What ChengRui does

ChengRui Power Technology (Shanghai) Co., Ltd. (澄瑞电力科技(上海) 股份公司) is a privately held Chinese industrial technology company founded in 2016 that designs and manufactures electrification equipment for ports and shipping. The company is organized around five product lines: port shore power systems (frequency converters from 100kVA to 8MVA, prefabricated cabin power supplies, cable management), ship-side shore power receiving equipment (high/low-voltage connection boards, cable winches), energy storage systems (40ft/45ft lithium iron phosphate containers, bidirectional converters with greater than 99% efficiency, energy management systems), port energy-saving and intelligent equipment (gantry crane regenerative systems achieving greater than 25% energy savings, RTG machine-vision correction systems), and new energy vessel systems (DC/AC distribution boards, marine battery packs, BMS, AC/DC charging piles, containerized mobile power supplies). Its underlying technology stack combines IGBT-based power electronics, three-level converter topologies, active balancing battery management, and IoT-based control platforms; the flagship high-voltage shore power connection distribution board is certified by all seven major international ship classification societies (CCS, ABS, DNV, BV, KR, LR, RINA).

ChengRui operates a B2B enterprise sales motion through a direct field-sales team based out of Shanghai headquarters, supported by an R&D center in Nanjing and a manufacturing center in Nantong. The company sells capital equipment and integrated systems on a project basis to ports, shipyards, shipping operators, and maritime authorities, complemented by after-sales technical services including installation, commissioning, and lifecycle support. Revenue streams are predominantly hardware sales (shore power equipment, new energy ship systems, energy storage systems, port energy-saving/intelligent systems) with a smaller professional services contribution. International expansion is being pursued through the VC Power joint venture with Singapore-based Vallianz, while domestic scale is anchored by deployments on landmark vessels including Offshore Oil 551, Weiqiao Lvdong 1 (the world's first 10,000-tonne-class offshore new energy hybrid bulk carrier), and Huahang Xinneng 1 (China's first Yangtze River branch swap-charge battery-powered container ship). The company has cumulatively delivered over 1,000 shore power systems and related products, exceeding its internal "Thousand Sails Plan" target, and maintains strategic supply-chain partnerships with EVE Energy and CATL E-Ship Technology for battery cell sourcing and co-development.
