Detailed Description

As shown in fig. 1, a centralized charger for multiple types of storage batteries comprises a charger and a control box; the system comprises a master controller, a charger and a plurality of sub-control boxes; the master controller is simultaneously connected with a plurality of sub-control boxes; the multiple sub-control boxes are connected with a charger, and the charger is connected with a power box;

after receiving the charging parameters, the sub-control boxes automatically set the charging time and automatically adjust the charging current value and the voltage value to charge the storage battery, and after the preset time is reached or the storage battery is charged to the set value, the storage battery is closed to charge;

in the charging process, the sub-control boxes monitor the storage battery in real time and perform linkage control, and the storage battery stops charging when reaching the warning value.

In the embodiment, the master controller is a control box with a control panel and a PC port, the control box mainly comprises a main control panel, a touch control panel and some external switches,

the external can change the charging parameters through the control panel, the main control board transmits the parameters to the control box, the control box feeds the charging data back to the main control board in the charging process, and the next step (such as record storage, charging continuation, charging termination, abnormal alarm and the like) is executed after the judgment of the main control board

The charger introduces electricity into the equipment from a power box, the equipment reaches the highest voltage capable of directly charging the storage battery after passing through a transformer and rectification filtering, and then the highest voltage passes through a busbar to a sub-control box, the sub-control box modulates the voltage and the current, and then the storage battery is charged through an electric wire

The sub-control box has three functions, the first is that the charger changes the transmitted power into the voltage and current needed by the storage battery, the second is the on-off function between the motor and the storage battery, the third is the feedback of the storage battery state (such as feeding back the parameters of current, voltage, time, temperature and the like to the master controller, the sub-control box is also provided with a master control board, and the parameters needed by charging are obtained through pulse width modulation

The multiple sub-control boxes are formed by the charger and the master controller and can be provided with a plurality of sub-control boxes, but each storage battery needs to be supplied with power by a single sub-control box during charging, so that storage batteries of different brands, different specifications and different capacities can be guaranteed, and the storage batteries can be charged simultaneously.

The working principle of the centralized charger in the embodiment is as follows:

the charger is connected with a 380V power supply of the power box, the 380V power supply is distributed to a primary coil through a power panel (coil switching is carried out according to different output voltages and power), a main transformer outputs the voltage after changing the voltage through rectifying to 18VDC, parameters such as power, current and the like can be monitored during output, the parameters are connected to an inlet of a sub-control box through a bus bar, the sub-control box outputs the required voltage and current through pulse width modulation to 13-16V, and then the winding type charging wire is used for completing charging of the storage battery.

The master controller can operate and set charging parameters through a computer, select a charging mode (a common charging mode, an activation charging mode, a trickle charging mode and a three-section charging mode) according to the requirements of the storage battery, and receive the real-time state fed back to the storage battery by the sub-control boxes. And a data storage function.

The master controller controls the sub-control boxes through serial port communication;

after the sub-control boxes receive the charging parameters, the charging time is automatically set, the charging current value and the voltage value are automatically adjusted to charge the storage battery, and the storage battery is stopped to be charged when the preset time is reached or the storage battery is charged to the set value

In the charging process, the storage battery can be monitored in real time, and linkage control can be performed, for example, when the charging temperature reaches a set value, the storage battery is cooled, and when the charging temperature reaches a warning value, charging is stopped; or when harmful gas is detected, the indoor exhaust fan is automatically turned on.

The sub-control box has the functions of identifying the voltage of the battery, detecting the reverse connection of the polarity, detecting the short circuit, protecting the disconnection of the charging, automatically cutting off the power supply when the battery is fully charged, protecting the overcharge and the like.

The centralized charger of the embodiment realizes that a plurality of devices are changed into one, and reduces the purchase cost. Meanwhile, the labor intensity of workers is reduced, the field mobile equipment, the setting time, the current, the voltage parameters and other work are centralized on the master controller, and the storage battery can be charged after the setting on the master controller is finished. In addition, the charging data can be fed back to the storage battery in the charging process, the safety state can be monitored, and the storage battery with abnormal data is subjected to emergency power-off treatment.
