Passenger car high-voltage connectors need to be guaranteed for at least 15 years (≥8000 h operating life + 30000 h charging life) or at least 300,000 kilometers, taking into account other specific requirements of passenger cars.
High-voltage connectors for commercial vehicles need to be guaranteed for at least 15 years and not less than 1 million kilometers, taking into account the operating conditions specified by the customer.
The design of the high-voltage connector must ensure that it can be guaranteed for the entire life cycle of the vehicle under the condition of normal use without any maintenance.
In addition, high-voltage connectors need to meet the operational reliability under expected operating conditions (heat, cold, humidity, vibration, contact with media, current load, voltage load, etc.), and be designed in the corresponding space.
Generally, the maximum rated voltage of high-voltage connectors is 850V DC (the rated voltage must be guaranteed above 4000 meters above sea level), and it is guaranteed to meet the working temperature requirements of -40°C to 140°C.
In addition, the selection of raw materials for all components of high-voltage connectors must meet the relevant requirements of the scrapping standards of the automotive industry.
