Module, synchronous clearing device and the MCU, the communication module are connected with the sampling unit by signal communication.
Further, the sampling unit quantity is more than or equal to 2.
Further, the signal communication communicates for CAN communication or UART.
Synchronized sampling battery management system, acquisition method are specific as follows：
Main control unit is communicated by modes such as CAN, UART with sampling unit, in the communication starting stage, main control
Unit sends a frame synchronization warning order to sampling unit in advance, after sampling unit receives synchronous warning order, immediately enters
The sampling preparation stage simultaneously informs main control unit, while resets synchronizer trigger.After synchronizer trigger is cleared, it will detect automatically
First edge of signal of communication（Rising edge or trailing edge）After trigger sync level.
All sampling units synchronously detect the edge on order wire on signal communication bus node, and trigger synchronous detection electricity
It is flat.
After synchronizer trigger triggers synchronous warning order, all sampling units can receive and detect synchronized sampling electricity
It is flat.After all sampling units detect synchronized sampling level, internal analog-digital converter starts simultaneously at work and to opposite
The module answered synchronizes sampling, total voltage for synchronization of each sampling unit detects at this time voltage, current data, list
Bulk voltage, loop current information.Data letter of the main control unit by all sampling unit acquisitions on communication bus collector node
Breath, master control at this time according to these can be more accurate, more efficient completion SOC estimations, internal resistance estimation, the management such as strategy.
A kind of PCBA function detection devices provided by the invention and monitoring method, have the advantages that.
By hardware trigger realize the monomer voltage of battery pack, total voltage, loop current synchronous acquisition, it is of low cost,
Control is simple, greatly improves accuracy, the reliability of BMS systems, while solves the crosstalk of high-low pressure harness, production assembling
Danger reduces main control unit and system, the risk for endangering personnel safety, endangering battery core is damaged due to high pressure seals in, is conducive to
The maintainability in later stage.
