Ioncentric

Its eiscube device measures battery capacity and health in the field using high-precision Coulomb counting with self-calibration. It runs alongside existing battery management systems and connects over CAN, Modbus, RS485 or Ethernet. The ioneis cloud platform analyzes data from that hardware or from a customer's BMS to forecast remaining useful life and capacity fade. The company also offers a digital product passport for each battery, and targets energy storage, industrial and mobility systems.

Ioncentric GmbH is registered in Heilbronn, Germany, and is part of the Future GreenTech Incubator in Goslar. In March 2026 its eiscube and ioneis cloud system won the Embedded Award in the hardware category at embedded world in Nuremberg.
