Tevva Motors road tests zero emission trucks

Smart software controls range extender powertrain to improve battery life

Tevva Motors has developed an electric range extended drivetrain for trucks that has the ability to reduce or avoid producing emissions using its intelligent predictive software.

UK road tests of three of its zero emission trucks for back-to-base fleets are currently under way, one of which is in daily use with logistics operator UPS.

The electric range extender powertrain can be fitted into an existing 7.5 tonne truck, either as a retrofit package or on the production line during the build process.

Consisti of a single 120kW electric motor, the drivetrain is capable of producing 1800Nm (1325 lb ft) from zero rpm, powered by 66kWh batteries located on the chassis. The drivetrain also has a range extender unit, which uses a small capacity diesel engine to generate additional charge while on the move.ng

The complete drivetrain is controlled by Tevva’s patent pending Predictive Range Extender Management System (PREMS). The system operates in real-time to analyse NOx and air quality data and GPS navigation.

The vehicle is then able to decide when to use the range extender, for example during 'high discharge' situations on motorways, and when to avoid use, such as in poor air quality areas like towns and cities. This ensures the maximum use of battery charge is made on every journey.

Asher Bennett, Tevva Motors chief executive officer, said: “Tevva’s electric range extender technology removes the operational risk created by pure electric vehicles, allowing unlimited operational range, but typically spending the majority of a day’s operations on electric only.

"Our proprietary technology enables smart use of the range extender; fleets get the maximum use from the battery power, delivering full low emission benefits and cost savings.”
