The present patent application relates to a high-voltage motor vehicle electrical system comprising an electrical heating device and at least on further consumer during switching on of which, undesired electromagnetic oscillations may occur in the electrical system. According to the invention, these are suppressed by initially switching on the heating device, before the further consumer is switched on. Switching on the heating device changes the complete impedance of the electrical system such that a resonant enhancement of the interference oscillations is prevented. Preferably, the heating device is switched on only as shortly as possible (only during the switching on process of the further consumer) in order to minimize an undesired heating.

A vehicle is equipped with an electric storage device, a drive motor, an auxiliary that can be driven by a regenerative electric power, and a control unit. The control unit performs a non-chargeable control for causing the auxiliary to consume the regenerative electric power when the electric storage device is in a non-chargeable state, and performs a specific maneuver control for causing the auxiliary to consume the regenerative electric power even when the electric storage device is in a chargeable state in the case where an operational maneuver for making a change to an operation mode in which a larger amount of the regenerative electric power is generated is performed with the regenerative electric power generated.

The system can include an on-board thermal management subsystem. The system 100 can optionally include an off-board (extravehicular) infrastructure subsystem. The on-board thermal management subsystem can include: a battery pack, one or more fluid loops, and an air manifold. The system 100 can additionally or alternatively include any other suitable components.

This patent application is directed to thermal management systems of vehicles with an electric powertrain. More specifically, the battery system and one or more powertrain components and/or cabin climate control components of a vehicle share the same thermal circuit as the battery module through which heat can be exchanged between the battery module and one or more powertrain or climate control components as needed.

An apparatus structured to control an electric vehicle accessory of an electric vehicle during a charge event includes a controller communicatively coupled to a battery and an electric vehicle accessory. The controller is structured to determine that the battery of an electric vehicle is undergoing a charge event, and based on determining that the battery of the electric vehicle is undergoing the charge event, place the electric vehicle accessory in an on-state during the charge event, and cause the electric vehicle accessory to recharge by absorbing energy from the charging station during the charge event.

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.

A method of providing coolant to an electric battery for powering a drive train of an electric vehicle is provided. The method includes providing coolant from a coolant source off-board the electric vehicle at a first rate to cool the electric battery during recharging of the electric battery; and circulating coolant through a coolant loop on-board the electric vehicle at a second rate less than the first rate to cool the electric battery after the recharging of the electric battery.
