Problems solved by technology

However, this limits the range of functions, since there are many combinations in which the threshold value is too low
In other words, this wastes the potential of transferring electrical power for fast charging of the energy storage

Embodiment Construction

[0026] figure 1 A motor vehicle 1 is shown, which can be, for example, a motor vehicle, in particular a passenger vehicle. Shown is a vehicle rear 2 in a motor vehicle. Motor vehicle 1 may be, for example, an electrically driven motor vehicle or a hybrid vehicle. The motor vehicle can have an energy store 3 , for example an on-board battery, in particular a high-voltage battery, for operating a propulsion electric machine (not shown). The energy store 3 can be charged via a charging station 4 outside the vehicle. For this purpose, the charging station 4 can be electrically connected to the motor vehicle 1 via a charging cable 5 . Motor vehicle 1 can have a charging device 6 for this purpose. The charging device 6 can have a charging socket or socket 7 and a charger 8 . The charger 8 may be a device type that can be installed into different vehicle models. Nevertheless, the charger 8 is designed to efficiently charge the energy store 3 in the motor vehicle 1 using the the...

Abstract

The invention relates to a method for recognising an over-temperature in a region of a charging socket (7) of a motor vehicle (1) without a temperature sensor. The object of the invention is to efficiently use the thermal operating limitations of the charging socket (7). A temperature value (T) is detected by means of a temperature sensor (11) at an installation location of the temperature sensor (11) that is different from the region. At least one configuration value (PRX, I, G) of a current operating configuration, in which the charging socket (7) is operated, is determined, and subsequently a temperature reading for the region without a temperature sensor is generated by means of a characteristic map (14) that is designed to include the temperature value (T) and the at least one configuration value (PRX, I, G) as input variables, and to assign the temperature reading to these input variables. For the protection of the charging socket (7), a protective measure for the charging socket (7) is triggered according to the temperature reading.

Description

technical field [0001] The invention relates to a method for detecting an overheating temperature in a region of a charging socket of a motor vehicle without a temperature sensor. Protective measures for the charging socket are triggered when an overheating temperature is detected. The invention also includes a charging device for a motor vehicle, by means of which the method according to the invention can be carried out, and a motor vehicle having the charging device. Background technique [0002] In a motor vehicle, an electrical energy store, such as a battery, in particular a high-voltage battery, can be provided for operating the propulsion electric machine. High voltage is here understood to mean a voltage of greater than 60 volts, in particular 100 volts. To charge the energy store, a charging cable from a charging station outside the vehicle can be connected to the charging socket or charging socket of the motor vehicle. Components of the charging socket can becom...
