Toshiba recently announced the launch of a vehicle optical relay "TLX9165T", which features a 10-pin SO16L-T package and supports high-voltage vehicle batteries with an output withstand voltage of 1800V (minimum value). This product is now available for bulk shipment.

Shorter charging times and longer driving ranges are crucial for the development and popularization of electric vehicles, and both require more efficient operation of the battery system. The Battery Management System (BMS) achieves efficient operation of the system by monitoring the charging status of the battery, and at the same time, it monitors the insulation condition between the battery and the vehicle body to ensure the safe use of high-voltage batteries. The BMS that needs to handle high voltages is adopting electrical isolation optical relays.

The energy storage system (ESS) also adopts a configuration similar to that of the BMS, ensuring the efficient operation of renewable energy. Since energy storage systems also handle high voltages like electric vehicles, they are also one of the important application markets for electrical isolation optical relays.

Although 400V battery systems are currently the mainstream for electric vehicles, as the demand for longer driving ranges and faster charging speeds continues to grow, electric vehicles will accelerate their transition to 800V battery systems. The optical relays used in these battery systems must have a withstand voltage of approximately twice the system voltage. Therefore, for an 800V battery system, the withstand voltage value needs to be above 1600V. Toshiba has launched a new optical relay, which adopts its latest high-voltage MOSFET and has an output withstand voltage of 1800V (minimum value), making it suitable for 800V battery systems.

The 10-pin SO16L-T package of the opto-relay is made of a resin having a relative tracking index (CTI) of 600 or more, which is a class I material in the IEC 60664 1 international standard, and the pin arrangement thereof ensures a creepage distance of 7.5 mm or more on the side of the optical receiver.These specifications comply with IEC 60664 -1 and are available up to 1500 V.

The pin pitch and pin configuration are the same as those of the SO16L-T package, allowing for a universal PCB pattern design.

In the future, Toshiba will continue to expand its optical relay products suitable for battery systems in automotive applications and energy storage systems of industrial equipment, contributing to the safe operation of the equipment.
