A specific environment
To test the complete vehicle, electric motors have changed many things. For the most part without a gearbox and with a torque available from zero speed, the chassis dynamometer or the hub dynamometer must be able to withstand these strong constraints.
For example, +10000N force could be applied on some electric supercars !
It’s much more than the usual sport cars !
The needs of a vehicle test are also very different from one project to another that is why we have a standardized offer as well as project answers based on your specifications.
In particular, the loading machine (s) can be adjusted to provide more or less torque and more or less power.
