Description

Light stores up integrated intelligent control system based on dynamic voltage matches Technical Field The utility model relates to the technical field of energy storage systems, in particular to an optical storage integrated intelligent control system based on dynamic voltage matching. Background With the development of renewable energy technology, photovoltaic power generation systems are increasingly used. However, the conventional photovoltaic energy storage system has the problems of low energy utilization rate, short battery life, poor expansibility and the like. For example, the energy loss caused by mismatch of the photovoltaic panel output voltage and the battery charging demand, the influence of lack of intelligent charge and discharge management on the battery life, and the like. In addition, the existing system has insufficient flexibility when facing different load demands, and is difficult to meet the demands of diversified application scenes. Therefore, there is a need for an energy storage and discharge control system that can achieve high efficiency management, extend battery life, and provide flexible scalability and economy. Disclosure of utility model Aiming at the defects existing in the prior art, the utility model aims to provide an optical storage integrated intelligent control system based on dynamic voltage matching, which realizes efficient utilization of photovoltaic energy, optimization of battery life and flexible expansion of the system through dynamic voltage matching and intelligent control, is suitable for off-grid and micro-grid scenes, and has economy and reliability. In order to achieve the purpose, the intelligent light storage integrated control system based on dynamic voltage matching is achieved through the following technical scheme that the intelligent light storage integrated control system based on dynamic voltage matching comprises a plurality of photovoltaic plates, the photovoltaic plates are connected with contactors through DC-DC voltage reduction modules, the contactors are connected through diodes, the contactors are connected with a battery pack and a voltage acquisition module, the voltage acquisition modules are connected in parallel and connected with a control system, and the control system is connected with an illuminance acquisition module. Preferably, a plurality of photovoltaic panels are provided. Preferably, the control system adopts a PLC or a singlechip. Preferably, the voltage acquisition module monitors the battery state in real time, and the voltage acquisition module acquires 0-55V in the range of 0-5V analog input. Preferably, the battery pack adopts three 12V batteries connected in series to form 36V nominal voltage, and each battery pack is connected in parallel. Preferably, the photovoltaic panel is further connected to a plurality of MPPT controllers. Preferably, the battery pack adopts an aviation plug, and an RFID tag for automatically identifying the capacity and the health state of the system is built in the battery pack. The beneficial effects of the utility model are as follows: 1. high efficiency energy management and utilization Dynamic voltage matching charging-photovoltaic panel outputs 40V voltage, while charging voltage requirement of 12V battery pack (3 blocks are connected in series with 36V nominal voltage) is about 43.2V (assuming that single 12V battery charging voltage is 14.4V). The system can realize MPPT (maximum power point tracking) optimization through voltage acquisition and PLC/singlechip control, ensures high-efficiency matching of photovoltaic panel output and battery charging requirements, and reduces energy loss. The sectional charge and discharge control is to adopt parallel units (36V) during charge and switch to serial connection (for example, the serial connection of 3 units is 108V) during discharge, so that the discharge voltage is increased to reduce the line current and the transmission loss (P=I 2R /), and the sectional charge and discharge control is especially suitable for long-distance or high-power loads. 2. Battery life and safety optimization And the intelligent charging protection is that the voltage acquisition module monitors the state of the battery in real time, prevents overcharge (automatic switching to a discharging mode after full charge), avoids damage of the battery due to overvoltage or overheat, and prolongs the service life of the lead-acid/lithium battery. And the battery state (such as SOC estimation) is judged by combining the voltage/current double parameters, so that the control precision is improved. The heat dissipation design of the battery needs to be enhanced when the high-current serial discharge is performed, avoiding the influence of temperature rise. And in the design of balanced charge and discharge, when a plurality of cells are serially connected for discharge, the PLC can rotate the sequence of the cells, so that the long-term overload of individual cells is
