Abstract
(EN)
An electrical connector and a quick-change connector for a battery pack of an electric vehicle, the electrical connector (21) comprising a pole (211) and a first accommodating cavity (212) surrounding the pole (211), and further comprising a seal detection device. The seal detection device comprises a pressure measurement unit, the pressure measurement unit being located in the first accommodating cavity (212) and being used for measuring the pressure change when the first accommodating cavity (212) is in a sealed state. The pressure measurement unit measures the change of air pressure in the cavity of the quick-change connector, so that whether the sealing of the quick-change connector is normal is determined in a timely manner, thereby issuing a warning in a timely manner and avoiding a vehicle fault.

L'invention concerne un connecteur électrique et un connecteur à changement rapide pour une batterie d'un véhicule électrique, le connecteur électrique (21) comprenant un pôle (211) et une première cavité de réception (212) entourant le pôle (211), et comprenant en outre un dispositif de détection d'étanchéité Le dispositif de détection d'étanchéité comprend une unité de mesure de pression, l'unité de mesure de pression étant située dans la première cavité de réception (212) et étant utilisée pour mesurer le changement de pression lorsque la première cavité de réception (212) est dans un état scellé. L'unité de mesure de pression mesure le changement de pression d'air dans la cavité du connecteur à changement rapide, afin de déterminer en temps opportun si l'étanchéité du connecteur à changement rapide est normale, ce qui permet d'émettre un avertissement en temps opportun et d'éviter une panne de véhicule.
