11. BMS TOOLS
11.1 INTRODUCTION TO THE BMS
The BMS is intended to safeguard the battery and battery cells against a variety of situations that
could damage or destroy system components. This protection also aids in keeping the battery and
battery cells operational for a greater number of life cycles. Each EG4
®
LifePower4 battery is
specifically configured to ensure peak performance and operation with any system.
PCB temperature protection
The BMS will ensure that the Printed Circuit Board (PCB) does not overheat. This is the part that
houses most of the “brains” of the battery. This feature will turn the battery off if it begins to overheat.
Cell balance protection
Cell balance ensures that each cell is within a specific voltage range of each other. Cell balance is
crucial for ensuring that the battery is operating properly for its lifespan. This is always done
automatically.
Environmental temperature protection
It may be dangerous to attempt to use the battery in extreme heat or cold. Continued operation in
these conditions may result in permanent damage to the battery module and its components. To
prevent this, the BMS is designed to measure the temperature while charging/discharging and will
shut down the battery to prevent damage.
Voltage protection
The BMS is designed to continuously monitor the voltage of each individual cell and ensure that they
are not over/undercharged.
Current protection
The BMS is designed to constantly monitor the charge/discharge amperage and has built-in
safeguards against exceeding specific parameters. These include built-in timers that shut off quickly
in the event of short circuits, extremely high amperage, and delayed shut down for amperage that is
only slightly above the maximum capacity.
11.2 BMS TOOLS INSTALLATION AND INTERFACING
The PC software “BMS Tools” provides real-time battery analysis and diagnostics. The battery
cannot communicate with BMS Tools and a closed loop inverter at the same time.
Visit https://eg4electronics.com/resources/downloads
to get the latest version of the software. The
file can be located on the downloads page underneath the product in question.
Once the file has been downloaded, unzip the .zip file. Once the file is unzipped, refer to the
included “Connection guide for BMS Tools V1.0. or V2.2.1.pdf” for an extensive walkthrough to set
up BMS Tools.
If confirmation of the port numbers for battery to PC communications is needed, please consult the
following section.
