Hessner is leading the way in developing intelligent and augmented energy utilisation for last-mile transportation. Our power management system (PMS) and high power density supercapacitor module, which act as a power buffer for low-speed and light-duty e-mobility, result in over 80% increase in the number of cycles of typical electrochemical batteries. The solution also enables more efficient absorption of transient energy from on-board energy sources to increase the driving range per charge.
Our on-going R&D of wide bandgap (WBG) semiconductor power devices promises to enable fast charging and wireless capabilities, paving the way for vehicle-to-vehicle and vehicle-to-infrastructure energy sharing.

The electrification of last-mile transportation needs to solve two technical hurdles – short battery life, high battery cost, and rapid battery degradation with intermittent energy charging.
Hessner resolves this with a patent-pending specialty hybrid energy storage system (HESS) that uses supercapacitors with intelligent power management system (PMS) as power-buffer to capture transient energy sources and deliver power boost more efficiently at dynamic peak power cycles. The Hessner prototype acts as a surge protector for the on-board battery during peak power discharge and enables fast charging of on-board energy storage systems (ESSs) without degrading the battery's capacity and performance.
