KersTech is a post-transmission, parallel hybrid retrofit system incorporating a high efficiency Kinetic Energy Regeneration System (KERS), often called “regenerative braking”, that is particularly suited for installation on existing, heavy Diesel engined vehicles that represent large capital expenditure and have long operational lives.

Hybrid vehicles are most fuel efficient in frequent start-and-stop drive cycles where electric- or hydraulic-powered launch and acceleration assist or replaces the Diesel engine's inefficient low speed operating range, while frequent braking and deceleration events provide multiple energy recovery opportunities.

Heavier vehicles benefit most from a hybrid retrofit conversion that reduces fuel consumption and exhaust emissions, and reduces brake wear because a large portion of the vehicle's kinetic energy that is normally dissipated as heat (due to brake friction) passes through the recovery system and is converted to stored energy for future use.

KersTech’s mechanical architecture enables Large Diameter, Flat-Format (LDFF) electric or hydraulic motors to be located post-transmission in the vehicle driveline via a patent pending integrated 90° gearbox configuration, without major chassis or frame modifications. The LDFF design permits optimum use of limited driveline space, enabling simplified and affordable hybrid conversion. The large diameter motor provides higher efficiency and greater torque without multi-ratio reduction gearing, minimizing cost, weight and complexity. The KersTech electric-hybrid retrofit can include plug-in battery charging to extend operating range.

The KersTech patent pending autonomous hybrid controller technology enables fast, non-invasive installation and optimal energy efficiency in all operating conditions.
