Automatic charging and discharging device

Abstract

The invention relates to the technical field of charge and discharge monitoring, in particular to an automatic charge and discharge device, which comprises a load, a charge and discharge unit connected with the load and a power supply respectively, an electric power storage unit connected with the charge and discharge unit, and a hydrogen evolution sensor connected with the electric power storage unit and the charge and discharge unit respectively, wherein the charging and discharging unit comprises a power supply module, a charging module and a main control board, the voltage and current conditions of the charging and discharging unit for the ship are monitored in real time, an audible and visual alarm can be given out when a circuit breaks down, the two rectifying modules are arranged in the charging and discharging unit, the two loops are used alternately, and the service life of the circuit is prolonged. A complete monitoring and guaranteeing system is provided for the electric power storage unit, the charging and discharging device can monitor the hydrogen concentration of the electric power storage unit, when the hydrogen content of the cabin exceeds a set value, the charging and discharging device gives an alarm and stops charging of the storage battery, and when the storage battery is in a charging state, an in-cabin ventilator is automatically started; therefore, the power storage unit is ensured to be at a proper working temperature.

Description

technical field [0001] The invention relates to the technical field of charge and discharge monitoring, in particular to an automatic charge and discharge device. Background technique [0002] At present, in the shipbuilding industry, the charging and discharging board is a necessary electrical equipment. During the sailing process of the ship, if the AC power supply is normal, the DC 24V power supply is generated by step-down and rectification, which is used for the equipment on board, and the battery is charged at the same time. Once the AC power supply fails, the battery power supply is automatically connected, and when the AC power supply is restored, the battery is automatically cut off. [0003] The step-down rectification process of the marine charging and discharging board is a very important link in the charging and discharging board circuit, and it is used very frequently. It is very important to control and monitor the working condition of the charging power suppl...
