Novel new energy bus constant-temperature heating control system

Abstract

The invention discloses a novel new energy bus constant-temperature heating control system. According to the novel new energy bus constant-temperature heating control system, intelligent heating and constant-temperature control are adopted, and the comfort degree of bus taking in winter is increased. The novel new energy bus constant-temperature heating control system comprises a high-voltage buspower supply, a DC / DC converter, a heating control unit, a temperature sensor and graphene heating floors. The novel new energy bus constant-temperature heating control system is characterized in thatthe high-voltage bus power supply is converted into a working power supply of the graphene heating floors through the DC / DC converter, the temperature inside a bus is detected through the temperaturesensor, and the heating control system receives a signal of the temperature sensor and a heating temperature preset value signal to start or stop heating of the graphene heating floors to keep the temperature of a carriage to be within a preset value.

Description

technical field [0001] The invention belongs to the technical field of heating for new energy passenger cars, in particular to a heating control system for pure electric buses. Background technique [0002] With the improvement of the country's economic level, people's requirements for the comfort of passenger cars are getting higher and higher, especially in winter in the north, it is necessary to heat the cabin and maintain a comfortable temperature. The existing pure electric bus heating control system generally adopts manual control by the driver, and the driver sets a certain air-conditioning power gear. The system is relatively simple, and it is impossible to intelligently heat and control the temperature according to the temperature in the car. [0003] In addition, the energy consumption of air-conditioning and heating systems cannot be ignored, which will reduce the battery life of pure electric buses and increase the number of outages for charging, thereby increasi...

Problems solved by technology

The existing pure electric bus heating control system generally adopts manual control by the driver, and the driver sets a certain air-conditioning power gear. The system is relatively simple, and it is impossible to intelligently heat and control the temperature according to the temperature in the car.

[0003] In addition, the energy consumption of the air-conditioning and heating system cannot be ignored, which will reduce the battery life of pure electric buses and increase the number of outages for charging, thereby increasing operating costs
