Portable Ultracapacitor-Based Power Source for Emergency Starting of Internal Combustion Engines

Research output: Contribution to journalArticlepeer-review

Abstract

An original ultracapacitor (UC) based compact electric power source is introduced in the paper. The device employs the synergy between rich energy content of vehicle lead-acid batteries and power capabilities of UCs to allow emergency starting of internal combustion engine in case of a weak battery. The UC-based power source is capable of charging at low rate from the battery and then providing current burst required for proper engine starting. A prototype is designed employing original power circuitry, and a dedicated algorithm for optimal UC charging is developed. The device is successfully used for diesel engine starting, as shown by experimental results.
