72" Chassis Dynamometer for Heavy-Duty Commercial Vehicles

Electric vehicles (FCEV, HEV, PHEV) multi functional testing purposes such as battery efficiency within climatic chamber (complex environment), mileage accumulation, endurance and performance

Chassis dynamometer having world class control algorithms coupled with innovative mechanical designs and integration technology has been completely developed over the acquisition period by TeSys for Hofmann TeSys GmbH and Froude Hofmann chassis dynamometer product IP from 2016 up to 2018.  Now, TeSys can present a strong platform for the compete range of chassis dynamometer products contributable to Research and Development purpose with configurable versions for Battery Efficiency (PHEV, HEV, BEV), Emission, Performance/Endurance,Climatic, NVH and other bespoke applications to suit military, heavy/medium/light duty vehicles as well as motorcycle / AGV / ATV / 2-wheelers. Our chassis dynamometer has multiple solutions from a simple 1 wheel drive motorcycle to a fully independent 16x16 special commercial vehicle system applicable to conventional and e-drive vehicles.

TeSys chassis dynamometer for heavy-duty-vehicles (HDV) are manufactured for tests requiring high torque response and also capable of axle loads up to 30,000 kg while steadily providing repeatable and reliable test results with a realistic tire rolling performance and suitable for vehicles with dual and single rear tires.
