Abstract: An electronic control for engine block heater elements for heating an engine to an engine ready temperature includes a power input, a power output, and a controller. The controller includes a clock for keeping a time and a temperature sensor for sensing a temperature. The controller is configured for controlling the power from the power input to the power output in at least two modes of operation for heating the engine to the engine ready temperature. The second mode of timed ready is where the power from the power input to the power output is connected at a pre-calculated time interval for the purpose of making ready the subject vehicle for starting at the desired start time as set by the user. The third mode of maintain ready is where the power from the electrical outlet to the engine block heater element is regulated to maintain the engine ready temperature.

Abstract: A power control system supplies electric power to a plurality of power consumption devices which are provided to an electric vehicle. This system includes: a high voltage battery which is an electric power supply source; a plurality of device controllers which are provided to the respective power consumption devices and which control operations of the respective power consumption devices; and an overall controller which overall controls the plurality of device controllers. At least one of the device controllers performs an electric power restriction that restricts a consumed electric power in a corresponding power consumption device so as to allow the consumed electric power in the corresponding power consumption device to fall within an electric power allocated by the overall controller while simultaneously maintaining an operation of the corresponding power consumption device stably.

Abstract: A battery charge system includes an on board charge module, a high voltage battery pack unit and a controller. The on board charge module includes a power conversion device, a switching unit coupled to the power conversion device, and an electrothermal element coupled to the switching unit. The power conversion device includes an AC/DC converter and a bidirectional DC/DC converter. The AC/DC converter has an input terminal coupled to an AC terminal, and an output terminal coupled to an input terminal of the bidirectional DC/DC converter. The high voltage battery pack unit includes a first switching element and a high voltage battery pack. The high voltage battery pack is coupled through the first switching element to an output terminal of the bidirectional DC/DC converter. The controller is coupled to the power conversion device and the switching unit, and is configured to control the power conversion device and the switching unit.

Abstract: An energy storage system for supporting dual electrical functions of a vehicle includes an energy storage unit having a plurality of energy storage modules connected in series, a plurality of sensing units for sensing state of charges of the plurality of energy storage modules, and a pair of primary voltage terminals. The series connected plurality of energy storage modules is connectable across the pair of primary voltage terminals during a key-on state of the vehicle to supply energy storage power at a first voltage level to support primary electrical functions of the vehicle. The energy storage system is further configured to select a subset of the plurality of energy storage modules during a key-off state of the vehicle to connect across a pair of secondary voltage terminals using a switch network to supply energy storage power at a second voltage level.
