What E4V does
ARTS Energy, operating as E4V, is a French battery manufacturer headquartered in Nersac (10 rue Ampère, 16440) with commercial offices in Paris (6 rue Duret, 75116), employing 101-250 staff. The company designs and produces both standard and custom battery packs across four chemistries — Li-ion, LiFePO4, Ni-MH, and Ni-Cd — targeting electric mobility applications including e-bikes, e-boats, and stationary storage, as well as medical, solar, air transport, professional tools, safety lighting, and IoT devices. Its manufacturing footprint is concentrated in France, with a sales channel combining direct enterprise engagement and a regional distributor network.
The company differentiates on a multi-chemistry platform approach, designing application-specific packs rather than standardizing on one cell type. Its technology stack includes IoT-connected batteries with real-time monitoring, and a full-service custom development offering that spans personalization, industrialization, and certification management. The company does not disclose any AI/ML capabilities, R&D publications, or proprietary algorithms in the input data; its core technical positioning rests on cross-chemistry expertise, French manufacturing ('Fabrication française'), and end-to-end certification handling. The four chemistry lines each have dedicated product pages, suggesting deliberate merchandising rather than implicit inventory carry.
E4V's commercial model is B2B enterprise project-based: customers engage the company to develop bespoke battery solutions, with E4V absorbing development, industrialization, and certification work so that the customer can focus on its own application. Revenue is generated from hardware sales (standard and custom packs) and embedded customization services, with project pricing handled through direct quotation rather than public list pricing — pricing is not publicly disclosed. Distribution is bimodal: direct enterprise sales for custom projects and a regional distributor network for standard products. The customer base is not disclosed in the source data, and no named logos, revenue figures, or financial KPIs are available.
