Product Parameters

Intelligent communication, human-computer interaction

The Daly smart BMS has three communication functions of UART, RS485 and CAN, which can be connected to the PC SOFT, display screen, and mobile APP, to intelligently manage the lithium battery. If you have customized requirements of communication protocols such as mainstream inverters and Chinese tower protocol, we will provide high-quality customized services.



Daly has developed a mobile phone APP. After the Bluetooth is plunged into the BMS, the BMS can connect to mobile phone APP, which can monitor the battery data the relevant parameters in real time, such as battery voltage, total voltage, temperature, power, alarm information, charging Discharge switch, etc.


Daly “Smart” BMS

Only by realizing high-precision detection and high-sensitivity response to voltage and current, the BMS can achieve great protection for lithium batteries. Daly standard BMS adopts IC solution, with high-precision acquisition chip, sensitive circuit detection and independently written operation program, to achieve voltage accuracy within ±0.025V and short-circuit protection of 250~500us to ensure the efficient operation of the battery and easily handle complex solutions.

For main controlling chip, its flash capacity up to 256/512K. It has the advantages of chip integrated timer, CAN, ADC, SPI, I2C, USB, URAT and other peripheral functions, low power consumption, sleep shutdown and standby modes.

In Daly, we have 2 DAC with 12-bit and 1us conversion time (up to 16 input channels)
