Charge Controller

Flea 4 EVSE

Flea 4 EVSE is CarMedialab’s most up-to-date professional charging communications controller. It combines all nece­ssary charging and communication interfaces as well as supervision and analysis logs in a single system. This reduces system complexity and integration costs. In addition, Remote Device Management makes it possible to communicate reliably, in accordance with industry standards, between the charging controller and the charge management system. This enables OTA software updates, a range of payment functions, control functions for operating and costs as well as Value Added Services.

Intelligent charging communication

Drivers of e-vehicles expect charging to work easily. For vehicle and charging point to harmonize, software and hardware need to be perfectly coordinated. CarMedialab develops state-of-the-art technology for standard-compliant communication between charging point and vehicle.

Use Cases

CCS (Combined Charging System)

Both direct current and alternating current charging methods can be i mplemented with the standardized CCS connector system.

Panto Up

With Panto Up, the current collector is located on the vehicle roof and extends upwards in the direction of the charging station.

Panto Down

With Panto Down, the current guide is mounted on the infrastructure and lowers to the roof of the vehicle for charging.

Wireless power transfer

Non-conductive energy transmission through the means of inductive coils.


Equipment for simulating charging processes.
