The utility model operation principle
Adopt I
2C communication bus (P0.0 of C8051F005H and P0.1 mouth), do to isolate mutually between the assembly with the TLP113 optocoupler, communication realizes the intercommunication between the parameters such as electric current, voltage, when large current charge, need discharge in time to eliminate the voltage that intensifies at rechargeable battery two ends, and during discharge, each charhing unit must stop charging, discharge control signal and charhing unit cut-off signals adopt the I/O port control (P1.1 of C8051F005H, P3.0 and P3.1 mouth) of host scm, guarantee to open, disconnect synchronism and real-time between the charhing unit.
Receive for the first time the communication information (may be the information that self sends) from the charhing unit back that powers on, outwards send self address code and current sampling data every 10ms.As clash I
2C can adjust sending order automatically according to the priority of each charhing unit information.Because it is all inequality that each charhing unit sends the priority of information, so they can send automatically according to a certain order.Each charhing unit calculates the charhing unit sum of parallel operation, and obtains the mean value of all sample rate currents after self sends information 10ms, the controlling unit of notice charhing unit.Because I
2C communication capacity and extremely low error rate at a high speed, all charhing units can both send current sampling data and allow each charhing unit receive within the 10ms.Charhing unit detects when self breaking down, and should in time cut off output, and withdraw from communication.
The utility model advantage
1, applied widely.Adopt the charhing unit of band communication function, can realize the charged in parallel between the charhing unit.
2, peripheral circuit is simple, and current sharing is good.Because charhing unit has adopted communication to make the hardware flow equalizing circuit.
3, high reliability.The circuit elements device is few, does not have complicated components and parts.
