The Mini K HV supports the connection and disconnection of the traction battery in switching assemblies for hybrid and battery electric vehicles. As a compact precharge relay, the Mini K HV takes over the charging of the filter capacitors over a precharge resistor directly before the operation of the main relay, protecting the main relay’s contacts from extreme inrush currents.
With significantly reduced dimensions of 25.5x20.7x19.3mm for the PCB version, the Mini K HV represents a major innovation compared to current precharge relay solutions. A specially optimized design of the switching contacts enables this miniature relay to switch loads of up to 20A at a system voltage of up to 450V. Even under fault conditions, it is able to reliably disconnect the precharge circuit from the traction battery. In addition to the standard version with printed circuit board terminals, it is also available as a plug-in relay with quick-connect terminals.
