Electric vehicle charging switch solution

Electric vehicle plug

Electric vehicles have become a part of our lives today and charging a car has become a simple task – you just need to plug/unplug.

Similar to mobile phone charging cables, car charging cables usually have two plugs, one plugged into the socket on the car and the other plugged into the charging pile socket. However, due to factors such as current, charging speed or different countries, the charging interface of the car will be different.

Fortunately, standards already exist that govern charging ports, and even if things change in the future, perhaps the path will be toward a universal standard for all cars.

Plug switch

Used to detect the locked and unlocked state of charging plugs when connected to the commercial power grid (indoors and outdoors), these plugs have 3 standards:

• IEC 62196-2 (CCS Type 2)

• GB/T 20234-2

• SAE J1772 (CCS Type 1)

Charging Station

Applied to charging port or control panel

HVIL or High Voltage Interlock Loop

It is a safety feature in hybrid and electric vehicles that protects people during vehicle assembly, repair, maintenance and operation.

The HVIL acts as a circuit breaker, using a continuous low-voltage loop to monitor all high-voltage connectors and components in an electric vehicle (EV). If the low-voltage HVIL signal is interrupted for any reason, it indicates a problem with the high-voltage system that needs to be addressed.

The heart of the HVIL is concerned with the power connector, but the HVIL control unit may include a switch that provides access to the high voltage components.
