Definitions
- the invention relates to a connector part for connection to a mating connector part according to claim 1, a charging station for charging an electric vehicle, an electronic assembly and a connector system.
- the connector part or a suitable mating connector part can be worn or damaged. This can, for example, lead to increased transition resistances between the load contacts of the connector part and the mating connector part. In the case of high charging currents, such contact resistances can lead to strong heating, which in turn can cause damage or even failure of the connector part.
- connector parts can be equipped with a temperature monitor in order to interrupt the charging process in the event of impermissible heating before damage occurs.
- the connector part further comprises, for example, a current measuring device for measuring a current strength of an electrical current flowing through the load contact (e.g. a charging current) as a current flow parameter.
- a current measuring device for measuring a current strength of an electrical current flowing through the load contact (e.g. a charging current) as a current flow parameter.
- Certain temperatures can be harmless with certain currents, but indicate too high a contact resistance with other currents.
- a high but still acceptable temperature can be in the normal range at a high current strength, but show a problem at a comparatively low current strength. This makes it possible to identify problems at an early stage, e.g. before a critical temperature threshold is reached.
- the evaluation unit of the connector receives the charging current, which is usually regulated by a charging station, e.g. a charging station, and / or another current flow parameter from the charging station, for example from electronics in the charging station.
- the evaluation unit optionally includes a communication interface.
- the evaluation unit can optionally be set up to calculate a relative load contact temperature based on the temperature of the load contact and the ambient temperature, e.g. by calculating the difference between the (absolute) temperature of the load contact minus the ambient temperature. In this way, a falsification of the load contact temperature due to e.g. particularly high or low ambient temperatures can be compensated.
- FIGS. 2 and 3 are views of the connector part according to FIG. 1;
- the connector part 1 comprises a housing 15 with housing shells 152A, 152B and a plug-in section 151.
- the plug-in section 151 carries the load contacts 10A, 10B, the protective conductor contact 16 and the further contacts 17.
- the plug-in section 151 is held between the housing shells 152A, 152B.
- the load contact 10A, 10B can heat up as a result.
- a contact resistance is, for example, the result of a worn contact contour of one or both load contacts 10A, 10B, contamination or corrosion.
- the plug connector part 1 each includes a temperature sensor 1 1A, 11 B for detecting the temperature of one of the two load contacts 10A, 10B.
- each of the temperature sensors 11A, 11B is arranged adjacent to (in the present case in contact with) one of the two load contacts 10A, 10B.
- the evaluation unit 12 is set up to determine relative temperatures of the load contacts 11 A, 11 B from the sensor values of the temperature sensors 11 A, 1 1 B of the load contacts 10A, 10B and from sensor values of the temperature sensor 1 1C, e.g. by forming a difference. An influence of the ambient temperature on the measured temperatures of the load contacts 10A, 10B can thus be corrected.
- the load contacts 10A, 10B are each connected to a line 20A, 20B (specifically, a direct current line) of the cable 2.
- the magnetic field sensors 140A, 140B of the load contacts 10A, 10B are each arranged on the side of the corresponding load contact 10A, 10B that faces away from the other load contact 10A, 10B. This is made possible in a particularly simple manner by receiving the load contacts 10A, 10B in the recesses 130 of the circuit board 13.
- the evaluation unit 12 records the duration of the current flow, for example, by determining how long a current intensity exceeding a predetermined threshold value, e.g. one other than zero (without interruption or with interruptions below a predetermined duration) is recorded by means of the current measuring device 14.
- a predetermined threshold value e.g. one other than zero (without interruption or with interruptions below a predetermined duration) is recorded by means of the current measuring device 14.
