The MCS charging controller combines IP65 protection, 1,500 V DC isolation withstand, SIL 1-certified safety monitoring and the open-source EVerest charging stack.
chargebyte has introduced Charge Control Y, or CCY, a charging controller designed for stations based on the Megawatt Charging System.
The controller is intended for heavy-duty charging sites including truck depots, ports, logistics centers, industrial facilities and truck stops.
chargebyte says the CCY is available immediately for new charging-station designs and for integration as a replacement controller in compatible existing equipment.
The product combines an IP65-rated enclosure, five waterproof M12 connectors, reinforced galvanic isolation and a dedicated safety processor. It is developed and manufactured in Germany.
Charge Control Y is built for demanding MCS environments
Heavy-duty charging equipment may operate outdoors and in industrial environments where dust, moisture, temperature changes and continuous use place additional demands on control hardware.
The CCY’s IP65-rated enclosure is dust-tight and designed to protect against water jets. Five waterproof M12 connectors use screw or push-pull locking to secure external connections.
chargebyte specifies an operating-temperature range of −40 °C to +70 °C. The controller supports relative humidity from 5% to 95%, provided the moisture is non-condensing.
The CCY is also designed to operate at altitudes of up to 2,000 meters.
“Megawatt Charging is the key to electrifying heavy-duty transport, where every hour of availability counts,” said Antonio Krüger, Chief Commercial Officer at chargebyte.
“That is why we developed and built the Charge Control Y for continuous operation under harsh environmental conditions: rugged, protected against high-voltage faults and with safety monitoring that detects problems before they lead to downtime.”
Galvanic isolation protects connected charging systems
The Charge Control Y uses reinforced galvanic isolation under IEC 60664-1 to separate the vehicle interfaces from the charging station’s control system and network.
According to chargebyte, this architecture is intended to protect the backend, PROFINET connection and other connected components if a charging-cable fault introduces high voltage onto the signal lines.
The company specifies a voltage withstand of 1,500 V DC for 60 seconds and a rated impulse voltage of 4 kV.
“In heavy-duty applications, robust specifications are what count,” said Dr. Stefan Nagel, Chief Technology Officer at chargebyte.
“IP65 protection, a temperature range of −40 °C to +70 °C and galvanic isolation that withstands 1500 V DC: the CCY is designed for the conditions under which megawatt chargers actually operate.”
These ratings apply to the Charge Control Y itself. The safety and environmental performance of a complete charging station will also depend on its wider system design, integration, installation and connected components.
Safety processor monitors charging signals and temperature
The CCY includes a dedicated Renesas RA2E1 safety processor.
The processor monitors:
- CE and ID charging signals
- Emergency shutdown
- HV Ready outputs
- Temperature inputs
- Temperature-sensor diagnostics
Up to four PT1000 sensors can monitor temperatures at the DC connector, within the power electronics and in the charging station’s cooling system.
If a monitored temperature becomes too high, the controller can reduce charging power or initiate a shutdown. Sensor diagnostics are intended to identify faulty temperature sensors.
The HV Ready outputs use a double relay.
chargebyte says the SIL 1-certified safety concept under IEC 61508 can reduce the qualification effort required for the complete charging system.
The SIL 1 certification applies to the announced safety concept. It should not be interpreted as certification of every function within a complete charging station.
Remote updates could reduce onsite service visits
The Charge Control Y allows the safety processor’s firmware to be updated remotely through the main processor.
chargebyte says remote updates can reduce the need for onsite service visits. The controller also logs temperature data to support predictive-maintenance activities.
An integrated user interface is intended to simplify installation and servicing.
The announcement does not quantify the expected reduction in service visits or provide operating results from deployed MCS stations. These benefits should therefore be understood as intended product capabilities rather than measured field outcomes.
CCY supports EVerest, ISO 15118-20 and OCPP 2.1
The Charge Control Y uses an NXP i.MX93 dual-core processor with two Arm Cortex-A55 cores operating at up to 1.7 GHz.
The controller includes:
- 1 GB of LPDDR4 memory
- 8 GB of eMMC storage
- EdgeLock Secure Enclave
- Trusted Platform Module security chip
chargebyte lists support for:
- IEC 61851-23-3
- ISO 15118-20:2022/Amd 1:2026
- OCPP 2.1
- Plug & Charge
- 10BASE-T1S
- PROFINET
- CAN
The CCY is based on the open-source EVerest charging stack and includes a maintained Yocto Board Support Package.
chargebyte says the open architecture allows charging-station manufacturers to retain control over their software rather than relying on a closed charging stack.
