Embodiment Construction

[0021] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0022] In Fig. 1, a power electronic switch 5 is provided between the positive and negative poles of the power battery pack 10 and the DC bus 9 to control whether the power battery pack is connected to the DC bus. The power electronic switch is a controlled component, and its on-off is determined by the vehicle energy management and drive control strategy.

[0023] In Fig. 1, an energy consumption braking switch 6 is provided between one end of the energy consumption braking resistor 7 and the DC bus 9 to control whether the frequency converter 18 and frequency converter 2 21 discharge to the energy consumption braking resistor. The dynamic braking switch is a controlled component, and its on-off is determined by the DC bus voltage and the withstand voltage of the two inverters.

[0024] In Fig. 1, the engine 11 eliminates the conventional starter motor...

Abstract

The present invention discloses one kind of integrated power platform for mixed power vehicle, and belongs to the field of energy management technology for mixed power vehicle. The optimally designed integrated power platform consists of one chopper, three inverters, one power electronic switch, power consumption braking switch, one power consumption braking resistor, one integral rectifying and inversing device and one DC bus. The integrated power platform has high power efficiency, good heat dissipating effect and light weight, and is favorable to space arrangement and power source cooling in vehicle.

Description

Technical field [0001] The present invention belongs to the technical field of Energy Management System (EMS, Energy Management System) of Hybrid Electric Vehicle (HEV), and particularly relates to the Integrative Power Supply (IPS, Integrative Power Supply) technology of hybrid electric vehicles. More specifically, the present invention An integrated power control platform for hybrid vehicles is proposed, which is suitable for hybrid vehicles such as buses and military tracked vehicles that adopt hybrid power systems. Background technique [0002] In order to cope with increasingly stringent environmental regulations worldwide and the future shortage of petroleum resources, electric vehicle (EV) technology has become one of the most promising technical fields in the field of vehicle engineering (VE, Vehicle Engineering). Compared with pure electric vehicles (EV, Electric Vehicle) and fuel cell vehicles (FCEV, Fuel Cell Electric Vehicle), hybrid electric vehicles have become the ...
