该文件包含锂离子电池模型参数估计和仿真。 1）估计。SLX锂离子电池包含一个等温的单电池模型，具有1-RC等效电路 2）单细胞模拟（SSCL锂离子电池1RC.SLX）。该模型利用在等效电路元件内布置为查找表的估计实例的参数，模拟单电池在简单脉冲充放电循环下的电热响应。 3）电池组，抽象版本（SSCLILIUMUBATYYY1CELL。SLX）。 4）电池组，详细版本（SSCLILIUMUBATTYYY80CCELL，SLX）。(This document contains parameter estimation and Simulation of lithium-ion battery models. 1) estimate. SLX lithium-ion battery contains an isothermal single cell model with 1-RC equivalent circuit. 2) single cell simulation (SSCL lithium ion battery 1RC.SLX). The model simulates the electrothermal response of a single cell under a simple pulse charge discharge cycle, using the parameters of an estimated example of the lookup table in the equivalent circuit element. 3) battery pack, abstract Version (SSCLILIUMUBATYYY1CELL). SLX). 4) battery pack, detailed version (SSCLILIUMUBATTYYY80CCELL, SLX).)

说明：  如题，关于HHT变换的三种方法，是目前最全的。(The three methods of HHT transformation are the most complete at present.)
