• The ZES is coupled through the vehicle’s existing PTO port.

  • We exploit the vehicle’s OEM drivetrain to propel it in 100% electric mode up to 24 MPH (can be adjusted to fleet drive cycle).

  • THE OEM ENGINE IS COMPLETELY TURNED OFF.

  • The ZES is designed to accommodate the engine’s accessory and driver comfort systems.

  • At speeds above 24 MPH (can be adjusted to fleet drive cycle), the system automatically re-starts the diesel engine and transitions driving power requirements to it.

  • The battery is recharged utilizing the electric motor and regenerative braking system. Rapid recharge within OEM operation.
