Embodiment Construction

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

[0022] figure 1 Among them, 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] figure 1 Among them, a dynamic braking switch 6 is set between one end of the dynamic braking resistor 7 and the DC bus 9 to control whether the frequency converter 1 18 and the frequency converter 2 21 discharge to the dynamic braking resistance. 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 frequency converters.

[0024] figure 1 Among them, the engine 11 cancels ...

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 the energy management system (EMS, Energy Management System) of the hybrid electric vehicle (HEV, Hybrid Electric Vehicle), particularly relates to the integrated power supply (IPS, Integrative Power Supply) technology of the hybrid electric vehicle, more precisely, the present invention An integrated power supply control platform for hybrid electric vehicles is proposed, which is suitable for hybrid electric vehicles such as buses and military tracked vehicles with hybrid electric systems. Background technique [0002] In order to cope with the increasingly stringent environmental protection regulations worldwide and the future shortage of oil resources, electric vehicle (EV, Electric Vehicle) 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 vehi...
