Heliox

What Heliox does

Heliox BV is a Netherlands-based designer, manufacturer, and service provider of DC fast charging systems for electric vehicles, operating as a wholly-owned subsidiary of Siemens AG following its January 2024 acquisition. The company's product portfolio spans portable 40kW Mobile chargers, the modular Flex system (180kW to 360kW), the Flex Pro (480kW) high-power charger, the 44kW bidirectional Vehicle-to-Grid DC charger, and the VersiCharge Blue 80A Level 2 commercial AC charger. Its modular architecture allows dynamic power distribution in 80kW increments across up to six outlets from a single power cabinet, with software services including Chargesight real-time monitoring, energy management, and dynamic load management that recalculates available power every minute to optimize charging under grid constraints. The technology supports CCS1, CCS2, J1772, and inverted pantograph configurations, and integrates standards including OCPP 1.6J and ISO 15118-2/20.

Heliox serves electric bus fleets, electric truck fleets, electric passenger vehicles, marine/port/mining operations, and electric school buses. Its go-to-market is enterprise direct sales targeting transit agencies, logistics operators, and fleet managers across the Netherlands, Germany, Portugal, the United States, Canada, the UK, France, Belgium, Spain, Sweden, Denmark, Norway, and India. Revenue is generated through hardware sales (one-time capital expenditure on Mobile, Rapid, and Flex systems), tiered service and maintenance contracts, the Chargesight subscription software (EU-only), managed energy services including V2G, and a Charging-as-a-Service offering powered with Fleete that converts upfront CAPEX into monthly OPEX payments. The company maintains 300+ employees worldwide with production and R&D in five countries, and reports an installed base powering 25,000+ vehicles daily across 150+ cities.

Recent moves7 records

Expansion highlights6 records

Broad incumbents

• Siemens eMobility: Heliox's parent/merged business unit and the largest European-headquartered EV charging infrastructure provider, offering AC and DC charging hardware from residential up through megawatt-class systems. They are being combined into a single legal entity with Heliox, but historically competed in depot and HPC charging.
• ABB E-mobility: Global incumbent in EV charging infrastructure offering DC fast chargers from 50 kW through megawatt systems, with strong transit and commercial vehicle references. Competes with Heliox on large depot and high-power fleet deals and has substantially greater installed base and balance sheet.
• ChargePoint: Largest US-headquartered EV charging network with broad AC/DC portfolio and a strong software/services platform. Competes with Heliox in North American commercial fleet depot deployments and on the software/Chargesight layer.
• Schneider Electric EV Charging: Diversified industrial player with an EV charging portfolio spanning residential, commercial, and fleet/depot applications. Competes broadly with Heliox in commercial and depot charging and is also referenced alongside Heliox in port charging solutions.

Direct peers

• Kempower: Finland-based DC fast charging hardware specialist targeting electric trucks, buses, and commercial fleets with a modular, dynamic-power-distribution architecture (Kempower Satellites). Direct head-to-head competitor to Heliox's Flex family in the European fleet depot segment.
• Tritium: Australia-origin DC fast charger manufacturer (now majority-owned by Exicom) selling modular high-power chargers for fleets, transit, and public charging. Direct competitor to Heliox's Flex and Rapid product lines, particularly in North America and Europe.
• Allego: European public and depot charging network operator using third-party hardware to deliver charging-as-a-service. Overlaps with Heliox's CaaS offering through Fleete and competes for similar transit and fleet customers in the EU.
• EVBox: European EV charging hardware and software vendor (now part of ENGIE) with AC and DC products aimed at commercial, fleet, and public charging. Competes with Heliox in commercial depot and AC Level 2 fleet applications.

Emerging players

• Nuvve Holding: US-listed V2G platform company focused on bidirectional charging for school bus and commercial fleets. Direct competitor to Heliox's V2G school bus initiative with Hubject and Accelera, though Nuvve is software-led and asset-light relative to Heliox's hardware platform.
• Wallbox: EV charging hardware maker with bidirectional (Quasar) capability for residential and light commercial use. Partial overlap with Heliox on V2G technology direction, though Wallbox is more oriented toward residential/small commercial while Heliox targets heavy-duty fleets.
