比亚迪2015年就量产800V,但充电设施跟不上,看比亚迪怎么解决2023-12-26 11:13·哔哔车事在新能源汽车发展初期,行业普遍面临三无困境:一无充电技术,二无充电基础设施,三无充电标准。为破解这些发展难题,比亚迪率先实现充电技术从0到1的突破,在车端和桩端,皆自研了家用和公共领域的交、直流充电技术,为国标交、直流充电标准提供了参考范本,也成为首批中国电动汽车充电标准起草单位。比亚迪的五大首创技术解决充电难题,让中国新能源汽车充电技术有了“根”。充电一直是新能源用户最关注的痛点,也是比亚迪技术创新和研发投入的重点领域,只为让用户享受充电体验的跃升。用户痛点1:早期电动车体验差,充电效率低比亚迪全球首创800V高电压平台和升压充电技术在新能源汽车普及初期,为了突破动力、续航、充电等方面的技术上限,给用户创造更极致的电动车体验,电动车高压化的技术突破势在必行。比亚迪率先在2015年实现突破,全球首创乘用车800V高电压平台,搭载在秦EV(2015款)、唐DM(2015款)等车型上。该技术可实现百公里加速快至4秒级,纯电续航里程可达450km、快充功率提升至60kW,全方面升维用户体验。比亚迪800V高电压平台超前行业2-3代,当时,市面上的乘用车都是低电压,只有比亚迪是高电压。时至今日,行业竞相进入800V高电压平台赛道。高压车型虽然大幅提升电动车充电功率,但在当时,国内95%都是500V以下的低压桩,与高压车型充电不兼容,影响了充电效率。为解决这个难题,比亚迪全球首创升压充电技术,彻底实现车桩兼容,全面适配所有直流充电桩。用户痛点2:大部分快充桩还是充得不够快比亚迪全球首创乘用车双枪超充技术,让公共快充桩秒变超充桩目前而言,电流超过300A的公共超充桩仅有2%,快充桩普及广,超充桩极稀缺,与其让用户去争夺极少数的超充桩,不如充分利用现有超过百万台的公共快充桩资源。为此,比亚迪推出更符合我国充电国情的升流方案,全球首创乘用车双枪超充技术,让公共快充桩秒变超充桩,短时多补能,处处能超充。以腾势N7为例,双枪超充最大功率可达230kW,公共快充桩上实现15分钟充电350公里。既要持续的快,还要安全的快。因为升流技术对电池热管理考验更严苛,比亚迪全球首创复合直冷技术,通过电池上下两面均铺直冷板的设计,以及2套冷媒独立控制系统,进行了补偿式流道设计,电池冷却面积提升100%,换热能力提升85%以上,为用户超充安全保驾护航。用户痛点3:北方冬季充电效率大打折扣比亚迪全球首创全场景智能脉冲自加热技术,北方极寒也能快充北方冬季极寒,充电效率慢。比亚迪首创全场景智能脉冲自加热技术,在行业内首次实现了极低温下冷车快充。在-30℃极寒条件下,以腾势N7为例,全场景智能脉冲自加热技术让电池加热速率较传统方案提升230%,电池满充时间降低30%,北方用户冬天也能享受到快充体验。不仅在充电时能自加热,在驻车和行车状态下,都能智能启动自加热技术,保障极低温整车性能。构建更符合当下国情的充电技术体系,不断升级用户的全场景充电体验凭借20年的技术积淀和深厚功底,比亚迪持续创新和研发投入,构建更符合当下国情的充电技术体系,不止于快,不断升级用户的全场景充电体验。
