The whole power system of the utility model adopts a unified power platform of new multi-energy resources buses with the double motors and the double energy controlling units, and the multi-power supplies and the double motors with the parallel power combination in the single output way, to quicken the research and development progress, and to save the development cost.
Description
Technical field
The utility model relates to a kind of power system of hybrid electric urban bus, especially a kind of pure electric coach, super capacitor passenger vehicle, fuel cell hybrid car, and the power system of serial mixed power passenger vehicle.
Background technology
Along with quickening of urbanization process, the auto-industry fast development, bring easily simultaneously bringing wealth and people's lives to society, also bring serious environmental to pollute and energy resource consumption thereupon, particularly the growth rate of self-propelled vehicle is higher than the urban traffic network construction speed in recent years, traffic jam issue is serious day by day, in this case, bus as the city traffic main force stops and goes, driving slowly, driving engine is often run under the operating mode of low efficiency maximum discharge all the time, therefore bring very big coverlay influence to the city.In Shanghai, only account for automobile pollution less than 10% taxicar (recoverable amount is 40,000) and bus (nearly 20,000), its blowdown flow rate accounts for more than 50% of motor vehicle exhaust emission total amount, simultaneously city bus is more because its alignment, regularly, the characteristics of centralized management are easier to carry out the new forms of energy strategy.Actively develop the demonstration operation of new-energy automobile, when strengthening public's environmental consciousness, representing city image, more likely become the breach of new-energy automobile development, popularization and industrialization.
The new forms of energy scheme of passenger vehicle mainly contains substitute fuel scheme, pure electric automobile (EV) scheme, fuel cell electric vehicle (FCEV) scheme and hybrid power scheme at present, although but back three kinds of schemes have general character, but concrete scheme is various informative, at this present situation, need a kind of power system of platform design altogether, be used to accelerate the research and development progress, save cost of development.
Summary of the invention
The utility model will provide a kind of and can realize, the hybrid electric urban bus of the multiple preferably new forms of energy passenger vehicle of reliability is the power system of platform design altogether, to accelerate the research and development progress, saves cost of development.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of hybrid electric urban bus is the power system of platform design altogether, comprise motor, the energy control unit, distribution equipment, entire car controller is characterized in: power system is made of double-motor, dual energy control unit, double-motor is connected to form power in parallel with the energy control unit respectively and synthesizes, and be connected with distribution equipment, distribution equipment is connected in parallel by the DC/DC and the secondary energy storage device of energy control unit, and distribution equipment provides electric energy for motor and attached high-pressure system and DCL jointly.
Entire car controller connects power control unit, and transmits control signal by the mode of CAN communication to power grip.
Power grip comprises electric machine controller secondary energy storage device, auxiliary net; The secondary energy storage device comprises storage battery, super capacitor; Attached high-pressure system comprises oil pump, Air compressor, water-cooling system.
The beneficial effects of the utility model are: provide a unified power platform design plan at fuel cell hybrid passenger vehicle, super capacitor passenger vehicle, serial mixed power passenger vehicle, pure electric coach.Be the unified power platform that whole power system adopts the synthetic single multiple new forms of energy passenger vehicle of exporting of power in parallel of double-motor, two PCU (power control unit), multi power source, double-motor, can accelerate the research and development progress, save cost of development.
