Embodiment 1

[0023] Embodiment 1: A bench test system for a distributed energy supply system, its circuit principle connection diagram is as follows figure 1 As shown, it includes a platform, which is equipped with a power follower group 1, a fuel supply and collection system 2, a drive system control system 3, a drive system 4, a battery simulator system 7, and a distributed system energy management unit 9. The bench test system of the type energy supply system also includes a test load 5 and a test load control system 6. Several power followers 11 are arranged in the power follower group, and each power follower is equipped with a power follower energy management unit. 111, several power follower energy management units are connected through the CAN bus, the test load and the test load control system are connected through the CAN bus, the fuel supply and collection system, the drive system control system, the drive system, the test load control system, The battery simulator system and th...

Embodiment 2

[0029] Embodiment 2, a bench test system for a distributed energy supply system, its principle and implementation method are basically the same as in Embodiment 1, the differences are as follows figure 2 As shown, a power analysis device is also included, and the power analysis device is connected to the CAN bus. Step 3 also includes synchronous real-time collection of efficiency data of the drive system and power follower group by the power analysis equipment, and the efficiency data is sent by the distributed system energy management unit to the test load control system for recording through CAN bus communication.

[0030] When the drive system control system has an overspeed alarm, the speed signal sent by it is received by the energy management unit of the distributed system, and the emergency stop processing signal is fed back to the drive system control system and power follower through its pre-set control logic The energy management unit also feeds back to the fuel sup...

Abstract

The invention discloses a rack testing system and a rack testing method for a distributed energy supplying system. The rack testing system comprises a rack on which a power follower set, a fuel supplying and acquiring system, a driving system control system, a driving system, a battery simulator system and a distributed system energy management unit are arranged. The rack testing system for the distributed energy supplying system further comprises a testing load and a testing load control system. The power follower set is internally provided with a plurality of power followers. Each power follower is internally provided with a power follower energy management unit. The rack testing system and the rack testing method for the distributed energy supplying system can supply accurate and effective testing on energy supplying to double range extenders, multiple range extenders and a power battery, thereby obtaining true and effective testing data and effectively supporting a whole-vehicle matching and control algorithm.

Description

technical field [0001] The invention relates to the field of automobile performance testing, in particular to a bench testing system and testing method of a distributed energy supply system. Background technique [0002] Vehicles powered by hybrid energy are transitional vehicles between traditional vehicles and vehicles powered by pure power batteries, which have some advantages of traditional vehicles and vehicles powered by pure power batteries, such as low emissions, high efficiency and Long battery life, etc. Vehicles powered by hybrid energy currently on the market mainly use a single range extender and a single power battery to jointly provide energy supply. [0003] However, in the test method for hybrid energy-driven vehicles, it is not possible to build a test framework for dual-range extenders or multi-range extenders and their control systems, and the vehicle models that cannot match the actual situation can be used as the main object of the system test. During ...
