Problems solved by technology

The advantages of the new energy bus are: the fuel consumption is significantly reduced, and the emission can reach the National IV standard. The disadvantage is that the battery capacity and life are still insufficient
If the existing bus air conditioner is installed on the new energy bus, it will seriously affect the mileage of the new energy bus
In addition, hot water can be used for heating by the air conditioner of the existing bus, but it is not advisable to use hot water for heating in new energy buses due to the small heat generated by the motor

Abstract

The invention discloses a frequency conversion and energy saving electric control assembly used for a new-energy electric passenger vehicle alternating and direct current air conditioning system. The frequency conversion and energy saving electric control assembly is provided with a compressor frequency converter, a power converter, a vehicle-mounted power double-security wire holder, a deconcentrator, a wiring terminal strip and a PLC. The output side of the PLC is connected with a control terminal interface on the compressor frequency converter. The input side of the PLC acquires pressure protection information, temperature information, compressor thermal protection information and frequency converter fault acquisition information in the electric air conditioning system. The compressor frequency converter is electrically connected with the deconcentrator and a compressor. The frequency conversion and energy saving electric control assembly has the beneficial effects that the assembly is provided with the PLC and has the function of communicating with a whole vehicle CAN, the function of automatic frequency conversion control over the compressor, the function of automatic speed adjustment control over a draught fan and the function of control over heating of a heat pump and heating of a PTC, and the assembly is suitable for conducting frequency conversion control on the electric air conditioning system of the alternating current compressor and the direct current draught fan and capable of being applied to the air conditioning system of an electric passenger vehicle with the length ranging from 7 m to 12 m.

Description

technical field [0001] The invention relates to the related technical field of circuit equipment, in particular to a frequency conversion and energy-saving electric control assembly used in an AC / DC air conditioning system of a new energy electric passenger car. Background technique [0002] With the development of science and technology and the increasing scarcity of oil resources, new energy vehicles have gradually entered thousands of households, and new energy electric buses are an important part of new energy vehicles. [0003] New energy buses mainly refer to: diesel-electric hybrid buses (accounting for more than 90% of new energy buses in my country), pure electric buses, fuel cell buses, etc. (new energy buses under study should also include natural gas buses, liquefied natural gas buses , liquefied petroleum gas bus, alcohol fuel bus, super capacitor bus, etc.). The advantages of the new energy bus are: the fuel consumption is significantly reduced, and the emissio...
