EP1

The Electric Powertrain (EP1) from Punch Powertrain is a complete drive system for electric vehicles that was developed on the basis of a Permanent Magnet Motor. This is the first electric drivetrain in Punch Powertrain’s EV drives portfolio, which is currently in the stage of mass production.

Lighter, smaller, quieter

Integrating the Electric Motor and the single speed transmission into an integrated powertrain with reduced number of wearing parts, renders it substantially smaller and lighter. Moreover, extensive adaptations to its housing give the system more rigidity and improve its acoustic performance.

Wide applicability

The EP1 is offered in 2 main variants: EP1-P for passenger cars and EP1-C for light commercial vehicles. Both products operate with the same e-motor, while the difference lies in the gearbox design. EP1-P has a configurable gearbox ratio of around 10:1, while the EP1-C operates with a fixed ratio of 16:1 and an enforced Park-mechanism.

Dynamic driving behavior

In the test vehicles the EP1 demonstrated its possibilities for dynamic driving behavior and high power output. The electric motor achieves a 90kW power (46kW continuous) output and a wheel torque of 2600Nm. Maximum speed depends on the vehicle’s characteristics including wheel size and ranges between 130 and 170 km/h.
