96 VDC Relay Designed for BMS in Electric Motorcycles and Compact Mobility

Contents
What is the 96 VDC Relay G9EL
(Under Development)?
The G9EL is a compact relay rated at 96 VDC / 100 A that contributes to higher power, smaller size, and lighter weight in small mobility.
This product is specifically designed for the BMS (Battery Management System) market, which is growing with the advancement of electric mobility, and the key strengths lie in its high capacity combined with a compact and lightweight design.
*As this product is currently under development, specifications are subject to change without prior notice.


Because automotive relays are used as-is, they are large and heavy

[Comparison with our conventional product]
*According to OMRON's research in September 2025
Capable of meeting the high-voltage requirements of equipment
This product can meet the high-voltage requirements of equipment, which were difficult to address with conventional specifications. OMRON has achieved the difficult balance between high voltage and miniaturization by efficiently suppressing arcing through its unique combination of simulations of the airflow generated by the arc and the magnetic circuit required for arc control. (Patented)
Example of airflow analysis results
Visualizes the pressure difference caused by arcing.
By predicting and controlling the airflow, arcs that occur are efficiently extinguished.
Magnetic field analysis
The magnetic field design required for arc control can be realized through analysis.
Contributing to the reduction of the review period and the improvement of design quality
The 96 VDC specifications ideal for BMS
The 96 VDC relay specifications are ideal for motorcycles and small mobility vehicles, helping to reduce selection time.
This product offers specifications ideal for BMS energization and interruption control applications.
This product is designed for continuous energization at a maximum of 100 A and emergency current interruption (10 times or less).

Frequently Asked Questions
- Q1. Can I request product samples?
- ― A. We can provide you with evaluation samples. Please be advised that our staff may contact you to inquire about your company's challenges and usage conditions. Our standard inventory is limited, so delivery may take time depending on your requested timing and quantity. We appreciate your understanding in advance.
- Q2. Has this product already been released?
- ― A. This is a pre-release product, but if you contact us, our staff will reach out to you regarding sample provision and other matters.
- Q3. What are OMRON's unique strengths?
- ― A. We have achieved high voltage and compact size through innovative arc control using OMRON's patented technology.
- Q4. Has this product been adopted?
- ― A. As this is a pre-release product, we currently have no sales records. However, several companies, including motorcycle manufacturers, are considering its adoption.
- Q5. Has this product obtained UL, TUV, or other certification standards?
- ― A. This product has not obtained standard certifications such as UL and TÜV. It is a relay that has achieved a compact size by designing it with insulation distances shorter than those specified by standards.
This product is recommended for applications where standard certification is not required, or where certification is performed on the entire unit system rather than the relay alone.
