【摘要】：自电池被发明200多年以来,电池系统一直是采用固定串并联的系统架构,即很多小容量的单体电池根据负载的要求固定串并联成一个电池系统。然而,由于生产和工况引入的单体电池差异性,这种固定串并联的系统架构给电池系统带来了很多应用上问题,如SOC和SOH的测不准问题、电池充放电均衡问题、电池的梯次利用问题及可靠性和安全性问题等。借鉴软件定义的理念和具体实现,软件定义可重构电池系统可以从根本上解决电池单体差异性与固定串并联成组方式之间的不匹配问题,进而解决了一系列电池应用问题。本文将重点讨论基于可重构电池网络的软件定义可重构电池系统原理及其应用。
[Abstract]:Since the invention of the battery for more than 200 years, the battery system has been using a fixed series-parallel system architecture, that is, many small capacity of single-cell battery according to the requirements of the load fixed series-parallel into a battery system. However, due to the difference of single cell introduced in production and operating conditions, this fixed series-parallel system architecture has brought many problems in the application of battery system, such as SOC and SOH uncertainty problem, battery charge and discharge balance problem. Battery trapezoid utilization problem and reliability and safety problems and so on. Referring to the concept and implementation of software definition, the software definition reconfigurable battery system can fundamentally solve the mismatch between the battery unit difference and the fixed series-parallel group mode, and then solve a series of battery application problems. This paper focuses on the principle and application of software definition of reconfigurable battery system based on reconfigurable battery network.
