The working principle of the system is explained as follows:
as shown in fig. 2, the system is connected to the battery pack. The leading-out terminal of the relay J1 is connected with the anode of the storage battery pack; the leading-out terminal of the relay J2 is connected with a neutral point of the storage battery pack, namely the position of a pole of the storage battery pack with the positive voltage of 1/2 total voltage of the storage battery pack; the leading-out terminal of the relay J3 is connected with the negative electrode of the storage battery; the current transformer L1 is arranged at the position from the storage battery pack to the positive bus and is used for measuring the current from the bus to the system resistor; the current mutual inductor L2 is installed at the positive outlet of the storage battery pack to measure the current from the positive to the system resistance, and the current mutual inductor 3 is installed at the negative outlet of the storage battery pack to measure the current from the negative to the system resistance.
In operation, the reliability of the battery connection is checked every other time indicated by a time shift switch.
Firstly, the connection reliability of the storage battery pack and a bus is detected, the relay J1 and the relay J3 are controlled to be closed, two ends of a series circuit of a resistor R1 and a resistor R2 are respectively put into the positive pole and the negative pole of the storage battery pack, and then the current I from the storage battery pack to the positive pole of the bus is measured through a current transformer L1. In the float state, the bus voltage is slightly higher than the battery pack voltage, so the current passing through the resistor R1 and the resistor R2 is mainly supplied by the bus, so if I is larger than zero, the CPU judges that the battery pack and the bus are reliably connected, and if I is 0, the CPU judges that the battery pack and the bus are open-circuited and failed, which means that the current passing through the resistor R1 and the resistor R2 is supplied by the battery pack.
Then, the internal connection reliability of the battery pack is detected. After the reliability of the connection between the storage battery pack and the bus is detected, the relay J3 is opened, and the relay J2 is closed, so that the resistor R1 is thrown into the positive half group of the storage battery pack. Meanwhile, the current transformer L2 collects the current I1 at the positive electrode outlet of the storage battery, if I1 is larger than 0, a loop circuit of the positive half group of the storage battery is connected reliably, and if I1 is equal to 0, an open circuit fault exists in the positive half group of the storage battery. And after the judgment is finished, the relay J1 is opened, the relay J3 is closed, the resistor R2 is put into the negative half group of the storage battery, and meanwhile, the current I2 of the cathode outlet of the storage battery is measured through the current transformer L2.
In the faults, when any fault exists, the CPU controls the alarm indicator lamp to flash, controls the alarm buzzer to alarm, controls the alarm node to act, and controls the uplink communication module to upload alarm information to the upper computer.
After the detection is finished, the device enters timing again, and when the timing time reaches the time indicated by the timing gear switch, the next detection is carried out, and the steps are repeated.
