48 inch car chassis dynamometer - meet the vehicle multi-drive mode

The purpose of the system is to use a chassis dynamometer and a single axis controller with dual support motor function for vehicle power performance, economic performance testing, and emission testing. The system uses an AC electric dynamometer, which can simulate road resistance with full electrical inertia on the basis of the inherent mechanical inertia of the chassis dynamometer, and can reproduce the road driving resistance of the tested vehicle or customize road resistance, The system is a brand new automotive testing system designed and developed independently in accordance with national standards and European and American certification regulations, with independent intellectual property rights. Development of external communication protocol interfaces for the system, which can expand multiple external interfaces and interface with various electric energy testers, emission analyzers, fuel consumption testers, etc., to achieve real-time monitoring of automotive testing parameters and the implementation of domestic and foreign testing cycle routes. It can also be upgraded according to user requirements to meet the testing requirements of other national standards.