- the evaluation unit 12 By detecting the relative temperatures of the load contacts 10A, 10B and at least one current flow parameter, the evaluation unit 12 allows particularly precise statements to be made about the state of the connector part 1. For example, the evaluation unit 12 can recognize that with a comparatively low charging current, a comparatively high one after a short time relative temperature of one or both load contacts 10A, 10B occurs. The evaluation unit 12 can then, for example, recognize that the transition resistance is obviously too high, even before the temperature rises further. A further deterioration in the state of the connector part 1 and possibly also of the mating connector part 4 can thus be prevented in good time.
- the evaluation unit 12 is designed to output control signals, e.g. to the charging station 3, e.g. to lower or switch off the charging current in the event that the connector part 1 is in an insufficient state for a specific charging current.
- control signals e.g. to the charging station 3, e.g. to lower or switch off the charging current in the event that the connector part 1 is in an insufficient state for a specific charging current.
- the evaluation unit 12 can break off normative communication with the charging station 3 when it detects that the temperature is too high, in order to cause the charging station 3 to shut down as quickly as possible.
- the evaluation unit 12 comprises a processor 120 and a memory 121.
- the evaluation unit 12 is a microcontroller with a data memory.
- comparison values and / or threshold values are stored in the memory 121, which processor 120 can read out in order to compare them with one or more measured values.
- the evaluation unit 12 is designed to calculate a performance parameter from the measured variables of time (duration of the current flow), current strength and temperature (relative temperature of the load contacts 10A, 10B).
- the performance parameter is, for example, indicative of a performance and / or a state of connector part 1.
- the performance parameter describes the heating behavior during a charging process.
- the performance parameter can be, for example, the relative temperature increase per unit of time of the charging process.
- the performance parameter also takes into account a time interval to a previous charging process.
- the evaluation unit 12 can be designed to determine the duration between the start of the current charging process and the end of the previous charging process (and to include it in the determination of the performance parameter). In this way, any warming that has not yet completely subsided from the previous charging process can be taken into account. For example, the first charging process after a cold night shows a different temperature profile, such as the fifth.
- the evaluation unit 12 compares the determined performance parameter with default values in the memory 121. If the parameter deteriorates, the evaluation unit 12 calculates a corrective measure (for example a reduction in the current intensity by an amount corresponding to the performance parameter or switch-off) and communicates this to the charging station 3.
- a corrective measure for example a reduction in the current intensity by an amount corresponding to the performance parameter or switch-off
- the default values stored in the memory 121 correspond, for example, to the performance parameters of the plug connector part 1 in the new state or ideal state.
- a parameter profile can also be determined by the evaluation unit 12 and can be compared with a comparison profile stored in the memory 121.
- the performance parameter (by the evaluation unit 12 or the charging station 3) is forwarded, e.g. telemetrically, so that a central monitoring of many charging devices is possible in this regard.
- the temperature sensors 11A-1 1C, the evaluation unit 12, the circuit board 13 and the current measuring device 14 form an electronic assembly in the present case.
- the connector part 1 is thus a charging connector part that automatically monitors its performance (in terms of current carrying capacity). For this purpose, the charging current and duration are measured, as well as the relative temperature increase of the load contacts 10A, 10B to the environment. The ratio of two of the variables (e.g. charging current and relative temperature increase) is converted internally into the performance parameter. This is compared with the type's own values when new. In the event of deviations above a specified threshold value, the electronics in the charging plug calculate which measures (e.g. current reduction or shutdown) are to be taken by the charging device and trigger them.
- the evaluation unit 12 determines, for example, the following measured variables: the charging current, the charging time, the temperature of the load contacts, each separately for both current paths, and the ambient temperature.
- the above description in connection with the connector part 1 is merely exemplary and the connector part 1 could in particular also be designed in the form of the corresponding mating connector part 4, that is to say mounted or mountable on the vehicle 5 instead of a handle.
- a sensor system in which the evaluation unit 12 and the current measuring device 14 are arranged at the charging station 3 and the evaluation unit 12 receives the sensor values from the temperature sensors 11A-11C, for example wirelessly or via the cable 2.
