¶ Introduction
The Delta Q Charger is a robust and compact charger that can be used to charge MG battery systems. It is CAN bus controlled and air-cooled.
¶ Compatibility
The Delta-Q 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:
V1.8 (CAN-A only),V1.14 (CAN-A and CAN-B) - Maximum supported chargers:
6
The EV-functionality is not yet supported by the SmartLink MX
¶ Supported chargers
The table below shows the available versions. All these chargers can be CAN bus controlled.
| Type | Voltage (out) | Current (out) | MPN | Features | Supported by |
|---|---|---|---|---|---|
| XV3300 series | 58V, 65V, 120V | 40, 56A | XV3300-VV1 | IP67 Fan-cooled EV-ready |
1 VV = Voltage rating.

¶ DC connections
¶ DC connector
Connection DC must be used as DC output connection.
| Pin | Function | Wire color |
|---|---|---|
| 1 | Positive (+) | Red |
| 2 | Negative (-) | Black |
¶ AUX-DC connector (optional)
| Pin | Function | Wire color | Notes |
|---|---|---|---|
| 1 | Positive (+) | Red | Configurable from 12-24V |
| 2 | Negative (-) | Black |
This connector has a different key than DC-out
¶ CAN bus connections
To setup CAN bus communication, CAN-H and CAN-L of the Delta-Q charger must be connected to the CAN-H and CAN-L of the SmartLink MX:
| Function | MG: CAN-A / CAN-B (RJ45) | Delta-Q SIG1 connector |
|---|---|---|
| CAN-H | Pin 7 | Pin 3 |
| CAN-L | Pin 8 | Pin 4 |
| CAN-GND | Pin 3 | Pin 9 |

| 12 | Interlock (N.O.) | Interlock (N.O.) |
*CAN 1 and CAN 2 are on the same bus so that two sets of contacts are available for wiring the bus
*Non-terminated at the charger - Install terminator on CAN 2 if needed
¶ Delta-Q SIG2 connector details (EVSE)
The EVSE functionality is yet not supported by the SmartLink MX
¶ MG CAN bus connector details
The Delta-Q 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 controls the charger by CAN bus. The configuration consists of a normal configuration for a standalone or combined battery system and a few settings in the SmartLink MX to enable the charger control.
¶ MG Master LV/HV
Adding a Master LV/HV's to the SmartLink MX configuration:
¶ MG 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.
-
Change the setting Additional CAN bus charger to
Delta-Qand enter the number of chargers in the Number of CAN bus chargers field. -
Set Charge current limit to the highest allowed charge current allowed by the hardware (charger limits, cable size, etc...) .
