Of 355 companies in our database, 280 maintain active websites and 268 have verified contact information from Swedish business registry records.

Manufacturing & Production Leaders

Cell & Module Manufacturing

[Kedali Sweden AB](https://www.sourceregister.com/sv/battery-storage/supplier/kedali-sweden-ab), based in Skellefteå in northern Sweden, represents the sector's industrial backbone. Established in 2020 with 9,000 employees, Kedali Sweden AB operates as the world's largest manufacturer of lithium-ion battery cases and housings. The company's scale provides Swedish procurement managers direct access to cost-competitive, high-volume production. Skellefteå's strategic location offers proximity to hydroelectric power for energy-intensive manufacturing, a critical advantage in Sweden's cost structure.

[Envirotainer Engineering Aktiebolag](https://www.sourceregister.com/sv/battery-storage/supplier/envirotainer-engineering-aktiebolag) operates from Sollentuna, just north of Stockholm, with an established production footprint dating to 1987. The 500-person operation focuses on battery and accumulator manufacturing, serving both OEM and aftermarket channels. The company's three-decade operating history indicates reliable supply chain management and quality consistency.

[EV Nord AB](https://www.sourceregister.com/sv/battery-storage/supplier/ev-nord-ab), based in Alnö, operates as a specialized battery cell manufacturer. Though smaller in headcount, the company's focus on battery production serves niche applications in the Swedish market.

Electrical Components & Systems

[Charge Node Europé AB](https://www.sourceregister.com/sv/battery-storage/supplier/charge-node-europe-ab), located in Mölndal near Göteborg, was established in 2018 with 70 employees. The company manufactures specialized electrical apparatus, positioning itself within the rapidly growing EV charging and grid interface sector. Mölndal's location in the Göteborg industrial corridor provides access to advanced manufacturing ecosystems and technical talent.

[Berlex i Kungälv Aktiebolag](https://www.sourceregister.com/sv/battery-storage/supplier/berlex-i-kungaelv-aktiebolag) has operated since 1972 from Kungälv, demonstrating sustained operational presence in electrical equipment manufacturing. The company's manufacturing capabilities cover electrical apparatus production relevant to energy storage integration.

Energy Utility & Strategic Partners

[Vattenfall AB](https://www.sourceregister.com/sv/battery-storage/supplier/vattenfall-ab), headquartered in Stockholm with 21,000 employees, operates as far more than a traditional utility. The company functions as a research and industrial partner embedded within the European battery supply chain's R&D ecosystem. Vattenfall's scale, technical resources, and grid access make it a critical reference point for procurement professionals evaluating energy storage integration, grid services, and large-scale deployment scenarios.

Testing, Certification & Technical Analysis

The energy storage sector requires rigorous third-party validation. [5 ARC Consulting AB](https://www.sourceregister.com/sv/battery-storage/supplier/5-arc-consulting-ab), established in Skene in 2014, provides technical testing and analysis services. Similarly, [AB Certifikator](https://www.sourceregister.com/sv/battery-storage/supplier/ab-certifikator) based in Brännö offers technical testing and analysis specifically for battery storage and energy storage applications.

Additional testing capacity exists through [A analys AB](https://www.sourceregister.com/sv/battery-storage/supplier/a-analys-ab) (Stockholm, established 2015) and [ALOMA Teknik AB](https://www.sourceregister.com/sv/battery-storage/supplier/aloma-teknik-ab) (Stockholm, established 2013). These services address critical procurement requirements: performance validation, safety certification, thermal management analysis, and cycle-life assessment.

Specialized Manufacturing

[ALSTOM Rail Sweden AB](https://www.sourceregister.com/sv/battery-storage/supplier/alstom-rail-sweden-ab), based in Västerås since 1966 with 20 employees, manufactures specialized electrical apparatus for rail and transport applications. While focused on mobility rather than stationary storage, ALSTOM's technical expertise addresses energy storage requirements within the transport sector.

[Chikara Advanced Electronics Aktiebolag](https://www.sourceregister.com/sv/battery-storage/supplier/chikara-advanced-electronics-aktiebolag), operating from Åtvidaberg since 1997, provides electrical apparatus manufacturing with specialized electronics integration capabilities.

Geographic Procurement Considerations

Stockholm (42 companies): Concentration supports rapid supplier evaluation and technical meetings. Companies cluster around technology, testing, and systems integration services. Access to skilled technical talent and proximity to research institutions (KTH, Stockholm University) create ecosystem advantages.

Göteborg (25 companies): Second-largest cluster benefits from proximity to Volvo, other automotive OEMs, and established industrial infrastructure. Port access facilitates international supply chain participation.

Regional Hubs: Västerås (8 companies) and Uppsala (8 companies) host specialized manufacturers serving rail, utilities, and industrial applications. These regions offer cost advantages and established technical workforces.

Northern Concentration: Skellefteå's emergence as global battery manufacturing center (Kedali Sweden AB) reflects deliberate industrial policy and hydroelectric cost advantages. Regional procurement managers should evaluate northern sourcing for high-volume battery components.

How to Choose: Practical Procurement Framework

1. Define Application Requirements Battery storage needs diverge sharply. Grid-scale BESS requires megawatt-hour capacity, fast response time, and long calendar life. Industrial UPS applications prioritize cycle efficiency and reliability. EV charging infrastructure demands different technical specifications than stationary home systems. Clarify your specific application before supplier evaluation.

2. Verify Manufacturing Capacity & Certification All suppliers in our database are verified through Swedish business registry records. Confirm: - Active business registration and payment status - Manufacturing facilities aligned with production volume requirements - Third-party certifications (EN standards, UL, IEC) - Quality management system documentation (ISO 9001 or equivalent)

For large-volume requirements, request facility audits and production documentation. Kedali Sweden AB and Envirotainer Engineering Aktiebolag have established track records; smaller suppliers require more rigorous verification.

3. Evaluate Geographic Access Stockholm's concentration supports rapid supplier engagement and technical collaboration. Göteborg-based suppliers offer manufacturing cost advantages and established quality infrastructure. Skellefteå provides unmatched scale for battery components. Map your logistics requirements against supplier locations to optimize lead times and transportation costs.

4. Assess Technical Support Infrastructure Testing and certification services (5 ARC Consulting AB, AB Certifikator, A analys AB) should be pre-identified if your procurement requires independent validation. Utilities like Vattenfall can advise on grid integration and large-scale deployment scenarios.

5. Verify Supply Chain Continuity Review company founding dates and employee counts. Established operations (Envirotainer Engineering since 1987, Berlex since 1972) demonstrate supply chain stability. Newer companies (Kedali Sweden established 2020, Charge Node Europé 2018) often bring innovation but require closer risk monitoring.
