The Big Four EV Charger Manufacturers Compared (Sep 2025 Update)

Key Points

• ABB E-mobility and Alpitronic have established themselves as the dominant forces, each delivering over 4.5 TWh of energy by September 2025.

• Kempower demonstrates the strongest expansion trajectory with 22% energy growth, leveraging their specialized focus on depot charging solutions for commercial fleets.

• Ekoenergetyka maintains stable operations at a smaller scale.

Transparency is slowly becoming the new standard in eMobility. Over the past year, several leading charger manufacturers have started publishing their performance data, a welcome shift that helps the industry benchmark real progress.

In this update, we take a closer look at the four largest non-Tesla DC fast charger manufacturers: ABB E-mobility, Alpitronic, Kempower, and Ekoenergetyka. Together, they are driving a significant portion of the world’s charging infrastructure rollout.

Market Position Analysis (September 2025)

1. ABB E-mobility - Market Leader

• Energy delivered: 4.59 TWh (increased from 4.1 TWh in July)

• Infrastructure scale: Approximately 69,000 DC chargers deployed worldwide

• Usage volume: 179.5 million charging sessions (up from 171.1 million in July)

• Global reach: Operations across 109 countries

ABB maintains its position through sheer scale and geographic penetration, with the largest deployed charging network outside of Tesla.

2. Alpitronic - The Rising Challenger

• Energy delivered: 4.5 TWh (increased from 4.0 TWh)

• Infrastructure scale: Approximately 44,000 chargers deployed (significant expansion from 37,500 in July)

• Usage volume: 150 million charging sessions (up from 130 million)

• Global reach: Present in 52 countries

Alpitronic shows the most aggressive expansion in charger deployment, indicating substantial investment in infrastructure scaling.

3. Kempower - The Growth Leader

• Energy delivered: 1.2 TWh (increased from 0.98 TWh)

• Usage volume: 31 million charging sessions (up from 26 million)

• Global reach: Operations in 65 countries

• Strategic advantage: Specialized focus on depot charging for buses and commercial vehicles

Despite smaller absolute numbers, Kempower's growth rate outpaces all competitors, suggesting effective market positioning in high value segments.

4. Ekoenergetyka - The Regional Specialist

• Energy delivered: 0.139 TWh (marginal increase from 0.138 TWh)

• Infrastructure scale: Approximately 10,000 chargers

• Usage volume: 4.13 million charging sessions

• Global reach: Present in 40 countries

Ekoenergetyka represents the regional approach to market development, maintaining steady operations within their established territories.

Industry Implications

This data transparency trend signals a maturing industry where performance metrics are becoming standardized benchmarks. The willingness of manufacturers to publish these figures suggests growing confidence in their market positions and a shift toward more competitive, data-driven business practices.

The emergence of clear market tiers, from ABB's massive scale competing neck and neck with Alpitronic (who appears to have momentum for the coming years), to Kempower's specialized growth strategy, indicates that the industry is moving beyond the early experimental phase toward established competitive dynamics.

Note: Tesla Supercharger network data is not included in this comparison as Tesla maintains different reporting standards.
