Abstract
A system for use with a block heater connected to an engine for pre-start heating of the engine. The system includes a power source, a relay assembly coupled to the power source, a temperature sensor, and a controller. The relay assembly, when closed, electrically connects the power source to the block heater, to thereby energize the block heater to heat the engine. The temperature sensor senses an ambient temperature indicative of a temperature of the engine. The controller is programmed to selectively activate the relay assembly to energize the block heater such that the engine coupled to the block heater is heated from the sensed ambient temperature to a target temperature at approximately a target time.
