Function of SP22S003A/B Software BMS

Function	Configuration	Function	Configuration
Number of Strings Supported	6S~22S	485 Communication(Isolated)	Not Supported
Continuous Current	40A~100A	UART Port(Isolated)	Not Supported
Number of NTCs	1 Built-in, 2 External	CAN Communication	Not Supported
Balance Function	Passive Balance	232 Communication	Not Supported
UART(Non-isolated)	Standard Option	Heating Function	Not Supported
Switch Function	Optional	Module of Bluetooth	Standard Option
Charging Current Limit	Not Supported	Battery Packs in Series	Optional
Battery Packs in Parallel	Not Supported	Secondary Protection	Not Supported
History Storage	Not Supported	LCD Dispaly	Not Supported
Pre-discharge Function	Not Supported	LED Indicator Port	Not Supported
Buzzer	Not Supported	GPS Port	Not Supported

Note:

The UART interface (non-isolated) does not support communication with chargers or loads.
The battery pack can be used in series, but the total number of strings after series is required to be less than or equal to 32.
6 ~ 22 battery cells are protected in series, and the number of battery strings is automatically identified.

Communication Functions

SP22S003 smart bms supports two communication methods, Bluetooth and uart.

The connection method is: after installing the special driver for our communication box on the computer side, insert the USB end of the communication box into the USB port of the computer, and connect the other end to the corresponding interface of the protective board that has been connected to the battery. Open the host computer, click the communication port settings, select the CMO port corresponding to the communication box, other options

do not move, after confirmation, click Start, you can read the protected data. If you need to change the parameters of the protection plate, you must first click Read Parameters on the Parameters page before changing the parameters.
