Abstract

An electric power system for charging a power supply includes a detection unit and a control unit, the detection unit includes a current detection unit, a temperature sensor and a humidity sensor, thetemperature sensor mainly checks the temperature of the AC / DC converter, the humidity sensor mainly detects the humidity of the environment in which the AC / DC converter and an accumulator are located, and the current passing through the detection unit is turned off by a control unit, thereby protecting the transmission itself, and the current detection unit comprises a current detector and an alarm. As that current detector is arrange, facilitates adjustment of the battery charging current range, The signal transmission unit transmits the current signal passed through the ammeter to the CPU after being converted by an AD converter, and adjusts the magnitude of the conversion resistor by controlling the PCB, thereby adjusting the magnitude of the current in the circuit through detecting the magnitude of the current in the path by the ammeter connected in the circuit.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a power system for power supply charging. Background technique [0002] The power system is a whole composed of power plants, transmission grids, distribution networks and power users, and is a unified system that converts primary energy into electrical energy and transmits and distributes it to users. When the power system charges the power storage equipment used by the user, it is only directly connected to the power supply through the plug, without protecting the electrical equipment and transmission lines, which is likely to cause waste of electricity in the power system and damage to the power system. [0003] Therefore, it is necessary to invent a power system for charging a power source to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to provide a power system for charging a power supply. The current size in the path is...
