Abstract:
Es ist bekannt, eine elektrische Batterie eines Hybridfahrzeugs bei einem Kaltstart, bei dem die Batterie zunächst nicht für eine Leistungsentnahme bereitsteht, durch wechselndes Entladen und Beladen zu heizen. Bevorzugt wird das Heizen gleichzeitig dazu genutzt, den Beladungszustand der Batterie zu ändern. Dann kann mit dem Heizen unmittelbar mit dem Kaltstart bereits begonnen werden, ohne dass die elektrische Batterie zuvor in einen bestimmten Beladungszustand gebracht werden muss.
Abstract:
A hybrid system including a hybrid control module for operating the hybrid system to as to have its energy storage device meet a predetermined service life metric is disclosed. The hybrid control module stores experimental information indicative of the impact of certain usage parameters on the service life of the energy storage device, monitors the actual usage parameters observed during operation of the hybrid system, and dynamically determines a maximum operating temperature for the energy storage device in order to increase or decrease its utilization by the hybrid system.
Abstract:
Die Erfindung betrifft ein Verfahren zum Betreiben eines Kraftwagens mit einem Hybridantrieb (10), bei welchem zumindest ein Betriebsmedium des Kraftwagens mittels einer dielektrischen Heizvorrichtung (36, 38) auf eine vorgegebene Solltemperatur aufgeheizt wird. Hierdurch können von dem Betriebsmedium durchströmte Komponenten unmittelbar nach einem Kaltstart des Kraftwagens besonders schnell auf ihre optimale Betriebstemperatur gebracht werden, so dass ein besonders energiesparender Betrieb des Kraftwagens möglich wird.
Abstract:
The invention provides a power storage system of a hybrid vehicle in which a battery can be charged with electric power supplied from an external power supply. The power storage system includes an engine heater and a battery heater, a DC/DC converter that converts a voltage of input power and outputs the power to the engine heater and the battery heater, respectively, a charger connected to the external power supply and operable to outputs power supplied from the external power battery to the battery and the DC/DC converter, and a controller that performs external charge control for charging the battery with power supplied from the external power supply, and temperature regulation control for raising the temperatures of the engine and the battery, by supplying power from the external power supply to the engine heater and the battery heater via the DC/DC converter, until the external charge control ends.
Abstract:
A thermal management system for a vehicle includes a traction motor and a battery pack. The thermal management system comprises a battery circuit for cooling a battery circuit thermal load including the battery pack, a battery circuit temperature sensor positioned to sense a temperature relating to a temperature of the battery circuit thermal load, and a controller. The controller is configured to control the battery circuit to maintain the temperature sensed by the battery circuit temperature sensor below a first battery circuit temperature limit when the controller detects that the vehicle is not connected to an external electrical source, and to maintain the temperature sensed by the battery circuit temperature sensor below a second battery circuit temperature limit that is lower than the first battery circuit temperature limit when the controller detects that the vehicle is connected to the external electrical source.
Abstract:
The invention relates to a method for operating a motor vehicle with a hybrid drive (10), in which at least one operating medium of the motor vehicle is heated to a predetermined desired temperature by means of a dielectric heating device (36, 38). By this means, immediately following a cold start of the motor vehicle, components through which the operating medium flows can be brought particularly rapidly to the optimum operating temperature thereof such that a particularly energy-saving operation of the motor vehicle is possible.
