Abstract

The invention discloses an intelligent charging management module of a photovoltaic power supply, which includes a solar photovoltaic battery pack, an energy storage battery and an electricity load. The solar photovoltaic battery pack and the energy storage battery are connected by a charging control circuit. The energy storage battery and the electricity load are connected by a discharging control circuit. An intelligent charging and discharging management module is arranged between the charging control circuit and the discharging control circuit. The intelligent charging and discharging management module includes a central processing unit, a charging efficiency monitoring circuit and a power consumption efficiency monitoring circuit. The charging time monitoring circuit and the power consumption efficiency monitoring circuit are connected with the serial input terminals of the central processing unit. A first control switch for controlling the on-off of the charging control circuit and a second control switch for controlling the on-off of the discharging control circuit are respectively arranged at the corresponding output terminals of the central processing unit. Through the scheme, the charging status of the battery can be monitored in real time, the battery can be prevented from being damaged by over-charging or over-discharging, and the service life of the battery can beprolonged.

Description

technical field [0001] The invention relates to the field of photovoltaic power sources, in particular to an intelligent charging management module and management method for photovoltaic power sources. Background technique [0002] Energy is an important material basis for economic and social development and improvement of people's living standards, and energy issues are a crucial issue for a country. With the rapid development of science and technology and the global economy, the demand for energy is also increasing. Since the world oil crisis in the 1970s, people have truly realized that the reserves of fossil fuels are limited and the energy crisis is imminent. From a global perspective, the proven disposable traditional energy reserves will be exhausted in the near future. The prominent energy problems are not only manifested in the lack of conventional energy, but more importantly, the development and utilization of fossil energy has a negative impact on the ecological...
