Alpitronic HYC400 Series 2

DC EV charger

HYC400 Series 2 is a European high-power DC charger built from one to four 100 kW SiC stacks. It provides 100 to 400 kW total output, 150 to 1,000 V DC and up to two 600 A continuous CCS2 connectors. Alpitronic lists OCPP 1.6 J and 2.0.1 J between the charger and a charging-management system. Those interfaces serve the CPMS, and EpiSensor Edge measures the charger's AC supply through a ZEM-65 electricity monitor.

Compatibility

Compatible with EpiSensor Edge through a ZEM-65 on the charger supply

Alpitronic documents OCPP 1.6 J and 2.0.1 J between the charger and a CPMS, over Ethernet or cellular networking. Edge does not speak OCPP, so that link stays with the CPMS. Edge measures the charger through an EpiSensor ZEM-65 electricity monitor with Rogowski coils on its 400 V supply, which records the energy, power and current per phase it draws.

European HYC400 Series 2 with 400 V nominal three-phase supply, 630 A maximum input and CCS2 connectors; distinct from the original HYC400 and the North American configuration. Confirm the ordered stack count, connectors, metering option and firmware. Site check: fit 1000 A Rogowski coils (120 mm) around each phase of the feeder.

Optional onward data
A qualified electrician fits 1000 A Rogowski coils around L1, L2 and L3 of the charger's AC feeder and connects the ZEM-65's voltage reference. 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 charger's AC input, including conversion losses and standby; DC energy per connector stays with the charger's own meters and its backend. The customer-platform output is optional; Edge remains the local system of record.

Specifications

The current European product page separates the Series 2 from the original HYC400. Output depends on the number of installed SiC stacks and how the two CCS2 connectors share available power.12

DC output
100, 200, 300 or 400 kW total from one to four SiC stacks; 150 to 1,000 V DC13
Connectors
CCS2, up to two connectors; 600 A continuous per connector in the supported configuration13
Supply and efficiency
400 V nominal three-phase supply, 630 A maximum input; up to 97.7% at full load13
Backend and network
OCPP 1.6 J and 2.0.1 J to a CPMS; Ethernet and cellular network interfaces13
Environment
IP54, IK10, -30 to +55 °C operation; output can depend on environmental limits13
Metering option
Optional DC meters with an additional display for German calibration-law applications13

Interface

Documented measurements and integration boundaries for HYC400 Series 2.

  • Keep charger identity, CPMS charge-point identity, connector identity, stack count and firmware together in the asset record.
  • OCPP session values and commands belong to the selected CPMS contract. Edge records the cabinet's AC supply through the ZEM-65, not connector sessions or billing.
  • German calibration-law DC meters are an option. Confirm the ordered meter and approval boundary rather than treating every HYC400 Series 2 as compliant.
  • With one 100 kW stack, maximum output current is 300 A. Two stacks support 600 A; three stacks support one 600 A plus one 300 A output, or two 450 A outputs. Four stacks support two 600 A outputs within the shared 400 kW total. Power allocation is in 50 kW increments.

Assessment

HYC400 Series 2 European configuration; Edge measures the AC supply through a ZEM-65, with no universal billing claim.

InteroperabilitySupported with conditions
OCPP 1.6 J and 2.0.1 J to a CPMS are named; Edge measures the charger's AC supply through a ZEM-65.1
AccuracyLimited
Power and optional compliant DC metering are described; the installed meter, exposed OCPP values and billing approval follow the order.1
SecurityNot yet assessed
The public pages do not specify the installed OCPP security profile, credential lifecycle or certificate handling.
ReliabilitySupported with conditions
Supply, environmental limits, remote diagnostics and software updates are described; reconnection and fallback behavior require a site test.1
RuggednessSupported with conditions
IP54, IK10, temperature, altitude, humidity and installation form are published for the European unit.1
ScalabilitySupported with conditions
One to four stacks and dynamic allocation across two outputs support staged capacity, subject to site supply and CPMS design.12
LifecycleSupported with conditions
The current platform has remote diagnostics and updates, but firmware history and configuration export need confirmation for the installed fleet.1

Setup

  1. Read the model plate and order record to confirm HYC400 Series 2, the installed stack count, one or two CCS2 connectors, cable length and metering option.

    Record the firmware before changing configuration.

  2. Have an authorised installer verify the 400 V three-phase supply, protective devices, civil base, cable entry, ventilation and manufacturer environmental limits for the ordered maximum input.

  3. Agree the OCPP version, security profile, charge-point identity and endpoint with the CPMS operator.

    Prove charger acceptance at the CPMS before enabling managed charging.

  4. Run a bounded charge on each connector and record DC voltage, current, delivered power and session energy at the charger and CPMS.

    As a calculated example, 400 V × 600 A / 1,000 = 240 kW; a 400 kW cabinet rating does not mean a 400 V vehicle can receive 400 kW. Vehicle demand and allocated stacks can limit it further. Repeat with both connectors active and compare their combined power with the installed stack capacity and configured site limit.

  5. Test network loss, CPMS loss and restart behavior under the approved operating plan.

    An accepted OCPP session is software evidence, not proof of physical power delivery.

Common questions

Can each connector deliver 400 kW at the same time?
No. The published maximum is 400 kW total. With four stacks, two connectors can each deliver up to 600 A, while dynamic allocation shares the available power.13
How does HYC400 Series 2 connect to EpiSensor Edge?
Through an EpiSensor ZEM-65 with 1000 A Rogowski coils on the 400 V supply, which gives Edge the energy, power and current per phase the charger draws. Edge does not speak OCPP, so the OCPP 1.6 J and 2.0.1 J link stays with the CPMS.13
Is every Series 2 charger approved for German billing?
No. The product page describes compliant DC meters and an additional display as an option. Verify the exact ordered meter, certificate and operating process.1
