“或许这项技术并不能从根本上杜绝充电自燃事故,但至少让所有人看到了新能源企业为安全所做的努力。”
电动汽车起火事故频频发生,为了防范这一重大安全事故,车企和电池厂商都做了很多工作。但是据“E车汇”了解,多数自燃起火事故都是在充电过程中发生的,如果能够有效规避充电过程中起火,电动汽车的安全事故将大幅降低。
而防范充电过程中起火,一方面要求车辆有足够安全的设计,另一方面则要求充电桩有安全的防护措施。
中国电动充电基础设施促进联盟的最新数据显示,截止到今年5月份,特来电自营+非自营的充电桩数量为128365台,是国内充电桩运营数量最多的充电桩运营商。行业头部企业的动向总是能很快引起注意。
“E车汇”注意到,特来电母公司特锐德在5月13日发布公告称,子公司特来电发布了面向新能源车安全的充电网两层防护技术,同时来自工信部和多位车企的专家组对这一技术进行了鉴定,认定该技术成果使得充电过程及汽车安全隐患做到可监视、可预警、可控制、可追溯。
作为运营充电桩最多的企业,特来电的这一技术如果实现大规模应用,这对于新能源汽车行业来讲,都是有极大促进作用的。
主动保护充电安全
历史数据显示,80%的新能源汽车自燃事故是在充电中或充满电后一小时,这种自燃事故能够通过充电网的主动防护有效解决。
据特来电大数据云平台统计,在2018年特来电的5300万笔订单中,特来电防护体系共防范了32万次的不安全充电,安全防护比达0.6%,避免烧车事故16起,降低事故发生率达65%;而2019年1月-3月,充电安全两层防护技术也已经预防了多起重大事故。
此次特来电发布的充电网主动防护技术就是基于过去的充电数据来打造的。
过去,电动汽车充电是由车载的电池管理系统(BMS系统)主导的,充电过程中,BMS系统在监测动力电池的电压、电流、温度等情况的同时,对充电管理系统发出指令。然后充电管理系统响应BMS系统的需求,来给电池充电。
而特来电的充电网主动防护技术则是在BMS系统之外,另加了一个柔性智能充电管理系统(CMS系统)。通过CMS系统,充电桩也能够主导充电过程,这就相当于是给充电过程又增加了一道保险,让充电桩能主动保护充电过程的安全。
充电桩企业所做的努力
“E车汇”在查询之前的充电起火事故调查报告后发现了一个共性特点,那就是充电系统运营单位、数据监控平台、整车企业对监控到的数据未给予重视,在充电过程中监控数据出现异常时,没有及时采取措施,最终酿成了祸患。
不过近两年随着新能源汽车大规模发展,充电桩企业也都意识到了这点。包括星星充电、国家电网在内的运营商,都为充电桩设置了一些安全保护措施,如短路保护、过流保护、欠压保护、过压保护、防拔保护、急停保护、漏电保护、防雷保护、阻燃保护等等。有了这些保护措施,在正常充电的情况下,发生安全事故的概率大大降低了。
与这些充电桩运营商相比,特来电此次发布的这项技术显得更为先进,它不仅有以上这些保护措施,还能够基于历史充电数据做出预判,甚至能够基于充电过程的数据给出动力电池维修保养的建议。
实际上,电动汽车在充电过程中,电池状况、电压、电流、充电曲线是有着非常巨大数据的,把这一数据收集起来,不仅能够建立起充电数据模型防止充电安全事故,如果特来电把这些数据共享给整车厂或是动力电池厂商,对于提高电动汽车的整体安全性也是有极大促进作用的。
在电动汽车安全方面,电池厂商通过新材料新技术的应用,能够提高安全水平;整车厂通过优化车辆设计,与电池厂商联动,也能够提高安全水平。而特来电此举,则代表着新能源汽车产业链上的其他参与者也在主动出击,解决充电安全问题。
新能源汽车要发展,只有迈过安全这道槛,才能够真正实现健康良性的发展。这就需要大家共同维护行业的安全,一起推动新能源事业的发展。
