Problems solved by technology
However, a single photovoltaic air conditioner is often only equipped with a single battery pack. The energy storage capacity of the battery pack is limited, and it cannot effectively use the electric energy generated by large-area photovoltaic panels, resulting in energy waste and reduced energy utilization.
In addition, the battery pack may be overcharged or overdischarged during use, which may lead to safety issues such as fire and combustion in severe cases.

Description
technical field [0001] The invention relates to the technical field of solar power generation, in particular to a photovoltaic air conditioner, a battery management system and a control method thereof. Background technique [0002] Photovoltaic air conditioners are air conditioners powered by solar energy. Generally, photovoltaic air conditioners are often equipped with batteries to store electric energy. However, a single photovoltaic air conditioner is often only equipped with a single battery pack. The energy storage capacity of the battery pack is limited, and it cannot effectively utilize the electric energy generated by large-area photovoltaic panels, resulting in energy waste and reduced energy utilization. Moreover, the battery pack may be overcharged or overdischarged during use, which may lead to safety problems such as fire and combustion in severe cases. Contents of the invention [0003] In view of the small capacity of the battery pack of the above-mentioned...
