Abstract

The invention provides an intelligent communication type battery charge and discharge optimization control system. The system is composed of battery control panels and at least one battery unit control module set connected with the battery control panels, wherein the battery unit control module set is composed of a plurality of battery unit control modules which are electrically connected with the battery control panels in parallel. Each battery control panel comprises a signal processing module a, a signal processing module b, a voltage adjusting circuit module, a communication module, a power bus and a data bus which are all connected with the corresponding control module. The method for implementing the system includes the steps that when the current input voltage is larger than a preset norminal voltage, the multiple battery control panels are connected with the power buses in parallel so that charging can be performed; otherwise, the multiple battery unit control modules are connected with the power buses in series, and the multiple battery unit control modules are controlled to perform discharging. Due to the intelligent communication type battery charge and discharge optimization control system, safety and stability of battery packs can be improved, the charging speed of the battery packs is increased, and the service life of the battery packs is prolonged as a whole.

Description

technical field

[0001] The invention relates to the field of battery charge and discharge control, in particular to an intelligent communication type battery charge and discharge optimization control system. Background technique

[0002] At present, lead-acid batteries (VRLA) or lithium batteries or iron-lithium batteries are widely used in industrial energy storage equipment and power batteries (including but not limited to electric vehicles or the Other areas where the power battery is the driving force). In some small independent photovoltaic power generation systems, the performance of the battery energy storage system is particularly important for the efficiency of solar energy and the stability of the entire photovoltaic system. However, due to the characteristics of the battery itself and the technical limitations of battery charge and discharge management, the use of traditional charge and discharge methods (such as constant current, constant voltage, etc.) will cau...
