Multifunctional hybrid power general test stand and test method

Abstract

The invention discloses a multifunctional hybrid power general test stand and a test method, relating to the hybrid power test field. The multifunctional hybrid power general test stand consists of an engine, a coupler, an ISG motor, a speed changer, a motor, a sensor, a power synthesis device, a sensor, a dynamometer, an inertia device, a brake, an engine ECU, a rectification inverter, a battery-super capacitor energy driving system, a general control system consisting of controllers of all parts and a CAN bus, and a monitoring control computer. The test device can simulate the most of the operation conditions of the hybrid vehicles, provides a test platform for the development of the hybrid vehicle multi-energy-source control and the regenerative braking function and can provide and finish the various performance tests related to the hybrid power vehicle through changing the mutual connection modes between various members of the device and the control modes of various members.

Description

technical field [0001] The invention relates to the technical field of hybrid power testing, and more specifically relates to a multifunctional hybrid power comprehensive test bench and a testing method thereof. Background technique [0002] At present, the problems of energy shortage and environmental pollution are becoming increasingly prominent, so reducing dependence on fossil energy and reducing environmental pollution are the current top priorities. Developing hybrid vehicles and reducing exhaust emissions is one of the effective means to solve this problem. As a new energy vehicle, hybrid vehicles have broad development prospects. They combine the characteristics of traditional internal combustion engine vehicles and pure electric vehicles. Taking into account power and environmental protection. For the two power sources of hybrid electric vehicles, although the existing hybrid experimental device can meet certain test requirements, there are still some limitations, ...
