HIITIO today announced the release of its next-generation Solid-state Intelligent Battery Disconnect Unit (iBDU) for electric vehicles (EVs) and Solid-state Power Controller (SSPC) designed for eVTOL aircraft and advanced aviation power systems. Leveraging Silicon Carbide (SiC) JFET technology, High Voltage E-Fuse architecture, and solid-state circuit breaker and solid-state relay functionality, the new product line redefines safety, speed, and reliability in high-voltage power distribution.
As EVs continue to scale globally and eVTOL technology accelerates toward commercialization, traditional relay-based or mechanical contactor power distribution systems are reaching their limits. HIITIO’s latest solid-state solutions leverage advanced semiconductor switching, real-time monitoring, and ultra-fast protection capabilities to deliver a new standard of efficiency and safety for next-generation electric platforms.
Reinventing High-Voltage Control with Solid-State Technology
HIITIO’s new solid-state architecture eliminates the mechanical wear, switching delays, and arc-related risks seen in conventional contactor-based BDUs. Key product highlights include:
- Ultra-Fast Fault Interruption (< 10 μs)
Solid-state switching enables microsecond-level short-circuit interruption—thousands of times faster than mechanical relays—greatly reducing thermal runaway and electrical arc risks.
- Arc-Free, Silent, and Maintenance-Free Operation
With no mechanical contacts, the iBDU and SSPC avoid contact welding, erosion, or bounce, ensuring higher operational stability over the full system lifetime.
- Over 1,000,000 Switching Cycles
Semiconductor-based architecture delivers an extremely long service life, ideal for high-cycle applications such as EV battery systems and electric propulsion modules.
- Compact, Lightweight, High Power Density
The solid-state platform integrates switching, sensing, and protection functions into a single compact unit—minimizing wiring, reducing system complexity, and lowering overall weight.
- Intelligent Monitoring & Communication
Built-in temperature, voltage, and current sensing provides real-time diagnostics and health monitoring. CAN, RS485, and configurable hardware signals ensure seamless integration.
Solid-state iBDU: A New Foundation for Electric Vehicle Battery Systems
HIITIO’s new EV-focused solid-state iBDU replaces the traditional multi-component system of contactors, fuses, pre-charge relays, current sensors, and complex wiring harnesses. By consolidating these elements into a unified, semiconductor-based module, the iBDU provides:
- Instant fault isolation and microsecond-level protection
- High system reliability without mechanical degradation
- Reduced cost and design complexity for OEM battery packs
- Significant improvements in safety and lifetime performance
For EV manufacturers seeking higher reliability, simplified architecture, and enhanced safety margins, the iBDU delivers a future-ready solution aligned with global electrification trends.
SSPC for eVTOL: Aviation-Grade Reliability for Future Air Mobility
Electric vertical-takeoff-and-landing aircraft demand an extraordinary level of electrical reliability, efficiency, and weight reduction. HIITIO’s SSPC is purpose-built to meet the rigorous requirements of eVTOL and advanced aerospace systems:
- Ultra-fast and precise switching for mission-critical applications
- Silent, arc-free operation suitable for aviation environments
- Lightweight design supporting aircraft efficiency and longer range
- Exceptional thermal stability and immunity to vibration, EMI, and harsh conditions
As the aviation industry advances toward Urban Air Mobility (UAM) and fully electric propulsion, the SSPC delivers the reliability and intelligence essential for safe and scalable airborne operations.
Driving Global Electrification with Smarter, Safer Power Control
HIITIO’s solid-state technology helps system integrators and OEMs achieve:
- Higher safety through fast fault responses and continuous monitoring
- Lower total system cost by reducing mechanical components
- Improved functional safety and system intelligence
- Greater design freedom and simplified architecture
From road vehicles to aircraft, high-voltage platforms are rapidly transitioning to semiconductor-based power control. HIITIO’s new iBDU and SSPC accelerate this transformation, offering robust solutions tailored to the future of electric mobility and aviation.
A Future Built on Collaboration and Innovation
HIITIO invites EV manufacturers, eVTOL developers, battery system integrators, and energy-storage partners worldwide to collaborate in developing next-generation electric systems powered by solid-state technology. With the launch of the solid-state iBDU and SSPC, HIITIO reaffirms its mission: enabling safer, smarter, and more efficient electrification for ground and air mobility.
