Detailed Description
The following description of the embodiments with reference to the accompanying drawings will provide further detailed description of the embodiments of the present invention, such as the mutual positions and connection relationships between the related parts, the functions and working principles of the parts, and the operation and use methods, to help those skilled in the art to more completely, accurately and deeply understand the concept and technical solutions of the present invention.
Examples
The management assembly of parallel smart batteries as shown in figure 1,
the direct current charger and the direct current discharger are connected to the buses at two ends of the DC/DC converter.
The bus is externally connected with a 220V alternating current power supply. The 220V alternating current passes through the AD/DC converter to form an internal bus voltage, and the bus simultaneously provides electric energy for the DC/DC converter and the direct current charger. The DC/DC converter will generate a DC bus voltage of 220V. The DC charger outputs 12V voltage to charge the storage battery.
When alternating current loses power, the voltage at the end of the storage battery is boosted and output through the DC/DC converter to form internal bus voltage, and the assembly can realize uninterrupted switching to battery power supply.
The DC/DC converter is connected with the DC/DC charger through a circuit.
The AD/DC converter, the DC/DC converter direct current charger and the direct current discharger are all controlled by a CPU, and the CPU controls the starting and the closing of the direct current charger and the direct current discharger.
The CPU is connected with a temperature sensor which is used for detecting the temperature of the storage battery. When the temperature of the storage battery is too high, the CPU receives a signal of the too high temperature.
The CPU central processing unit is also provided with an RS485 interface and an RS232 interface, and the RS485 interface and the RS232 interface are used for connecting a computer and a display screen. The control of the components may be implemented by a computer. Temperature information, operation information, and the like of the components are displayed through the display screen.
