Reed Sensors in Electric Car Chargers
Electrical cars are designed to have a range of 250-300 kilometers on a full charge. To ensure that the charging time is minimal, 16-32 Amps may be required for charging. For high current charging, it is very important that the mating of the contacts inside the connectors not only conform to requirements but also ensure that they provide a complete lock-in so charging problems don’t occur. To aid in good mating of connectors, reed sensors are built into the charging sockets of electric cars and a magnet is provided at the end of the charging cable. This ensures that a correct locking signal is passed on to the charging circuit to trigger start of the charging. These reed sensor(s) are constantly monitored during the charging to provide constant feed back to the charging circuit.
Applications are classified as Position Sensing, Pulse Counting, Electromagnetic or Relay, Temperature Sensing or Magnet Biasing types. This application is classified as follows and the link gives more information on best practices to help select the most suitable AT band and matching magnet.
The Reed Switches and Sensors used in such applications need to be robust, durable and efficient in meeting a high life expectancy. Our engineers work hard in life testing our products under various conditions, and our intention is to ensure end product durability and life. Although we wouldn’t want to restrict any of our products for use in only certain applications, the recommended products for use in this application are listed below.
