== Introduction

The http://www.lgchem.com/global/ess/ess/product-detail-PDEC0001[LG Resu 10 LV] Energy Storage System is a very compact, residential Lithium Ion battery made by LG Chem. The lgresu monitoring system can be adapted to work with other CANBus based Lithium Ion Battery Management Systems (BMS)(for example http://discoveraes.com/[Discover AES] batteries).

== Monitoring

The lgresu project provides a server and web based monitoring system to visualize the main LG Resu 10 LV BMS metrics such as:

• State Of Charge (SOC)
• State Of Health (SOH)
• Voltage
• Current
• Temperature.

== Operation

The lgresu server also supplies the LG Resu 10 LV battery with a 'keep-alive' CANBus message which enables the use of a 48VDC inverter without a CANBus connection to the LG Resu 10 LV.

== Hardware

lgresu software requires a Raspberry PI equipped with a CANBus module connected to a LG Resu 10 battery:

More details about the hardware can be found in link:https://github.com/jens18/lgresu/blob/master/doc/LGResuMon.adoc[LGResuMon.adoc].

This solution can coexist with other products for integration of the LG Resu 10 battery with an inverter (Schneider Conext Bridge, Victron ESS, SMA Sunny Island, ...).

It is also possible to connect this hardware to a car CANBus with an ODB2 to RJ45 adapter cable.
