System and method for controlling ultra-capacitor charging and discharging in vehicles with auto-start / stop systems

摘要

A system includes an ultracapacitor and battery system including a battery, an ultracapacitor, a DC-DC converter, a first temperature sensor to detect a battery temperature, a second temperature sensor to detect an ultracapacitor temperature, and a third temperature sensor Detecting DC-DC converter temperature includes. An auto-stop / start module is configured to selectively stop and restart an engine of a vehicle based on operating parameters while an ignition is on. A temperature sensing module communicates with the autostop / start module and is configured to determine differences between temperatures sensed by the first sensor, the second sensor, and the third sensor, and selectively disable the autostop / start module based on the differences ,
