Product Introduction
ACEY-SP04S034 is a software protection board scheme specially designed for 3~4 strings of lithium battery packs. The product adopts architecture of front-end acquisition chip + MCU, and some parameters can be flexibly adjusted through the host computer according to customer needs.
Features
3-4Series cell protection in series.
The cells are intelligently balanced, and the balanced turn-on voltage and differential pressure can be flexibly adjusted through the host computer. Optional charge equalization or static equalization.
Integrated hardware protection functions such as overvoltage, undervoltage, overcurrent, and short circuit.
A variety of working modes, the protection board can disguise and go to sleep when it is static to achieve the purpose of reducing power consumption.
Comes with two communication ports, which can read voltage, current,SOC, temperature, protection status and other data.
UART (TTLlevel) can be externally connected to Bluetooth, computers and non-battery powered devices, isolatedRS485Can communicate with controllers, chargers, etc. device communication.
