Implementation of Software and Hardware Solutions for Battery-Less Systems 2013-32-9094

The modern market of small engines requires low-cost solutions compatible with anti-pollution regulations. On applications without electric starter it is possible to remove the battery, but hardware and software aspects must be investigated and special solutions implemented. The main problems occur during engine fire-up (engine start), because using kick-start, only a little bit more than one engine cycle is possible for a single kick. The second aspect is that no energy is available before the crank shaft is moving, and the generator is able to supply energy to the electrical systems. Our target is to implement solutions able to start-up the ECU very quickly, ensure low consumption, and be ready to recognize engine position in the shortest possible time.
