Electric vehicles rely on electricity to achieve vehicle driving, so after using electric vehicles for a period of time, the battery needs to be charged without electricity. Many consumers are very confused about this charging problem, because unlike traditional fuel vehicles, electric vehicles can drive without oil and refueling, However, it must be charged for a period of time before driving, which is why consumers don't know much about electric vehicles. When it comes to electric vehicle charging, they have to mention electric vehicle charging cables. Today I'll introduce the requirements of electric vehicle charging cables.
Its function requires that the electric vehicle charging cable is the carrier connecting the electric vehicle and the charging pile, and its basic function is to transmit electric energy. However, with the development of charging technology, in order to better complete the charging process, electric vehicles and charging piles need to communicate and automatically control when necessary. Therefore, the charging process puts forward higher requirements for the charging cable (EV cable). The charging cable not only needs the high-voltage cable (EV HV cable) to have the function of power transmission, but also needs to transfer the status and information of the vehicle and power battery to the charging pile for real-time interaction, and control the charging action under necessary conditions, so as to complete the charging process safely and reliably.
At present, the safety of electric vehicles has become the focus of the industry. In the charging and discharging process of electric vehicles, due to long time, high current intensity and high frequency of cable use, its safety should be highly valued. On the basis of ensuring good insulation performance, electric vehicle charging cable shall have high heat resistance and aging resistance. At the same time, it shall have good low smoke and flame retardant characteristics during combustion, so as to minimize loss and injury.

New energy electric vehicles must be familiar to everyone. How much do you know about the wires and cables inside the vehicle? As for the thickness of vehicle high-voltage cable, in fact, the principle of household cable used is the same as that of other electric field. For example, comparing two kinds of high-voltage cables (divided into thickness and thickness) of two vehicles, it is concluded that the quality of high-voltage harness of "thin wire" is lower than that of “thick” high-voltage harness.
Of course, these are two kinds of high-voltage harnesses, which have different functions and cannot be directly compared. There are many specifications and models of vehicle high-voltage cables, such as 3mm ² -70mm ². For example, for electric vehicles, under nearly 400V high voltage, the high-voltage line used for 85KW motors is very different from the high-voltage line used for 6.6kw chargers - "thickness", that is, the difference in the cross-sectional area of copper wire, which is also obvious. Therefore, the vehicle high-voltage harness is assembled on different parts according to the power demand.
