AI Technical Summary

Technical Problem

In the existing technology, the batteries of generator sets are prone to self-discharge and depletion when the generator is shut down for a long time, resulting in a decrease in battery capacity. This makes them unusable in situations without a grounding point, and they cannot be switched to an independent power supply mode, making them unsuitable for two-wire starter motors.

Method used

A battery control device was designed, comprising a changeover switch, a negative contactor, and a positive contactor. By setting different positions, it can realize power failure protection, independent power supply, and parallel power supply modes, thereby avoiding battery depletion and supporting use without a grounding point.

Benefits of technology

It effectively prevents battery depletion, improves the stability and safety of power supply, reduces maintenance costs, is suitable for various generator sets and vehicles, and is easy to install and disassemble.

Abstract

The utility model provides a storage battery control device for a generator set and a vehicle, and relates to the technical field of generator sets, and the storage battery control device comprises a first storage battery pack, a second storage battery pack, a cathode contactor, an anode contactor and a change-over switch. One end of the cathode contactor is connected with the cathode of the No.1 unit starting motor and the cathode of the No.2 unit starting motor, and the other end is connected with the cathode of the first storage battery pack and the cathode of the second storage battery pack. One end of the anode contactor is connected with the anode of the first unit starting motor and the anode of the first storage battery pack, and the other end is connected with the anode of the second unit starting motor and the anode of the second storage battery pack. The output end of the change-over switch is connected with the control end of the cathode contactor and the control end of the anode contactor. And when the change-over switch is located at the first gear, the negative contactor and the positive contactor are disconnected. The device can effectively prevent the storage battery from undervoltage, and regular starting of the generator set or external charging maintenance of the storage battery are not needed.
