Romania’s Prime Batteries teams with Arrow and NXP on 1,500 V battery storage platform

Romania’s Prime Batteries Technology has unveiled a high‑voltage battery energy storage system platform in collaboration with Arrow Electronics and NXP Semiconductors. The announcement was issued on May 13.

The platform supports up to 1500 V. It is built to meet European functional safety standards such as ISO 26262 and IEC 61508 SIL 2. The press release highlights modular design and multi‑layer protection. It also notes continuous, independent cell monitoring. No details were given on storage capacity, system format or price.

Prime Batteries runs a 2.3 GWh lithium‑ion cell plant near Bucharest, in Cernica. Its products have appeared in local projects for Hidroelectrica and the Monsson Group. The company has focused on cell manufacturing and project‑specific battery packs before pushing into integrated storage platforms.

Romanian news outlet Profit.ro said earlier in May that Prime Batteries had purchases around two hectares of land in 2024, located about 200 meters from its existing factory, to build a new factory. The outlet reported the build would include three buildings, one with three floors, another with two floors and a production and storage hall.

According to the press release, Arrow Electronics will handle engineering integration and supply chain. The company has a track record in electronics distribution and system integration worldwide. Its involvement could help Prime meet certification requirements more swiftly, and speed up deliveries.

NXP Semiconductors contributes a 1,500 V BESS reference design. This includes pre‑certified safety libraries and documentation for IEC 61508 SIL 2 and IEC 60730 Class B. NXP’s package is meant to reduce development time. It may also help secure ASIL D certification if required.

Vitali Damasevich, director engineering Eastern Europe and engineering solutions center EMEA, Arrow Electronics, said, “We are delighted to work with NXP and Prime Batteries to support the delivery of this cutting-edge BESS solution. By combining our engineering expertise and supply chain capabilities, Arrow and NXP are supporting Prime Batteries in enabling the rapid deployment of energy storage systems that will drive the transition to a cleaner and more resilient energy grid.”

Vicentiu Ciobanu, CEO of Prime Batteries, said, “Our collaboration with Arrow and NXP has resulted in a BESS platform that not only helps meet the highest safety standards but also offers flexibility, scalability, and cost-effectiveness. This solution will undoubtedly accelerate the adoption of renewable energy and contribute to a more sustainable future.”

The timing of the announcement comes directly after The Smarter E trade show, where Prime Batteries had a stand. The news was instead announced four days later. Key questions remain; Prime did not disclose a production schedule or installation targets and there is no information on pilot installations or customer orders. The company also declined to offer insight into cost competitiveness.
