Electric handling equipment mutual support battery device

Abstract

A mutual backup battery device for electric handling equipment includes at least two batteries, each with an independent power switch, and a unidirectional conductive diode located at the output terminal of each battery. When electric handling equipment, including electric lifting trolleys, electric carts, electric stackers, and manual forklifts, performs quick battery swapping operations, the mechanism of alternating switching between the two batteries ensures that the precision electronic main unit is always powered, avoiding damage to the precision electronic main unit and other equipment caused by frequent power-on and power-off cycles. It also eliminates the need for signal calibration, zeroing, and homing procedures required after restarting the precision electronic main unit and other equipment, significantly improving operational efficiency and extending equipment lifespan. Furthermore, this device is equipped with a voltage display, allowing operators to monitor the battery status in real time and perform battery swapping operations as needed.
