Product Parameters

High-end BMS

waterproof, shock-proof and anti-extrusion BMS

Daly BMS is famous for waterproof, shock-proof and anti-extrusion. It adopts fully enclosed one-piece ABS injection molding, which provides a solution for the industry problem of BMS sealing.

Premium Micro Controller Unit

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).
