Charged EVs | Omron debuts high-capacity DC relay for use in bidirectional EV charging applications
Jun
Omron Digital Elements Europe has introduced a brand new high-capacity DC relay to be used in family electrical energy storage programs, bidirectional EV chargers and UPS programs.
The G9K8-F general-purpose relay affords a most voltage of 800 VDC and most present of 100 A. It’s appropriate for battery functions inside the 15 to 40 kW vary and, not like standard sealed relay designs, it makes use of no hydrogen gasoline, which ends up in improved security, in line with the corporate.
The brand new relay has the identical dimensions and weight as the corporate’s commonplace 9KB collection, and affords 33% greater most switching voltage and 50% greater present dealing with functionality. This enables designers to specify fewer relays per system.
The G9KB-E additionally options bidirectional DC switching capabilities. This allows using a single general-purpose relay for use rather than two unidirectional relays. The unit, Omron mentioned, additionally harnesses arc cut-off expertise to fight contact arcing.
The brand new design on this mannequin achieves a low-rated contact resistance of 5 milliohms. This ends in much less warmth era which in flip ends in extra environment friendly efficiency, in line with Omron.
