Vehicle-used hybrid energy storage control system based on dSPACE and motor test bench

Abstract

The invention discloses a vehicle-used hybrid energy storage control system based on dSPACE and a motor test bench. The vehicle-used hybrid energy storage control system comprises a dSPACE-based energy management controller, the vehicle-used motor test bench, a power battery pack, a power battery management module, a supercapacitor bank, a supercapacitor management module, and a bidirectional DC / DC direct current transformer, wherein the dSPACE-based energy management controller is connected with the power battery management module, the supercapacitor management module, the bidirectional DC / DCdirect current transformer and a tested motor controller on the vehicle-used motor test bench; and one end of the bidirectional DC / DC direct current transformer is connected with the supercapacitor bank, and the other end is connected with the power battery pack and a DC power supply terminal of a tested motor. The vehicle-used hybrid energy storage control system can implement various energy management control strategies simply and flexibly, and is convenient for testing energy utilization efficiency and energy distribution among various energy storage devices by means of the energy management controller under various typical operating conditions.

Description

technical field [0001] The invention belongs to the field of automotive electronics, in particular to a vehicle hybrid energy storage control system based on dSPACE and a motor test bench. Background technique [0002] Nowadays, environmental pollution and energy shortage are huge problems faced by all countries in the world. Electric vehicles are becoming more and more popular due to their green and environmental protection features. In addition, governments of various countries have introduced preferential policies, which has attracted major automobile manufacturers to invest a lot of money. Develop technologies related to electric vehicles. [0003] Due to its high energy density, power batteries have become the main energy storage medium for electric vehicles. Its main disadvantages are short cycle life, long charging time, and narrow temperature range. On the other hand, supercapacitors have high power density, can provide instantaneous high current, and have very sho...

AI Technical Summary

Problems solved by technology

For the former category, no matter how the model is established, it has its limitations, uncertainties, and incompleteness.

For the latter category, if you want to implement different algorithms and compare the pros and cons of each control strategy for the control strategies implemented on the MCU / PLC, you need to go through steps such as code modification, code debugging, and actual vehicle testing. This process on / PLC is very complicated and takes a considerable amount of time

On the other hand, after the controller is designed, it needs to be tested on a real vehicle, which is costly and difficult to guarantee safety.
