The most interesting battery in the world is the one already in a landfill. Or, in the case of a BMW i3, the one sitting in a warehouse after its first life on the road. BCS Supply, a quiet German company operating out of Landshut, has built a business on the premise that these batteries are not waste, but a pre-assembled, high-quality asset. Their job is to make them useful again, with a control system that treats a stack of second-life BMW packs as a plug-and-play building block for the grid.
The Wedge Is a Partnership
The company's entire proposition hinges on a relationship most startups would kill for: a direct line to BMW. BCS Supply says its core Battery Control Solution was developed together with the automaker, specifically for the i3's battery pack [BCS Supply About Us, Unknown]. This isn't scavenging from scrapyards. It's a formalized channel, starting with batteries from BMW's factory in Dingolfing, Germany [BCS Supply About Us, Unknown]. For BCS, the wedge is that partnership. It allows them to offer system integrators and manufacturers a standardized, vetted component, complete with the software to manage it, bypassing the years of R&D and supplier qualification typically required to build a stationary storage product from scratch.
From Pilot Projects to a Saudi Subsidiary
BCS Supply is not just selling kits. It markets complete solutions, from project planning and energy management to system integration and monitoring [BCS Solutions LinkedIn, Unknown]. The company claims its first industrial customer successfully rebranded the BCS solution for the commercial and industrial market, though it doesn't name them [BCS Supply About Us, Unknown]. Its public traction story is told through geography: pilot projects at gas stations in China, utility applications in the UK, and the recent formation of a Saudi Arabian subsidiary, BCS Supply KSA, to pursue engineering and construction projects in Gulf countries [BCS Supply About Us, Unknown]. The most cited metric is an estimated 100 MWh of batteries in use, a figure reported on the company's German site [BCS Solutions, Unknown].

The Solo Founder and the Unseen Balance Sheet
Leadership appears concentrated in founder and CEO Ali Aboosaidi, who is listed as the managing director (Geschäftsführer) of the operating entity, BCS Solutions GmbH [Impressum - BCS Solutions, retrieved 2026]. Public records suggest a solo founder who positioned the company as a supplier-model continuation of BMW's battery-solution vision [FirmLens company profile, Unknown]. What is not visible is any verifiable venture funding, institutional investors, or detailed financials. The company's growth, international pilots, and team of 11-50 employees (estimated) [BCS Solutions LinkedIn, Unknown] appear to be funded off its own balance sheet and presumably, the revenue from its integration work. This presents a clear set of risks and questions.
- The single-source dependency. The entire business is built on a steady, predictable supply of second-life BMW i3 batteries. Any shift in BMW's strategy, battery chemistry, or internal recycling goals could pull the rug out.
- The scale question. One hundred megawatt-hours is meaningful, roughly enough to power 10,000 homes for an hour. But it's a snapshot without a date or methodology. The real test is whether BCS can move from pilot projects to repeat, large-scale deployments that meaningfully dent the gigawatt-hour scale of the global storage market.
- The founder's breadth. A solo founder driving hardware, software, international business development, and a critical automotive partnership is a formidable load. The absence of publicly named senior executives in engineering or sales raises questions about the depth of the bench for the next phase.
The Unit Economics of a Second Life
The fundamental calculation for any second-life battery play is cost per stored kilowatt-hour over the system's lifetime, stacked against the falling price of new lithium-ion cells. BCS Supply's bet is that its BMW-sourced packs, coupled with its standardized integration layer, hit a sweet spot for commercial and industrial customers where upfront cost matters more than absolute peak efficiency. If a used BMW pack costs a fraction of a new one from CATL, and BCS's control system makes it simple to deploy, the total system economics could work even if the battery's remaining capacity is only 70-80%.
For BCS Supply to prove its model isn't just a clever niche, it must eventually compete not with other second-life startups, but with the incumbent it enables: the large-scale battery storage integrator building with brand-new cells. Its control system and partnership are the moat, but the castle needs to be built on volume that matters to the grid. The next twelve months will show if the Saudi foray and unnamed industrial customers are the beginning of that scale, or the limits of it.
