Electric vehicles require reliable high-voltage isolation to ensure passenger safety and system stability. Standex reed relays provide high isolation, low power consumption, and long life for e-car isolation measurement.
“When properly designed in, the reed relays’ features will stand up to the high requirements of modern electric devices very well.”
Internal isolation measurement systems require a reliable switching component that can handle high-voltage isolation. That’s where Reed relays come in.
Hybrid and electric drivetrains in cars, lorries, and two-wheelers are introducing new, previously unknown challenges in the transport industry. The 12V or 24V on-board network is now complemented by a 400V or higher battery and power system, which introduces a completely new set of requirements for car OEMs and system module providers.
Operating with such high voltage and current in a harsh automotive environment drives the need for robust and long-term stable solutions for isolating high voltage levels from other electronic functions, but most importantly from the passengers.
This isolation need is present in all functions of the hybrid and electric vehicle, such as the high voltage battery, the DC-DC converter, the inverter for driving the electric motor, and also the charger module connected to the 230V/380V power grid. Therefore, electric vehicles contain an internal measurement system.
This system checks all electrical parameters such as isolation and dielectric strength (isolation resistance between active and electronic components and the frame). To switch or cut such an isolation measurement system to the power system, high isolation is required.
Reed relays from Standex Detect are more than suitable to fulfil such requirements. Despite its small size, the relay has an isolation resistance in the T Ohm range. Another advantage is low power consumption. Reed relays only need energy during the switching process, which has a positive influence on the overall efficiency of the E-Car. Reed relays are well sealed, making them insensitive to dirty and dusty environments.
