Maxwell Technologies BMOD0018-390V Ultracapacitors
390 Volt Heavy Duty Transportation Module Overview
The new BMOD0018-P390 (HTM390) module is based on 2.7-volt BOOSTCAP® power cells and incorporates proprietary balancing, monitoring and thermal management capabilities to ensure industry-leading charge/discharge performance, high reliability and long operational life.
The HTM390 meets or exceeds transportation industry requirements for watt-hours of energy storage and watts of power delivery per kilogram, and is designed to perform reliably through one million or more deep charge/discharge cycles, which equates to more than 15 years of operational life.
HTM390 Features:
- 390V operating voltage
- Monitoring provisions for temperature and voltage
- Over 1 million duty cycles
- sealed from exposure to the elements by being compliant with the IP 65 requirements as detailed in the IEC standards
- Proprietary material science and packaging technology
Applications:
- Regenerative Braking
- Torque Assist Systems
- Engine Starting
