Kempower Station Charger Version 2

DC EV charger

Kempower Station Charger Version 2 combines one or two cabinets, one to eight 50 kW Power Modules and up to two integrated DC outputs. Optional external charging points can bring the total to four. C500 and C800 modules serve different voltage envelopes, while dynamic or dynamic-ready distribution determines how power reaches connectors. Kempower directs third-party management through its OCPP and API documentation. EpiSensor Edge measures each cabinet's AC supply through a ZEM-65 electricity monitor.

Compatibility

Compatible with EpiSensor Edge through a ZEM-65 on each cabinet supply

Kempower directs third-party backends to its OCPP and API integration documentation. Edge does not speak OCPP, so that link stays with ChargEye or the chosen backend. Edge measures each cabinet through an EpiSensor ZEM-65 electricity monitor with Rogowski coils on its three-phase mains supply, which records the energy, power and current per phase it draws.

Station Charger Version 2 with Power Module V2, single or double cabinet; Version 1 and North American configurations differ. Confirm C500 or C800 modules, distribution type, outputs, optional AC socket and meters. Site check: put one ZEM-65 on each cabinet's feeder, with Rogowski coils sized to that feeder and a supply within 110 to 480 V AC line to line.

Optional onward data
A qualified electrician fits Rogowski coils sized to the feeder around L1, L2 and L3 of each cabinet's supply and connects the ZEM-65's voltage reference. Where a double cabinet has two feeders, each takes its own ZEM-65. The ZEM-65 sends energy, power and current per phase over the EpiSensor wireless network to the Gateway, where Edge records them. This is the cabinet's AC input, including conversion losses; DC energy per output stays with Kempower's meters and the backend. The customer-platform output is optional; Edge remains the local system of record.

Specifications

Version 2 uses Power Module V2 in single- or double-cabinet form. Site output is set by module count, module voltage class, distribution configuration, connector ratings and the vehicle request.12

Power modules
One to four 50 kW modules per cabinet; single cabinet up to 200 kW, double cabinet up to 400 kW12
DC outputs

Interface

Documented measurements and integration boundaries for Station Charger Version 2.

  • C500 and C800 refer to module voltage classes. Record the module type rather than labelling every Station Charger simply as 400 kW.
  • Dynamic distribution reroutes power channels during a session. Parallel C500/C800 connections allocate power in 25 kW steps; series-connected C500 modules with adaptive voltage allocate in 50 kW steps. Dynamic-ready fixes the routing until the distribution module is replaced. ChargEye can use even sharing or a configured priority, such as arrival order.
  • Integrated energy meters, an AC Type 2 socket and external charging points are options. Do not assume they are present from the cabinet name.

Assessment

Station Charger Version 2; exact module, distribution, output and backend configuration must be confirmed.

InteroperabilitySupported with conditions
Kempower documents a third-party OCPP/API backend process; Edge measures each cabinet's AC supply through a ZEM-65.3
AccuracyNot yet assessed
Integrated energy meters are optional and the retained public pages do not state their accuracy or billing approval.
SecurityNot yet assessed
The retained public material does not state the OCPP security profile, credential lifecycle or certificate configuration.
ReliabilitySupported with conditions
The manual identifies dynamic routing, installation tests and manufacturer commissioning, while network fallback and session recovery require site evidence.23
RuggednessNot yet assessed
The retained version page does not publish complete enclosure, temperature and impact ratings for every product-code configuration.
ScalabilityWell supported
One or two cabinets, up to eight modules and up to four charging points provide documented staged capacity and dynamic allocation.12
LifecycleSupported with conditions
Kempower maintains a current technical portal and requires certified installation; version and configuration records remain essential for replacement.2

Setup

  1. Confirm the Version 2 label, single- or double-cabinet arrangement, C500/C800 module type and count, dynamic or dynamic-ready distribution, integrated and external outputs, meters and optional AC socket.

  2. Have Kempower-certified and electrically authorised personnel verify foundations, three-phase supply, protection, cable routing, Ethernet tests and local inspection requirements.

  3. Agree the backend and obtain Kempower's OCPP/API documentation and integration support.

    Record charge-point and connector identities before onboarding the charger.

  4. For each connector, compare state, requested and delivered power, session energy and timestamps at the charger and backend.

    Repeat with several vehicles to check the configured sharing or priority. Use the ordered C501/C801 and Ds2/Ds4/R table: for example, the four-module C501 Ds4 configuration is limited to 160 kW per point at 400 V despite its 200 kW cabinet total. Its adaptive 800 V mode has a different limit. Confirm total connector power also stays within the installed module capacity and site limit.

  5. Test loss and restoration of Ethernet or cellular service and the approved backend.

    Record the observed fallback rather than inferring it from OCPP support.
