¶ Introduction
The TC Charger is a robust and compact charger that can be used to charge MG battery systems. It is CAN bus controlled and air-cooled. There is a different range available in voltage and power.
¶ Compatibility
The TC chargers can only be controlled by CAN bus. Therefore the SmartLink MX is required to act as a controller between the MG Master LV/HV and the chargers.
¶ MG SmartLink MX
- Minimum firmware version:
All versions(CAN-A),V1.14 (CAN-A and CAN-B) - Maximum supported chargers:
6
For use on board a vessel it is recommended to use an isolation transformer. It needs at least to be considered.
For parallel operation, units must be ordered with separate ID. Unit ID cannot be field changed or reprogrammed. Similarly if replacement unit is ordered, UNIT ID must be specified at time of order.
¶ Supported chargers
The table below shows the available version of the chargers including article numbers for ordering. All these chargers are CAN bus controlled.

¶ Schematic example
The schematic below shows an system example with TC chargers connected to the MG battery system.
¶ Installation
¶ AC connections
¶ 6.6 kW GEN2 - All versions
¶ DC connections
The DC connector differs on the several versions of chargers available.
¶ 6.6 kW GEN2 - Low Voltage
¶ 6.6 kW GEN2 - High Voltage
¶ CAN bus
For proper operation the use of a CAN bus isolator is required.
To setup CAN bus communication, CAN-H and CAN-L of the TC charger must be connected to the CAN-H and CAN-L of the SmartLink MX:
| Function | MG: CAN-A / CAN-B (RJ45) | TC charger: Molex 334722001 |
|---|---|---|
| CAN-H | Pin 7 | Pin 11 |
| CAN-L | Pin 8 | Pin 12 |
¶ 6.6 kW GEN2 - All versions
¶ MG CAN bus connector details
The TC charger can be controlled on both CAN-A or CAN-B connections of the SmartLink MX.
A MG Energy Monitor or Diagnostic tool will no longer be supported during normal usage if the charger is connected to CAN-B. Settings can then be changed using the MG Connect App (Available for Apple or Android)
For MG CAN bus connector pinout, check the application note: MG CAN bus pinning
¶ Configuration
The SmartLink MX is controlling the connected chargers by CAN bus. The configuration consists of a normal configuration to add the connected Master LV/HV's to the SmartLink MX and a few settings to enable the charger control.
Adding a Master LV/HV to the SmartLink MX configuration:
¶ SmartLink MX
The chargers are controlled by the SmartLink MX. A few settings need to be changed to enable this functionality.
- If the charger is connected to CAN-B of the SmartLink MX, the setting CAN-B CAN bus protocol must be set to
Additional charger protocol. Read below info before changing this setting!
This setting must be changed with the MG Connect App (Available for Apple or Android)
Once this setting is changed, a MG Energy Monitor or Diagnostic tool will not longer be supported on this port.
- Set the
