Need help or have a question? The Proximity pin, Stqndard also known as plug presentas shown in the SAE J example pinout, describes the switch, S3, as being mechanically linked to the connector latch release actuator. DC is much faster — theoretically limitless, but it requires an external charging station. Archived from the original on The dual capability is because AC and DC each have their strengths and weaknesses.

If the plug is in the charging port of the vehicle and charging, and it is removed, the control pilot and proximity detection pin will break first causing the power relay in the charging station to open, cutting all current srandard to the J plug. However many low power adapter cables do not offer that locking actuator state detection on the PP pin.

Polestar crumples its carbon-fiber car body in first ever crash tests. Archived from the original PDF on The J standard includes several levels of shock protection, ensuring the safety of charging even in wet conditions. SAE has selected the J combo plug as the standard, which uses paired standar to allow for both AC and DC charging using the same plug. In the US, the definition of the ampacity ampere capacity, or current capacity is split for continuous and short term operation. The J has two charging plugs incorporated into a single design and is said to reduce charging times from as long as eight hours to as little as 20 minutes.
