GENERAL DESCRIPTION
The MG Energy Monitor is an easy to use touchscreen display that shows the status of you MG
Lithium-Ion battery system. The small size and high IP rating makes the MG Energy Monitor suitable
for a wide range of applications. Scrolling through the status pages and changing setting is easily
done by touch.
The Wi-Fi capabilities of the Energy Monitor allow it to communicate with the MG Energy Portal, an
online portal that gives the user the possibility to remotely monitor their battery system.
4.1
Battery system components
MG’s Lithium-Ion battery system consists of the following components:
One or more MG Master HV or LV battery management systems.
One or more Lithium-Ion battery modules, e.g. RS series, LFP series or HE series.
Optionally an MG Energy Monitor.
Consult MG Energy Systems B.V. for compatibility between device types.

Functional description
The main purpose of the Energy Monitor is to show battery system information and parameters.
Secondly it can be used as a gateway to send all the status information to MG’s Energy Portal to
monitor the battery system remotely.
MG’s system philosophy is to have one master BMS, e.g. a MG Master LV or MG Master HV, per
string of battery modules which communicates with one or more slave BMSs integrated in the
Lithium-Ion battery module(s). The slave BMSs are monitoring the battery cell parameters like, cell
voltage, cell temperature. Besides monitoring, the slave BMS also controls balancing of the cells
based on the input of the master BMS.
These parameters are sent to the MG Master via a dedicated CAN-bus which collects all the data and
monitors them. When an MG Energy Monitor is connected to the system it will receive parameters
from both the master and all the batteries in the system. This information is then available on the
Energy Monitor via a series of pages, some of which can be altered to precisely match the users
specific use case.
