Equipmake Holdings plc has signed a technology agreement with Hillcrest Energy Technologies
to develop an 800-volt traction inverter for heavy-duty electric vehicles.

The agreement combines Hillcrest’s Zero Voltage Switching (ZVS) technology with 
Equipmake’s electric drivetrain engineering and manufacturing capabilities. The 
companies will target electric trucks, buses, coaches and specialist off-highway
vehicles used in construction, agriculture, mining and industrial applications.

The technology is designed to reduce electrical losses, improve inverter efficiency
and lower electromagnetic interference. These improvements could help extend vehicle
range, reduce operating costs and improve the performance of electric powertrains.

Hillcrest’s ZVS technology has achieved peak inverter efficiency of 99.7% during
laboratory testing. Separate testing has also demonstrated a reduction of more than
90% in motor-terminal voltage overshoot.

The development programme will involve two prototype stages, each subject to agreed
technical performance requirements. The companies aim to finalise the technical 
specification and resource plan within six months.

Equipmake will provide engineering staff, testing facilities and its experience 
in powertrain integration and manufacturing. Hillcrest will contribute its ZVS technology
and technical expertise.

If the final prototype meets the agreed acceptance criteria, Equipmake will receive
exclusive worldwide manufacturing and sales rights for the licensed technology in
the specified vehicle markets. The initial exclusivity period will last six years,
subject to annual minimum sales targets.

The agreement covers heavy commercial trucks, buses, coaches and off-highway equipment,
but excludes passenger vehicles.
