Two 100KΩ resistors also form a voltage divider for the microcontroller to read the battery voltage through pin A0''s ADC channel, and I''m planning to add an example firmware which reads and
It uses detection voltage and current modules to detect the lithium battery of electric vehicles in real time. At the same time, it uses an OLED display module to display the status data of the
Lithium ion battery charger and discharger for checking the capacity. Analog circuits for charging and discharging, ADC, LCD, I2C, and STM32F103C8T6 (ARM) blue mini board were used for

Hooray, it’s fully charged! Our first step is designing an STM32 board with a battery charger, a battery connector, and an ADC connection to read the battery’s voltage. Most lithium batteries today have a charge voltage of 4.2V, which I like to think Douglas Adams would appreciate, but most STM32s have a maximum voltage of 3.6V.
In this paper, a master-slave power battery management system based on STM32 microcontroller is designed. It adopts modular and master-slave design, and realizes the communication between host and slave by CAN bus. In this paper, the 270 V battery pack is designed, that is, the battery pack is composed of 76S12P (76 series 12 parallel) 18650 cells.
Using the onboard USB to UART adapter we can program the board simply by connecting the board to the PC with a USB connection. STM32 microcontrollers always come preloaded with a program called bootloader residing in a special memory area called system memory. The bootloader makes it possible to program the STM32 through UART, SPI, or I2C.
We can program the STM32 in different ways. The most popular method is through SWD pins employing an external ST-Link. However, programming using UART is obviously more convenient. Using the onboard USB to UART adapter we can program the board simply by connecting the board to the PC with a USB connection.
