Undervoltage protection system of parking air conditioner and vehicle

Abstract

The invention relates to the technical field of parking air conditioners, in particular to an undervoltage protection system of a parking air conditioner and a vehicle. The invention aims to solve the problem of untimely undervoltage protection existing in the existing parking air conditioner. For this purpose, the undervoltage protection system of the present invention includes a motion sensor and an electric control switch. The motion sensor is arranged on the ignition switch of the vehicle and is connected with the main control board. The sensor is configured to transmit an electrical signal to the main control board when an ignition action is detected, and the main control board is configured to control the electric control switch to be turned off based on the electrical signal. Through the above arrangement, the undervoltage protection system of the parking air conditioner of the present application can effectively protect the parking air conditioner from undervoltage, improve the operation safety of the parking air conditioner, and prolong the service life of the driving board of the parking air conditioner.

Description

technical field [0001] The invention relates to the technical field of parking air conditioners, in particular to an undervoltage protection system of a parking air conditioner and a vehicle. Background technique [0002] With the development of the transportation industry, parking air conditioners are installed in transport trucks, RVs, and buses. Compared with traditional automotive air conditioners, parking air conditioners do not need to be started by the vehicle engine, but are directly driven by the vehicle battery. It is a more energy-saving and environment-friendly air conditioner when the car is turned off. [0003] Since the power supply used by the parking air conditioner is the battery equipped with the vehicle itself, the output voltage of the battery will gradually decrease as the power decreases due to the limited battery capacity. If the driver starts the vehicle with the ignition on when the parking air conditioner is running, the voltage supplied to the pa...
