Iontra’s core innovation is its patented Charge-Control technology, which employs signal processing and adaptive algorithms to optimize battery charging without modifying existing cells or packs. It prevents electrode plating and dendrite growth, increases battery lifespan by 2–4×, reduces charging times by up to 75%, and enables safe charging at −20 °C. Chemistry-agnostic and compatible with lithium-ion and lithium-metal batteries, it is implemented via microcontrollers integrated into existing battery management systems.
RISC-V-based Charge-Control and fuel gauge microcontroller units that integrate Iontra’s patented charging algorithms. Initial samples available mid-2025, with full production starting in 2026.
In 2024, Iontra secured $45 million in Series C funding to advance its RISC-V charge control and fuel gauge microcontroller technology, targeting sample availability mid-2025 and production in 2026. The company also received a $2.15 million ARPA-E Circular Grant from the U.S. Department of Energy to develop enhanced EV battery innovations in collaboration with Idaho National Laboratory and Freudenberg to improve state-of-charge measurements.
Iontra has raised $120.3M to date. Key investors include Volta Energy Technologies (lead in Series B and C), Riverstone, and Flag Asset Management. JPMorgan Chase served as placement agent for Series B.
