Electric heat-storage heating equipment of electric bus

Abstract

The invention relates to the technical field of heating of buses, in particular to electric heat-storage heating equipment of an electric bus. The electric heat-storage heating equipment comprises an air return box, a heat storage box, an air supply box and an electricity supply mechanism. In the electric heat-storage heating equipment, cold air in the bus is led into the air return box through an air return opening in the bus and then input into the heat storage box to be heated; the heated hot air is led into the air supply box through the heat storage box, and the air supply box leads the hot air into the bus through an air supply opening in the bus for heating; and meanwhile, the electricity supply mechanism supplies electricity, so that the electricity quantity of a vehicle-mounted accumulator in the bus is not occupied, and the endurance mileage of the bus is also guaranteed while heating is guaranteed.

Description

technical field [0001] The invention relates to the technical field of bus heating, in particular to electric heat storage heating equipment for electric buses. Background technique [0002] With the rapid development of electric vehicles, the guidance of government policies, and the low operating cost of electric vehicles, the number of electric buses in cities has increased rapidly. [0003] As we all know, electric buses use the on-board battery as the power source for the operation of the car; and at this stage, there are generally three ways to heat electric buses in winter: electric heaters, heat pump air conditioners, or on-board oil-fired boilers plus hot water radiators in the car; the first two All heating schemes are electric heating, and the power supply is completed by the on-board battery of the electric vehicle. During the operation of the vehicle, in order to ensure the heating demand in the car, more than 30% of the electricity in the on-board battery will b...

AI Technical Summary

Problems solved by technology

In order to solve the above heating problems, some electric buses are equipped with on-board oil-fired boilers and in-vehicle hot water radiators for heating. Due to the low efficiency of small oil-fired boilers, the heating operation costs are high, and at the same time, the combustion is not sufficient, and pollution is generated during the oil combustion process. The gas in the environment is contrary to the original intention of the use of new energy electric vehicles, and it is not conducive to the sustainable development of electric vehicles. It is a last resort
