欧盟委员会2011年9月8日于布鲁塞尔发布的一项倡议,要求从2015年开始在所有新汽车和轻型车辆上安装称为eCall的紧急呼叫系统,这给电池在恶劣环境下的操作性能设立了新的标准。本文描述了传统标准电池设计要做出怎样的改进,才能满足eCall及类似系统在极限温度下运行的要求。1车载紧急呼叫系统的用途和运作欧洲的eCall,以及世界其他地方类似的倡议,如北美的OnStar和bCall(故障呼叫)系统,即将在未来几年内在世界许多地区使用,用以减少交通事故造成的死亡人数并减轻伤害。所有这些系统的基本运作都是类似的:拿eCall来说,就是将一个拥有
An EU initiative launched in Brussels on September 8, 2011, called for the installation of an emergency call system called eCall on all new cars and light vehicles starting in 2015, which set the operational performance of the battery in harsh environments New standard This article describes the improvements that traditional standard battery designs have to make in order to meet the requirements for operating eCalls and similar systems at extreme temperatures. Purpose and Operation of On-Board Emergency Call Systems European eCall and similar initiatives from other parts of the world, such as the OnStar and bCall systems in North America, are expected to be used in many regions of the world in the coming years to reduce traffic accidents The number of deaths and reduce the injury. The basic operation of all of these systems is similar: for eCall,
