Week 7 State of charge estimation

CONCLUSION

• This system does the estimation by the coulomb counting equation mentioned above.
• Advantage of the coulomb counting method is its simplicity and low computational cost.
• Temperature and current from the battery are given as inputs.
• Current signal is given to a gain block and temperature is given to capacity since it varies according to temperature.
• These inputs are given for integration where the current will be integrated with respect to time.
• This output is given to another block where it is divided by capacity.
• Hence the SOC is estimated.
• The 3 test cases from the harness dashboard were successfully simulated and discussed, along with the BMS's coulomb counting for SOC estimation.
