en.Wedoany.com Reported - Chinese energy storage manufacturer JD Energy is bringing its experience in high-voltage transmission infrastructure to the European market, seeking to expand its presence on the continent. Martin Liu, Vice President of Overseas Business, stated that the leadership team has decades of experience in ultra-high-voltage transmission before shifting to energy storage, a background he believes can set JD Energy apart from competitors.
JD Energy was co-founded in 2018 by a renowned power electronics expert and a group of experienced engineers, each with over a decade of experience in developing advanced energy storage technologies. The company focuses on the R&D and commercialization of core technologies and products for advanced battery energy storage systems. Martin Liu explained that the leadership's extensive experience in advanced power systems, power electronics, and grid technology translates directly into energy storage systems that support modern power grids.
JD Energy has already provided grid-forming technology and obtained certifications for grid-forming, black start, and off-grid operation. Liu stated that the company expects to commission its first grid-forming project in Germany by the end of the year. At The smarter E trade fair in Munich in June, the company showcased its product portfolio, including the eBlock series of commercial and industrial cabinets in various capacities, and the newly launched 6.2 MWh Galaxy-2 energy storage system. Subsidiary StrPower also demonstrated solid-state transformer products at the fair.
According to Liu, the technical rationale behind JD Energy's containerized BESS solution is that it avoids self-charging and self-discharging losses found in traditional centralized container designs, where multiple battery racks share a single DC bus and centralized power conversion system. In such layouts, even when the system is off, current flows from racks with higher state of charge to those with lower state of charge, accelerating degradation. JD Energy adopts a distributed architecture with a string PCS beneath each battery rack, which Liu claims enables 100% depth of discharge while avoiding circulating currents.
In terms of safety, Liu stated that JD Energy equips each individual battery cell with sensors, rather than the industry standard of five to seven sensors per battery rack, and feeds voltage, temperature, and current data into an AI-based cell health system designed to issue alerts before thermal anomalies escalate. He also noted that the system has passed third-party fire propagation tests, with a four-hour delay between a single cell thermal event and spread to adjacent battery packs, providing operators time to intervene. Another safety claim is based on integrating the battery management system and PCS into a single unit, which the company says eliminates communication delays that can occur when the two systems are sourced separately and must exchange trip signals in real time.
Since launching its export business in 2022, Germany has been one of JD Energy's key international markets. Liu said the company has now shipped to over 10 countries, including Italy, Germany, the Netherlands, Hungary, and Japan. JD Energy reports that global total delivery capacity has exceeded 10 GWh since the launch of its integrated liquid-cooled energy storage system in 2022. The company has invested in localized teams to support European operations, with an office in Düsseldorf, Germany, and an after-sales service center in Hungary covering the entire European market. Deals are ongoing, including a strategic agreement for approximately 1 GWh signed during The smarter E trade fair in Munich. Liu said that from 2022 to the present, the company has delivered over 2,000 projects with a total capacity exceeding 10 GWh, expressing strong confidence in promoting its products in Germany and Europe.
