What Maxwell does
Maxwell (Shijiazhuang Maxwell Technology Co., Ltd) is a privately held Chinese power electronics manufacturer founded in 2007 and headquartered in Shijiazhuang, Hebei Province. The company designs and produces silicon carbide (SiC)-based power modules across five product families: EV charging systems (AC-DC and DC-DC converters from 18kW to 120kW in both air- and liquid-cooled variants), energy storage and DC microgrid bidirectional modules enabling V2G operation, electrolyzer power supplies for green hydrogen production (PEM and alkaline, 60kW-100kW), DC-DC modules for data center and AI compute applications (62.5kW), and converters for solid oxide fuel cell (SOFC) systems. Modules support CCS1/CCS2/CHAdeMO/GB/T standards, CAN/RS485/Modbus/OCPP communications, voltage ranges up to 2000V, conversion efficiencies of 97-99%, and MTBF exceeding one million hours. Maxwell holds 575 patents, operates with 320 total employees including 235 engineers, and claims deployments across 95+ countries with 400+ partners. Certifications include CE, UL, TUV, EMC, DEKRA, RoHS, UKCA, and REACH.
The company operates an OEM/ODM business model, selling configurable modules directly to charging station builders, BESS integrators, hydrogen electrolyzer system manufacturers, and data center power system OEMs, with quote-based pricing rather than list pricing. Distribution combines direct OEM engagement with channel/reseller support, most notably through Accraine Ltd, which operates the UK Sales Center serving European customers. Go-to-market relies heavily on industry exhibitions (Power2Drive Europe, EVCS & EXPO, EVS34, GIMC), downloadable product catalogs on its website, and news/thought-leadership content targeting emerging-market EV charging, BESS, and hydrogen themes. Revenue is not publicly disclosed, and the company appears to be founder/management-controlled with Shijiazhuang municipal government support rather than venture- or PE-backed.
