Therefore the pack current, cell temperature, and each cell voltage should be monitored timely in case of some unusual situations. The battery pack must be protected against all these situations. Good measurement accuracy is always required, especially the cell voltage, pack current, and cell temperature.
This paper describes a stackable battery monitoring and management integrated circuit for EVs. Owing to the number of cells in the series, the amount of data transmitted by the BMS is significant. The integration of digital control and registers in the BMIC is necessary for the efficient execution of each function.
The first op-amp O1 measures the voltage of the 2 nd cell by calculating the difference between 2 nd cell terminal and 1 st cell terminal that is (8-4). Similarly the Op-amp O2 and O3 measures the 3 rd and 4 th cell voltage respectively. We have not used an op-amp for the 1 st cell since it could be measured directly.
A structurally complete battery monitoring chip design is presented in Ref., which supports seven-cell series battery stack monitoring and has two additional temperature monitoring channels. A 12-bit SAR ADC was designed to achieve a measured accuracy of ±7 mV.
You can use any resistor value but they all should be of the same value, except for the resistors R13 and R14. These two resistors form a potential divider to measure the pack voltage of the battery so that we can compare it with the sum of measured cell voltages.
