Simulation Process:: Our Project Is To Create A BMS (Battery Management System)

The project aims to create a battery management system (BMS) simulation containing a solar panel, 220V AC power source, 20 lithium-ion batteries totaling 36V, an active cell balancing circuit, fuzzy temperature control, state of charge (SOC) estimation, and 350W DC motor load. The simulation involves charging the batteries from the solar panel until they reach 20% SOC, then charging from the 220V AC until 80% SOC before discharging back to 20% SOC and repeating the cycle. Graphs of total battery SOC, voltage and current as well as individual battery voltages over time and SOC over time for each battery will be output to evaluate the cell balancing circuit and SOC estimation performance. Temperature control will also be

Our project is to create a BMS (Battery Management System)

The system (Battery Management system) simulation should contain the ff:

1.) Solar Panel

2.) 220V ac

3.) 20 lithium- ion batteries (36V in total)

4.) Cell balancing Circuit (Active cell balancing)

- A cell balancing is also required particularly the active cell balancing method for the 20 lithium ion
batteries.

5.) Fuzzy Temperature Control

- A fuzzy logic control should also be implemented in the system to avoid overheating of batteries.

6.) SOC estimation

6.) LOAD: DC motor (350Watts Load) or optional a resistor

*We have two power sources, one is the solar panel the other one is a power source representing the
220vAC or outlet.

*For the battery pack consisting of 20 lithium-ion. 10 batteries will be in series for a total of 36V while
the other 10 is in parallel to increase the mAH. Each battery will have 3.6V and 3600Mah. Or you can use
the preset battery in Simulink.

SIMULATION PROCESS:
At the start of the simulation, the SOLAR PANEL is running to increase the runtime of discharging the
battery pack while the load is connected. While the 220Vac is not yet running or connected. The initial
SOC of the batteries is 100%. >>>>>>>

Once it reaches less than or equals 20%, The connection of the solar panel and the load to the battery
pack will be disconnected while the 220vAC will be connected to charge the SOC of the battery pack
until 80%. >>>>>

Once the SOC reaches 80%. The 220vAC will be disconnected while the SOLAR PANEL and the load will
be connected to discharge again the batteries to 20%. And the cycle continuous…
OUTPUT OF THE SIMULATION
Please show a graph of the total soc, voltage, and current of
the batteries
The objectives of this project are:
a.) To extend system run time by balancing the charge during the charging and discharging cycle of
the batteries.

Please show a graph of 20 batteries showing the voltage at a certain time to see
the voltages that they’re not too far from each other. Having voltage in y-axis and
time in x-axis. We also wish if the cell balancing circuit can be connected and
disconnected to the batteries to show the usefulness of it.

b.) To implement a SOC estimation and Fuzzy Temperature Control for charging and discharging
integrated to the system.
 For the soc estimation, please show a graph for the 20 batteries for their
respective soc; having SOC in the y-axis and time in x-axis.
 For the fuzzy temperature control. If possible, you can show here only 1
graph for the whole battery pack as one. Having temperature in the y-
axis and time in the x-axis. A temperature range of 10 to 30 will be more
preferred.
c.) To determine the runtime of the batteries while being discharge by the load when a solar panel
is connected to the system.
 The system should work with or without solar panel or the solar panel can be
connected and disconnected.
