TDK Corporation has launched the HVC50, a high-voltage dc contactor engineered for the safe and reliable connection or disconnection of lithium-ion batteries in electric vehicle (EV) traction systems, megawatt-charging systems (MCS), and energy storage systems (ESS).
Supporting voltages up to 1500 V, the HVC50 enables robust power switching in high-current applications critical to the electrification of transportation and infrastructure.
By enabling fast and efficient disconnection of up to 1500 V dc and 1000 A in under 30 ms, the HVC50 meets the demanding performance and safety needs of commercial EVs and industrial platforms. It also supports continuous operation up to 750 A, with a compact footprint (97.8 x 140 x 94.2 mm) and a weight of just 1.7 kg for streamlined integration into vehicle or system architectures.
Designed with a ceramic arc chamber and gas-filled housing, the contactor ensures safe interruption even under extreme load conditions.
A mirror contact, compliant with IEC 60947-4-1, provides accurate switching feedback for enhanced operational safety. Its bidirectional terminals support current flow in either direction, ideal for regenerative braking or bidirectional charging in EV applications. The dual-coil design (12 or 24 V operation) ensures energy-efficient control, reducing steady-state power to just 6 W after actuation.
Certified to CE, UKCA, and UL standards, the HVC50 is suitable for deployment in global markets and supports industry efforts to advance zero-emission transportation and grid-scale storage. By addressing the reliability and safety needs of high-capacity dc applications, TDK’s HVC50 plays a key role in scaling next-generation EV systems and fast-charging infrastructure.