The high-voltage harness is connected to the spare parts on the vehicle, including drive motor, air conditioning system, on-board battery, etc. These applicable materials are also common materials according to the matching requirements of devices, such as 125 ℃ XLPE and 180 ℃ silica gel, which have high and low temperature resistance and tear resistance. The cable material is thermosetting material, and the wires and cables are soft and smooth, Cables of different specifications and models are made of shielded or unshielded materials.

什么是新能源汽车和能源的融合?"?新能源汽车融汇新能源、新材料和互联网、大数据、人工智能等多种变革性技术,推动汽车从单纯交通工具向移动智能终端、储能单元和数字空间转变,带动能源、交通、信息通信基础设施改造升级,促进能源消费结构优化、交通体系和城市运行智能化水平提升,对建设清洁美丽世界、构建人类命运共同体具有重要意义。"此句意味着对新能源电动汽车战略意义和未来场景描绘的非常清晰。政府对新能源汽车的产业规划和未来格局的判断真的是高屋建瓴。 有个大背景,新能源车虽然是零排放,但由于国内是为主,能源不是零排放,所以在?"30?·?60?双碳目标?"?提出后,由为代表的可再生能源将逐步被光伏风电为代表的不可再生能源替代,风电和太阳能发电等新能源的跨越式发展,给储能发展带来了新机遇。 关于新能源汽车与能源的融合方式,《新能源汽车产业发展规划(2021?—?2035?年)》也做了相对明确的解释:要促进新能源汽车与可再生能源高效协同,鼓励?"?光储充放?"(分布式光伏发电—储能系统—充放电)多功能综合一体站建设。 第一类是固定式?"?光储充放?",也就是大家最常见的固定式微网,利用光伏发电,将电量存储在储能电池中,储能电池将电量供给充电桩使用,通过光储充系统,太阳能被转移到汽车的动力电池中,供车辆行驶使用,新能源车从能源到车辆都变成了零排放。 第二类是移动式微网,曾毓群一直在提,宁德时代三大发展方向的第一个是?"?移动式储能替代?",新能源汽车搭载?60?度以上的电池包,在满足放电功能的情况下,就是一个典型的?"?移动式储能?"?工具。所谓汽车与能源的融合包括充放两个概念,清洁能源充电到车辆,车辆作为储能工具放电,我们日常所提的?V2G(Vehicle-to-Grid)仅仅是放电形式的一种。 那么汽车与能源的融合是不是很遥远?无论是产业还是资本,大家对?"?光储充放?"?的观点是:目前?"?光储充放?"?的发展阶段就像十年前的新能源汽车,考虑到产业的融合速度和技术、成本发展加快,光储充放的成熟度和普及度将远远超过新能源汽车,也就是在?3-5?年后,光储充放将有希望在城市或者乡村得到较多的应用推广。 所以,今年以来,光储充放一直在二级市场最关注的领域,在新能源车水涨船高的情况下,该领域仍然是估值洼地,中国新能源汽车虽然起步较早,但在光储充放建设和应用方面,着实不如欧美国家,由于电价原因,国内的光储充放发展较慢,始终没有跑出一家像特斯拉一样的能源企业。 特斯拉为何是一家能源公司?众所周知,特斯拉是汽车与能源的结合全球最好的公司,没有之一,本质上,特斯拉不仅是一家汽车公司,也是一家能源公司。如果说在自动驾驶领域,特斯拉领先其它车企半个身位,那么在能源领域,特斯拉领先其它企业一个身位。 提到特斯拉能源,大家能想到的一般是?Supercharger(超级充电桩),国内每家企业都在做超充桩,但这不是特斯拉能源的全部。有媒体报道,充电仅仅是汽车与能源结合的一个环节。要了解有关电动汽车充电桩电缆和充电电缆的更多信息,请访问OMG的官方网站:https://www.omgevcable.com/ 以下为特斯拉光储充能源分布概念介绍 特斯拉的?"?光储充放?"?系统一共包括三个产品,第一个?"?光?"?环节产品,即特斯拉的?Solar Panels(太阳能面板),在这个?"?大太阳能?"?概念里,大家只需要看隆基股份的市值,便能感受到市场的无限空间;第二个是?"?储?"?环节产品,即?Powerwall?家用电池组——固定式的家用?"?充电宝?",容量不高,但足以满足家用,过去特斯拉没有电池生产能力,Powerwall?家用电池组一直是用的松下的电芯,现在特斯拉也有了电芯制造能力。从更大的范畴来说,特斯拉的汽车动力电池可以看做是?"?储?"?环节的另一个产品,汽车动力电池扮演的是移动式的家用?"?充电宝?";第三个是?"?充?"?环节的?Supercharger(超级充电桩),这个产品大家非常熟悉。 ? 特斯拉的光储充也分为两个应用场景,第一个场景是公共领域光储充系统,即?"?光储充?"?一体化充电站,太阳能屋顶系统发电后,将电能储存在?Powerwall?电池中,最终可供部分纯电动车日常充电。第二个场景是私人家庭的光储充系统,即?"?家庭式光储充微网?",太阳能发电,Powerwall?和新能源车电池包作为储能工具,满足家庭的用电需求。 ? 最后,中国的?"?光储充放?"?还有多远?中国过去的?"?光储充?"?发展很慢,主要是因为没有良好的外部环境,一是中国以为主,上网电价非常便宜,二是中国的城市家庭没有条件安装?"?光储充?"?基础设施。 欧美国家在这个领域的优势非常明显,从家用电价成本看,中国每度电大概是?0.08-0.1?美元,美国每度电大概是?0.15?美元,而欧洲国家基本都在?0.2?美元以上,欧美国家居住分散且面积大,安装?"?光储充?"?基础设施也有先天优势。 尽管国内没有太好的基础,但政府在近两年一直出台政策推动?"?光储充?"?的发展,建设了多座光储充一体化充电站,江苏、、上海、北京、山东等地的光储充充电桩都已投入运营,但由于成本和运营等问题,多为?"?示范运营?",未进行大面积推广。 当资本市场认为?"?光储充?"?将因为市场化问题延缓发展时,国家发布了?"?双碳目标?",这就意味着国内必须加大清洁能源的使用比例。 转自网络,仅供分享交流,不代表本论坛立场,如涉及版权等问题,请告知,我们将及时处理 |
