ST STEVAL-L99615C User manual

Introduction
The STEVAL-L99615C is an evaluation kit composed of an expansion board containing the L9961 IC for battery pack monitoring
solutions, and the NUCLEO-G071RB STM32 Nucleo-64 development board, aiming to demonstrate the performance and the
ease of integration with STMicroelectronics technology for BMS applications.
The kit exploits the characteristics of the L9961, able to monitor up to five Li-Ion battery cells in series configuration,
communicating with the STM32G071RB microcontroller, through the I²C interface.
The expansion board has been specifically developed to be stacked on the NUCLEO-G071RB development board through the
ST morpho connectors, and embeds a power connector able to connect it to a 5-cell battery pack, or alternatively to an external
power supply to emulate the battery pack.
A software package containing a dedicated firmware program for the STM32G071RB microcontroller and a GUI for the PC, has
been released to permit users to benefit from the demonstration, looking at the major significant characteristics described by
BMS application: cell voltage and stack voltage monitoring, stack current monitoring, temperature conversion via external NTC,
OV, and UV thresholds management, etc..

1.1 Overview
The STEVAL-L99615C features:
• measurement of cell voltages (3 to 5 cells), with over/undervoltage detection
• measurement of stack voltage, with over/undervoltage detection and plausibility check vs. sum of cells
• measurement of battery pack temperature through an external NTC (emulated by an on-board trimmer)
with over/undertemperature detection
• measurement of battery current, with Coulomb counting, overcurrent, and short-circuit in discharge
protection
• battery cell balancing supporting up to 70 mA per cell
• dual configurable HS/LS pre-driver for pack relay management
• pack fuse management
• high hot plug robustness
1.2 System architecture
The STEVAL-L99615C evaluation kit consists of two subsystems:
• the NUCLEO-G071RB STM32 Nucleo-64 development board embedding the STM32G071RBT6
• the expansion board embedding the L9961 that monitors the battery pack and physically protects the
battery-packed application, contributing also to maintain the expected voltages
Figure 2. NUCLEO-G071RB - L9961 expansion board
1.2.1 NUCLEO-G071RB development board
The NUCLEO-G071RB STM32 Nucleo-64 development board is based on the high-performance Arm Cortex®-
M0+ 32-bit RISC core operating at up to 64 MHz frequency, with 128 KB flash memory and 16 KB SRAM.
The ST morpho headers allow expanding the functionality of the STM32 Nucleo open development platform with
a wide choice of specific shields.
The STM32 Nucleo-64 boards do not require any separate probe as they integrate the ST-LINK/V2-1 debugger/
programmer. They embed comprehensive, free STM32 software libraries and examples available with the
STM32CubeG0 MCU package.

1.2.2 Expansion board
The expansion board hosts the L9961 BMS device, a complete battery pack monitoring, balancing, and protection
system for Li-Ion and Li-Polymer cells in 3, 4, or 5 series configurations. The device uses a high precision
ADC to provide cell voltage, stack voltage, and temperature conversion via external NTC. Voltage monitoring
functions are cyclically performed with a programmable loop time. Stack current is also monitored via a high
accuracy CSA, continuously running and also performing Coulomb counting. Cell balancing is available and can
be simultaneously activated on all cells. IC configuration and information exchange for SOC/SOH estimation are
performed via the I²C peripheral.
The IC also integrates a dual pre-driver programmable in both HS/LS configurations for driving pack relays. The
L9961 also implements battery pack fuse protection to prevent fire and explosion hazards. A 3.3 V regulator with
a high current capability is available for supplying a pack controller and other external circuitry in both standby
and normal operation modes. The IC protects the battery pack against over/undervoltage conditions and monitors
for over/undertemperature. It also features protection against overcurrent (both directions) and short-circuit in
discharge events. Safety relevant configurations can be stored in the internal NVM to avoid reprogramming the
device at each wake-up.

