Many power and automotive relays are used in EV/PHV.
For example, control of fuel injection pump motors, control of head lamps and blinkers, windshield wipers and power windows, connection of power supply line between a hybrid vehicle external charger disconnect and its battery system. Major selection criteria is the rated current.
Power Supply System for EV/PHV
Power supply systems are the key for the expansion of EV/PHV.
Relays, mainly high-capacity power relays, are used to keep power systems safe.
Relays used in automotive electronics must be highly reliable and meet IATF16949 requirements.
Major selection criteria is the rated current. Noise level (quietness) is an important selection criteria for high-end cars.
Car Navigation/Car Audio Systems
Touch panels are used to operate automotive interfaces such as car navigation or car audio systems.
Wireless modules are used for communication with automotive interfaces.
Thermal printer mechanisms are used in taxi meters to print receipts.
The eCall system is designed to improve emergency response times following a traffic accident. The Emergency Call Unit (ECU) automatically transmits accident information to emergency response services, such as the vehicle’s location and allows emergency responders to speak with passengers. This greatly reduces the initial response time.
Signal relays (FTR-B3 or FTR-B4 series) are used inside of the ECU.
