state of the storage battery is judged according to the current voltage value of the storage battery; and if the current power-lack state of the storage battery is that the storage battery does not lack power at present, controlling the storage battery relay to be closed. The safety of the whole vehicle and the durability of the storage battery can be protected, and power supply of the storage battery is facilitated. 本发明公开了工程机械控制领域的一种工程机械蓄电池继电器