1.2.3 Power supply section
In case a real battery is not available, it is possible to use the battery simulator embedded on the L9961 demo
board by installing a J5 jumper and by feeding the L9961 demo board through the CN2 connector (B+ and B-).

1.2.4 Pack relays stage
The L9961 uses a dual pre-driver stage to manage the external Charge (CHG) and Discharge (DCHG)
switches. The pre-driver stage can be configured as high-side or low-side by programming the CHG_HS_LS
and DCHG_HS_LS field.
To set the DCHG MOSFET to high-side operation, remove the J13 and J14 jumpers and install a jumper in J15
and J16 position 1-2 or for low-side operation, remove the J19 and J20 jumpers and install a jumper in position
2-3. To set the CHG MOSFET to high-side operation, install a jumper in J17 and J18 position 1-2 or for low-side
operation, install a jumper in position 2-3.

Under certain conditions classified as permanent failures, the L9961 can be programmed to activate the FUSE
pre-driver. An external NMOS can be driven to blow up a fuse connected in series to the battery pack positive
terminal.

1.2.6 L9961 demo board connectors
The CN1 is a 10-pin IDC style connector used to route sense signals from the remote 5-cell battery board to the
L9961 demo board. The connector contains the Kelvin connections for C0 through C5, the current sense resistors
differential voltage, and the NTC voltage, which can be used to route an external NTC and shunt resistor.
If the external Rshunt is used, R11 should be uninstalled and replaced with the new one.
If the external NTC is used, R12 should be removed. Once it has been removed, the user can connect the
external resistor between the NTC and OD pins. It is important to polarize the NTC with an external pull-up
resistor biased to VREG. For further details regarding the application circuit, please refer to the "Application
Information" section in the L9961 datasheet.

3.2 How to run the application demo
To run the application demo, in voltage and NTC temperature acquisition mode, follow the procedure below:
Step 1. Verify that the setting of the STEVAL-L99615C jumpers respects the configuration reported in Table 4.

JP3 NUCLEO STM32 VDD current measurement Open
JP2 NUCLEO STM32 5 V jumper selection 1-2: 5 V from STLINK
CN4 NUCLEO STM32 SWD interface Closed
Step 2. After installing the GUI from the STSW-L99615C SW package to the laptop, and confirming that the kit
Nucleo board is programmed with the firmware binary contained in the same SW package (refer to the
UM3141), connect the STEVAL-L99615C to the laptop through the USB cable.
Note: In the case of NUCLEO programming, refer to the STM32CubeProgrammer user manual for firmware
uploading.

UM3151 - Rev 1 page 11/30

Step 3. Connect the power supply terminals to the B+ and B- pins of the battery pack connector (CN2), and
power on the appliance (suggested setting 7.5 V, 1 A as test rating).
Figure 11. How to connect the power terminals to the battery
UM3151
How to run the application demo
UM3151 - Rev 1 page 12/30

Step 4. Launch the GUI on the laptop and verify the COM used by the evaluation board is recognized by laptop
Operative System (WINDOWS in the described case) device manager. If recognized, the GUI releases
a message on the left part of the bottom side of its template, referring to the connected COM number
used.

Step 5. Clicking on the GUI tab "Register Load", upload the example CSV file "Voltage Acquistion Init -
5Cell+VB+NTC.csv" also embedded in the SW package file, and then click the "Play" button. This
operation presets an instruction set that permits the GUI to demonstrate the acquisitions of voltage
cells and battery pack, and also NTC acquisition. After completing the register loading operation, press
OK to begin voltage acquisition.

Figure 16. Register Load: csv commands loaded
Step 6. Then, opening the "L9961 Demo" tab and setting the Periodic Timer (for example to 250 ms), it is
possible to observe the direct acquisition of the voltages on each cell: in fact, applying 7.5 V to the
CN2 connector (on VB+ and VB+ pins), the five resistive dividers integrated in the STEVAL-L99615C
expansion board and emulating the battery pack circuit, return 1.5 V for each cell.
