By default, charger a, charger B and charger C may all charge any bin battery. The basic principles of scheduling are: and scheduling charging according to the time sequence of the bin batteries and the current state of the charger. The sequence of battery placement and the state judgment of the charger are obtained by the cabinet control module software according to the real-time data judgment of the battery bin and the charger. The specific method comprises the following steps:
the method for judging the battery insertion comprises the following steps: the program of the cabinet control module 130 sends a heartbeat query message to the battery compartment at a fixed time of 100ms, and when the battery is placed, the battery replies current data of the battery after receiving the heartbeat query command. After the cabinet control module 130 successfully reads the battery information, it may mark that the battery is placed in the bin, and further record the current time of the battery entering the bin.
The method for judging the state of the charger comprises the following steps: the program of the cabinet control module 130 sends a heartbeat inquiry message to the charger at regular time of 200ms, and under normal conditions, the charger returns to the current real-time state after receiving the heartbeat message of the cabinet control module 130. The real-time status information includes a charging status, a charging current, a charging voltage, and the like. After receiving the real-time data, the cabinet control module 130 further performs state analysis to obtain a corresponding result. Then, states of the charger working, the charger idle, the charger abnormal and the like are marked. And when the message is sent abnormally, or the cabinet continuously sends three heartbeats without receiving the message reply of the charger, or the data of the message reply of the charger is abnormal, marking that the charger is abnormal.
Under the condition that the charger is not damaged, when the situation that the battery is placed in the bin 1 (the battery bin 1) is detected, whether the charger A is in an idle state (not in a charging working state) or not is judged at the moment, and if the charger A is in the idle state, the charger A is scheduled to charge the battery in the bin 1.
And if the charger A is in the working running state, judging whether the charger B is in the idle state, and if the charger B is in the idle state, scheduling the charger B to charge the battery in the bin 1.
And if the charger B is in the working state, judging whether the charger C is in the idle state, and if the charger C is in the idle state, scheduling the charger C to charge the battery in the bin 1.
When the charger A is damaged and the battery is placed in the bin 1, judging whether the charger B is in an idle state, and if the charger B is in the idle state, scheduling the charger B to charge the battery in the bin 1. And if the charger is in the working operation state, judging the state of the charger C. If it is in the idle state, charger C is scheduled to charge the battery in bay 1.
And similarly, when the charger B and the charger C are damaged, judging the states of other normally working chargers.
When only one normal charger is left when the two chargers are damaged, the normally working charger can schedule charging according to the time sequence of battery placement. If charger A and charger B are damaged, charger C is normal. The battery is put into bin 2 (battery bin 2), bin 4 (battery bin 4), bin 3 (battery bin 3), and bin 1 (battery bin 1) in order, and then charger C will charge bin 2 earlier, and after the battery in bin 2 was full of, the battery in the other bin 4, bin 3, bin 1 was charged in proper order again, and it is full of to all bin batteries.
