Abstract

The invention discloses a storage battery pack connection circuit and an intelligent storage battery pack. The storage battery pack connection circuit comprises a plurality of battery units, wherein one pole of each battery unit is electrically connected with one output end of a voltage reduction and stabilizing circuit through a first switch, the other pole of each battery unit is electrically connected with the other output end of the voltage reduction and stabilizing circuit through a second switch, and the input end of the voltage reduction and stabilizing circuit is electrically connected with a charging input circuit. Further, controllable switches are adopted for at least the first switches and the second switches and are controlled by a first control unit. One pole of each battery unit is electrically connected with one output end of the voltage reduction and stabilizing circuit through a third switch and the first switch which are connected in series. The intelligent storage battery pack comprises the storage battery pack connection circuit. According to the storage battery pack connection circuit and the intelligent storage battery pack, the rated charging voltage of the storage battery pack can be changed, reverse charging of the storage battery pack for a charging device is avoided, and the storage battery pack can work in the floating charge state.

Description

technical field

[0001] The invention relates to a battery pack, in particular to a novel battery pack connection circuit and an intelligent battery pack. Background technique

[0002] The potential crisis of fossil energy has made the use of renewable energy more and more important to all mankind. The construction of renewable energy systems and facilities such as wind power plants and photovoltaic power plants often includes battery packs. For wind power plants and photovoltaic power plants, energy storage is the most important means of adjusting active power. High-power, large-capacity energy storage systems can stabilize the volatility and intermittency of wind power and photovoltaic power. The safety and normal operating efficiency of battery packs are crucial to the operation of wind and photovoltaic power plants.

[0003] Most of the energy storage of battery packs in current wind power and photovoltaic power generation systems adopts the following working principles...
