Problems solved by technology

When it is used as a load, the converted electric energy will be incorporated into the power grid, but due to the transient nature of the test conditions, the electric energy generated by it is not stable, and corresponding voltage stabilizing equipment is required to convert the generated unstable electric energy into stable electric energy and then merge it into the power grid. power grid
However, if it is directly connected to the power grid without a voltage stabilizing device, it will affect the entire power grid, thereby affecting the stability of the power grid

Abstract

The invention discloses a battery management-based multifunctional dynamic test system comprising an AC / DC module, an electric motor controller, a DC / DC module, a power battery, a battery management system, an electric power dynamometer and a dynamometer controller, wherein the DC / DC module is connected with the AC / DC module; the dynamometer controller is used for controlling and outputting A phase, B phase and C phase dynamic electricity; when being in a motored mode, the electric power dynamometer is used for converting electric energy into mechanical energy and is enabled to output rotating speed and torque; when being in a load mode, the electric power dynamometer is used for converting the mechanical energy output by an electric motor being tested into the electricity energy, and the power battery can be charged and / or electric power can be supplied to the electric power dynamometer. Via the test system, cyclic use of the electric energy can be realized without any voltage stabilizing device, energy saving effects of the system can be improved, and laboratory construction cost can be lowered.

Description

technical field [0001] The invention relates to the technical field of new energy bench testing, in particular to a multifunctional dynamic testing system based on battery management. Background technique [0002] In the process of automobile testing, bench testing is an indispensable link, and bench testing can be divided into steady-state testing and dynamic testing. The steady-state test mainly tests the steady-state performance of the system or components, and the functional verification test of the control system; the dynamic test refers to the transient test for the purpose of the experiment and regulations, and truly simulates the road driving conditions of the real vehicle. [0003] Energy saving, emission reduction, and green and efficient travel have become the main theme of today's society, and the focus of realizing efficient, energy-saving and green travel is the transformation of the power system. In addition to improving the combustion efficiency of the tradi...
