Just building an electric drivetrain and tuning performance ‘on the road’ will never get you maximum performance and efficiency results. Using our EV power meter will give you valuable insights upfront. Our Power Battery power meter is a dynamometer which measures torque and rotational speed (RPM), in order to maximize the performance of your electric drivetrain.
Test your EV drivetrain
The drivetrain of an electric vehicle (EV) is especially important. The range of an electric vehicle is often less than the range of a vehicle with combustion engine, therefore efficiency is of the essence when designing an EV drivetrain. When a drivetrain is placed in an application, it often isn’t as efficient and/or powerful as it could be. Access to a proper test setup, before assembling the drivetrain and placing it in your vehicle is crucial when you want to optimize your EV solution.
We have created a solution to optimise an EV drivetrain. We have built a custom power meter you can mount your drivetrain on and test it to its maximum. You can make changes in the controller and immediately see the result of the change. In a relatively short period of time, you can test the drivetrain and adjust it where needed. Afterwards, your drivetrain is ready to be built into the vehicle. No more adjustments need to be made ‘on the road’.
How does the EV power meter work?
There is a frame where the drivetrain needs to be mounted. We can provide a mounting plate upon request for your drivetrain or you can bring your own.
- The drivetrain is connected to the brake with a flexible coupling so the shaft of the drivetrain cannot be damaged.
- The controller and battery pack can be placed on a workbench nearby. The drivetrain is now in place.
- When a cooling system is present for the drivetrain, we have also the possibility to cool it with driving wind. We have a fan that can reach an airspeed of 120 km/h.
- When all the components are in place, the testing of the drivetrain begins. In the power meter the maximum rpm and torque need to be set. The power meter has a brake torque up to 800 Nm and a maximum rpm of 6500 rpm.
- We test the drivetrain within its limits.
The power meter has a manual mode and dyno mode. In the manual mode the brake can be controlled manually. In this mode the drivetrain can be configured until it operates correctly. A detailed measurement of the performance of the drivetrain can be performed by the ‘dyno mode’. In this mode, the drivetrain ramps up from 0 rpm to the maximum rpm with a certain brake power. This brake power is adjustable. The result is a graph of the torque and power that the motor delivered during the ramp up.
Our power meter service packages
Tuning your drivetrain
You deliver the complete drivetrain with a mounting plate for the engine. This is an already well-running drivetrain, but you want to know how much torque and power the drivetrain generates.
Debugging and adjusting
You deliver the complete drivetrain with a mounting plate for the engine. This drivetrain doesn't yet run very well. Adjustments need to be made.
Complete configuration
You deliver the complete drivetrain without a mounting plate for the engine. This drivetrain doesn't run at all. The drivetrain needs to be configured completely.
Setting up a new drivetrain
You have no drivetrain. Power Battery chooses a drivetrain according to your specifications. The drivetrain is fully tested and will be delivered as a fully functioning drivetrain with test reports. You only need to mount it in the application.
