The disclosure provides intelligent vehicle battery charging for high capacity batteries. A system and method for intelligent battery charging management to improve battery life and charging efficiency of high capacity batteries that may not be deeply discharged on a regular basis may learn driving habits automatically and/or with user input and select an ending state-of-charge (SOC) to limit battery charging to less than maximum capacity based on current and/or anticipated ambient temperature and battery health of life (HOL). An expected vehicle travel distance before the next charge may be learned or determined based on vehicle or user inputs. An ending SOC based on battery temperature, a delta SOC to meet propulsive energy for the expected travel distance, cycling effect (depth of discharge) on battery HOL for a given delta SOC, and/or battery working efficiency may be used to control charging of the vehicle battery.
本公开提供“用于高容量电池的智能车辆电池充电”。一种用于智能电池充电管理以改善可能不会定期深度放电的高容量电池的电池寿命和充电效率的系统和方法可以自动地和/或利用用户输入来学习驾驶习惯并基于当前和/或预期的环境温度和电池寿命健康状态(HOL)选择最终荷电状态(SOC)以将电池充电限制到小于最大容量。可以基于车辆或用户输入来学习或确定下一次充电之前的预期车辆行驶距离。基于电池温度、针对所述预期行驶距离满足推进能量的ΔSOC、对于给定ΔSOC的对电池HOL的循环效应(放电深度)和/或电池工作效率的最终SOC可以用于控制对所述车辆电池的充电。
