What Stercom does
Stercom Power Solutions GmbH is a German designer and manufacturer of high-voltage energy storage and charging systems for industrial, mobility, and research applications, headquartered in Weyarn, Bavaria. Its product portfolio spans onboard chargers (OBC 22kW and the bidirectional OBC V2X enabling Vehicle-to-Grid, Vehicle-to-Building, and Vehicle-to-Load), battery management systems (BMS-X for stationary, MBMS for mobile, and String Management Units), and high-performance energy storage systems including the UltraCap Power Booster (ultracapacitor-based, up to 5 MW peak, >1.2M cycles) and LTO Storage Systems (up to 15C discharge, >20,000 cycles). Underlying technologies include proprietary Dynamic Cell Balancing (DCB), String Management Unit (SMU), and Active Front End (AFE) electronics achieving power factor >0.99, with systems scalable to 1200V string voltage and ISO 9001 manufacturing in Germany.
The company sells primarily via direct enterprise sales to OEMs, fleet operators, industrial customers, and energy suppliers, supported by named account managers, web-based sales inquiry forms, and participation in industry fairs. Hardware revenue (OBC, BMS, ESS) is complemented by aftermarket services — commissioning support (€495 for the initial four hours), hourly consulting (€150/h), spare parts, firmware updates, and repair — with pricing for hardware quote-based and not publicly disclosed. End-use segments cover e-mobility (rail, marine, mining, construction, airport GSE, logistics AGVs, commercial vehicles), industrial high-power applications (launch coasters, peak shaving, UPS, energy recuperation, test facilities), and stationary battery management for grid and backup applications. Reference customers include Siemens Mobility (BMS for new battery-powered trains) and HITec at Leibniz Universität Hannover (Einstein Elevator buffer/booster storage). Stercom operates as a member company of the ZAPI GROUP, a global industrial-electrification ecosystem.
