Abstract:
A vehicle includes a temperature control system, a battery configured to power the temperature control system, and a controller. The controller is programmed to, in response to a request to precondition the battery or the cabin air, an absence of receiving a signal indicative of a desired initial battery state of charge, and an actual battery state of charge being greater than a default threshold, deliver electrical power from the battery to the temperature control system at a desired value. The controller is further programmed to, in response to the request to precondition the battery or the cabin air, receiving the signal indicative of the desired initial battery state of charge, and the actual battery state of charge being greater than the desired initial battery state of charge but less than the default threshold, deliver electrical power from the battery to the temperature control system at the desired value.
Abstract:
Methods and systems are disclosed for remotely and/or automatically controlling electronic components. The electronic components may be elements/systems of a vehicle (e.g., heating elements). In an aspect, a controller may receive a temperature value from a sensor. The controller may activate a heater based on the temperature value of the sensor. In an aspect, the heater is coupled to one or more parts of an engine.

A plug-in connector part for connection to a mating plug-in connector part includes: a housing which has a plug-in portion for plug-in connection to the mating plug-in connector part; at least one contact element arranged on the plug-in portion and for electrically contacting an associated mating contact element of the mating plug-in connector part; a thermal conductor line connected to the at least one contact element; and a cooling body arranged in the housing and thermoconductively connected to the at least one contact element via the thermal conductor line in order to dissipate heat from the at least one contact element.
Abstract:
A control unit, at the time of a heating operation, pressure-reduces refrigerant that has passed through an indoor condenser, by an expansion valve, and thereafter introduces the refrigerant into an outdoor heat exchanger to thereby perform heat exchange with outside air. Further, the control unit, at the time of a defrosting operation, introduces high-temperature and high-pressure refrigerant compressed by a compressor into the outdoor heat exchanger to thereby remove frost adhering to the outdoor heat exchanger. Furthermore, the control unit determines whether to perform the defrosting operation or not, based on the amount of electric power required for the defrosting operation.
Abstract:
An improved control arrangement is used in a high power rectifier and comprises two or more power controllers ganged together in parallel. Each power controller rectifies an AC voltage signal using zero voltage crossing switching to produce a binary switched signal and each power controller is connected to an independent connectable load. Each power controller includes a fast acting binary power switch that selectively connects the respective independent connectable load to the rectified AC voltage signal. The control arrangement selectively activates the power controllers to define a desired connected load. This high power rectifier and control arrangement is advantageously used to provide fast up down power regulation to a grid by selective storage of thermal energy and deriving power from the thermal energy storage system to add fill in power to the grid.

Abstract:
A method for managing energy to a transport climate control system from a vehicle electrical system is provided. The vehicle electrical system includes a vehicle power network and an auxiliary power network connected to a transport climate control load network via a DC regulated bus. The method includes monitoring a vehicle voltage of the vehicle power network and determining whether the vehicle power network requires holdover assistance based on the vehicle voltage. Also, the method includes the bus sending vehicle power energy generated by the vehicle power network to the transport climate control load network without assistance of the auxiliary power network when the controller determines that the vehicle power network has sufficient power capacity available, and the bus sending the vehicle power energy and auxiliary power energy stored by the auxiliary power network to the transport climate control load network when the controller determines that the vehicle power network requires holdover assistance.
