摘要:
An Engine Start and Battery Support Module (or a vehicle is provided that utilizes a bank of Ultra Capacitors (UCs) charged with or without running the vehicle's alternator to levels that support both engine starting assistance and hotel load support. The UCs' per-cell charge can be adjured and raided during periods of low temperatures and even higher during ultralow temperatures. The adjustment, which can be dynamic and/or automatic, increases the UC energy storage capability. Further, the release of energy from the UCs is controlled by a pulse width modulation (PWM) controller based on the DC bus voltage. The UCs can be charged either from an onboard DC/DC converter, an AC hook up, or from smartly switching the banks of UCs between parallel and serial configurations.
