E-Mobility Charging Infrastructure

EVAcharge Charging Communication Solution

As a “ready-to-use solution” the communication controller consists of hardware and AKKA DualStack software and is available as:

  • Supply Equipment Communication Controller (SECC)
  • Electric Vehicle Communication Controller (EVCC)

Since 2011 AKKA has been further developing the solutions for DC charging communication between electric vehicles and charging stations for rapid charging processes taken over from Auronik GmbH. The ECommStack is DIN70121 and ISO15118 compliant as a DualStack since 2018.

‘’ We are a leading solutions provider for the charging communication technology between electric vehicle and charging spot. ‘’

Our competence is your advantage

  • We have many years of well-founded experience along the entire HW & SW development & production cycle for charging communication, i.e. from specification, development and testing to commissioning.
  • Standardization committees ISO15118
  • SW architecture, design and development (DIN70121, ISO15118, IEC61851)
  • Test design, definition of test requirements, development of test cases and SW validation
  • Backend integrations for operations

Many well-known manufacturers of charging points and electric vehicles use our EVAcharge charging communication solution.



The DualStack is the further development of the ECommStack for standard-compliant communication between charging station and electric vehicle:

  • ISO15118 and DIN70121 compliant communication
  • DC-Charging
  • Can be ordered as EVSE and EV Version
  • Integrated TLS 1.2 Safety
  • Implemented Protocols: TCP/IPv6, SDP, V2GTP
  • Support of External Identification Means (EIM) und ISO Value Added Services (VAS)
  • High-level communication via Green-Phy Powerline
  • Communication with customer software / power electronics via CAN interface
  • Integrated SW update function
  • Only to be ordered with EVAcharge Hardware
  • On request: OCCP protocol for backend connection, OPP protocol for charging communication via WiFi, Plug & Charge and customer-specific adaptation of the DualStack


EVAcharge represents the 7th generation of PLC communication hardware. The main advantages over the previous product are a smaller form factor, the integrated PLC Qualcomm GreenPhy chip.

  • CAN interface
  • Ethernet interface and extension header for customer specific developments
  • RS232 interface
  • USB interface
  • Power line communication (PLC) via control pilot (CP)
  • PWM LowLevel communication, integrated PWM coupling circuit
  • Industry Standard Quality
  • Dimensions 100 x 120 mm

E-vehicle simulator and conformity tester

DC.chargeSTRESSOR Service

As an EV-simulator and conformance testing device, the DC.chargeSTRESSOR ensures interoperability between a charging station (EVSE) and an electric vehicle (EV). It enables the development of standard-compliant charging stations without the need for a real EV.

We offer a DC.chargeSTRESSOR service on site. As a professional service we help you on site with equipment and experts.
