Revolutionary Solid-state Power Controller
Engineered for the future of electric mobility, HIITIO’s Solid-state Power Controller (SSPC) replaces traditional mechanical components such as contactors and fuses with advanced power semiconductors — delivering unmatched safety, efficiency, and intelligence.
Designed for EV and eVTOL applications, the SSPC represents a new generation of smart power distribution, also known in EVs as the intelligent Battery Disconnect Unit (iBDU).
Ultra-Fast Fault Protection
When a fault current or collision occurs, the SSPC isolates the fault and cuts off the current within microseconds — far faster than traditional relays, which typically respond in milliseconds and may even experience contact sticking, preventing safe disconnection.
Simplified, Plug-and-Play Design
By eliminating the complex wiring, copper busbars, and component assemblies of traditional BDUs, the SSPC’s plug-and-play architecture dramatically reduces system complexity and lowers assembly costs.
Extended Lifespan and Superior Reliability
Traditional contactors suffer from contact wear after long-term switching, with a typical lifespan of only 100,000–200,000 cycles. The SSPC’s semiconductor-based switching greatly minimizes mechanical wear from electrical and thermal stress, achieving a lifespan of up to 1,000,000 cycles for enhanced reliability.
