The increasing electrification of transportation has led to a growing interest in the 48 V power architecture among manufacturers of two- and three-wheeled vehicles. With electric scooters, motorcycles, tuk-tuks, and recreational vehicles increasingly relying on electricity as their fuel source, the need for a reliable and high voltage power supply of 48 or 96 V is crucial. Gruner AG has developed new 48 V and 96 V relays to meet these requirements. These relays can sustain high currents of up to 150 A at 48 V DC or 120 A at 96 V DC, while safely disconnecting short circuits of up to 4 kA. Additionally, they offer monitoring features such as contact and temperature monitoring. With the rise of electric two-wheeled vehicles, Gruner’s new relays contribute to making the transition to electric propulsion attractive and secure.

Gruner relays ensure high short-circuit resistance, protecting vehicles and people
The relays developed by Gruner are designed with a high short-circuit resistance, ensuring the safety of both individuals and vehicles by protecting them from damages caused by high currents or battery overheating. These relays are capable of reliably disconnecting short circuits of up to 4 kA. Additionally, their shock resistance allows them to withstand impacts of up to 150 g, making them ideal for use in two- and three-wheel vehicles that are frequently subjected to vibrations.
Integrated NTC temperature sensor ensures safe operation of relays
The relays from Gruner are equipped with an integrated NTC temperature sensor, which serves as a temperature monitoring module and displays the functional status of the relay in the battery management system. Additionally, the contact position can be monitored to determine whether the relay is open or closed. The diagnostic signal is extracted via the connector and transmitted to the battery management system, enabling the detection of the respective switching position for ensuring a safe ride.
Gruner AG to Launch Enhanced Relay Series for Electric Two- and Three-Wheelers
Gruner’s optimized relay series, available in both monostable and bistable versions, is set to revolutionize the transition to electric propulsion in the two- and three-wheeler segments. With a planned production start in early 2025, these relays are designed to enhance the attractiveness and safety of electric two-wheelers. Leveraging their expertise in manufacturing high-quality and reliable relays, Gruner aims to support the future of electromobility where electric vehicles powered by electricity are the norm.
