Abstract
One embodiment includes an engine block heating system. The engine block heating system includes a battery bank. The battery bank is configured to supply at least 2.25 KWatt-hours of energy before needing to be recharged. The battery bank is configured to be mounted in a vehicle comprising an engine block heater. The system further includes interface configured to connect to electrical connections of the engine block heater. The interface comprises an inverter is configured to supply at least 1500 Watts of power to the engine block heater. The engine block heating system is configured to selectively supply power from the battery bank to the engine block heater. The system further includes control circuitry coupled to the interface. The control circuitry stores a user-defined schedule to selectively control when the interface electrically connects the battery bank to the engine block heater.
