Kempower: Modular DC charging and charging-management software

Kempower makes modular DC chargers and ChargEye software for public charging, vehicle fleets and commercial charging sites.

Summary

Best for
Fleet depots and public charging sites needing modular capacity, shared power allocation and coordinated charging operations.
Less suited to
Assuming a charger name settles its installed power modules or that an OCPP management connection is a native building-monitoring interface.
Deployment
Power cabinets, charging points and electrical infrastructure on site, with ChargEye or a compatible charging-management backend.
Data in
Charging sessions, status, schedules and site-load information. ChargEye documents OCPP charger connections, REST APIs and other industry interfaces.
Pricing
Charging hardware, power modules, installation and the chosen software/service level are specified separately.

Overview

Kempower was founded in Lahti in 2017 as a business focused on electric-vehicle fast charging. Its early company account describes its connection to the Kemppi group and a product approach built around the charging user. The current offering combines modular DC equipment with software that manages charging across a site or network.

The distinction between a power cabinet and a charging point is central to the Satellite architecture. Conversion capacity can serve driver-facing units rather than being duplicated inside every dispenser. The Station Charger brings power conversion and the charging interface into an all-in-one arrangement, while retaining modular capacity. ChargEye adds charging operations and energy-management functions. These three layers let an operator compare equipment layout, installed power and the software responsible for running the site.

Offering

The Station Charger uses the same modular cabinet approach as Kempower's Power Unit. Its current product page specifies up to 200 kW in a single cabinet and 400 kW in a double cabinet. It supports up to two integrated charging points, with two further points available through Satellites or Control Units. Additional power modules allow installed capacity to grow with demand.

The Satellite separates the driver interface from the main conversion equipment. This helps arrange charging points around parking spaces or depot lanes while sharing the available power. ChargEye supplies the software layer: monitoring, notifications, power management, scheduling and analytics, with offerings aimed at fleet depots, public charging and retail. The Station Charger page also describes a Load Manager Kit that measures consumption at the grid connection and supplies that information to ChargEye so the site's charging power can follow available capacity.

Technology

ChargEye's developer information documents charger connections over OCPP and access to charging points, transactions and schedules through a REST API. The software overview also names interfaces including OCPI, VDV261, VDV463 and OpenADR. Those interfaces have different roles, from roaming and depot operations to external energy signals; their presence does not make every connected charger expose the same local measurement protocol.

The Station Charger description explains dynamic routing of power channels between charging points and the use of real-time site-load measurements by the Load Manager Kit. This joins electrical capacity management with charging operations. A monitoring design should distinguish that managed charging data from an independent electrical meter on the site's supply. An OCPP backend connection describes charger-to-management communication, not a native building-data import or permission to send operating commands from another system.

Markets

Kempower's software overview identifies public charging, fleet depots and retail environments. Fleet operation adds vehicle schedules and readiness requirements; public charging adds user access, payment and network operation. The developer material describes tools for connecting charging equipment and integrating the management platform with existing operations, including virtual chargers for testing charging and payment flows.

The Station Charger targets sites that benefit from an all-in-one arrangement, including depots with space and cabling constraints. Its optional external charging points provide a path to extend the layout. The Satellite offers a distributed alternative. Choosing between them involves parking layout, vehicle movements, available electrical capacity and expected growth, as well as the charging-management software and service arrangement.

Company

Kempower's articles of association identify the legal name as Kempower Oyj in Finnish and Kempower Corporation in English, with domicile in Lahti, Finland. Its governance page states that the shares are listed on Nasdaq Helsinki and describes governance under Finnish law and the Finnish Corporate Governance Code.

The 2021 company account records establishment in autumn 2017 as an independent fast-charging business associated with Kemppi Group. That is distinct from the older Kemppi welding-equipment business. Kempower's current product organisation combines charging hardware, software, integration tools and service. Its developer offering reflects that combination: the company supports both the physical charging installation and the software connections used to operate it.
