CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY
The present application claims priority from the Indian provisional patent application, having application number 202241029623, filed on 23rd May 2022, incorporated herein by a reference.
TECHNICAL FIELD
The present disclosure relates to electric vehicle charging connectors and more particularly, the present subject matter relates to a system and method of improving the current carrying capacity of electric vehicle charging connector contact(s).
BACKGROUND
Nowadays, with increasing consumption of fuel, the cost of mobilization is increasing every day. Therefore, electric mobility has become an essential part of modern mobility solutions. Further, with increasing global warming and air-pollution, the relevance of electric mobility is increasing day-by-day. However, the main problem of electric mobility is having sufficient and efficient charging infrastructure. Main aspect of charging infrastructure is efficient transfer of electric energy. Therefore, efficiency of a connector assembly which is configured to transfer electric energy through a conductor which comprises transmitter (male) and receiver (female). Generally, connectors mainly comprise power contact(s), fluid contact(s), signal contact(s) and earth contact(s). Generally, power contact(s) and fluid contact(s) are assembled with each other by fluid contact(s) being spiralled around the power contact(s) or the heatsink or heat absorbing element connected in between which transfers the heat from the power contact(s) to the fluid contact(s). However, the capacity of such connectors is very much limited especially for operations where power transfer more than 500A is required because for larger energy transfer at faster speed one requires either increasing size of power contact(s) or increasing number of power contact(s). However, such arrangement becomes bulky and requires more fluid to keep temperatures under control.
Further, going with the need of fast charging infrastructure, a high current needs to be passed via the charging connector to enable fast charging of an electric vehicle. The charging connector used for passing high current, needs to have adequate size to overcome the thermal generated due to i2r losses (Power loss due to Current flowing through Resistance). If the sizing of the connection is not designed properly, the system will heat up due to internal resistance of the materials and eventually fail in life or performance. The failure mode includes the metallic plating going off or fretting corrosion. Thus, one of the major limitations to pass high current in a vehicle charging connector is the size required to handle the current and making it not feasible to make above 500 A, eventually leading to limiting the charging time of the battery.
Thus, there is a long-felt need for a method of improving the current carrying capacity of electric vehicle charging connector contact(s) which can improve the speed as well as efficiency of charging the vehicle and also is less bulky and simple in functioning and handling.
