Kinetic Energy Recovery System
Our solutions for regenerative braking and traction, commonly known as KERS, can be tailored to the vehicle and operator’s needs.
Standard recovery systems can be installed on any semitrailer, however, in order to achieve the highest energy efficiency, we encourage our customers to audit the energy requirements of their routes to have optimised control systems.
Reduced fuel consumption
Up to 30% fuel savings, depending on driving cycle and optimisation of control system.
Reduced maintenance costs
Improve life of braking system and transmission components.
Lower tax on emissions
Your fleet can benefit from tax cuts due to lower emissions, depending on the local legislation.
How does it work?
A KERS requires no external charging, and hence, there is no required investment in infrastructure at your depot. This solution improves the energy yield of each litre of diesel that is used by the combustion engine on the tractor vehicle. It does so by working in two different modes: regenerative and traction.
Regenerative mode is activated during braking. The KERS transforms part of the vehicle’s kinetic energy, that would otherwise be lost as heat, into useful electric energy. This electric energy is stored in ultracapacitors that offer high speed charge and discharge, as well as higher cyclability than other energy storage solutions (i.e. Li-Ion batteries). These features make ultracapacitors the ideal technology for start-stop applications.
On traction mode, the system can deliver additional torque during vehicle acceleration. This allows the diesel engine to work within its optimum operating window. The control algorithm enables the system to reduce the internal combustion engine transients, leading to a reduction in total fuel consumption of 15 – 25%, depending on the drive cycle and route.
