The difference between automobile high-voltage wiring harness and electric vehicle charging cable: In electric vehicles, electric vehicle high-voltage cables are used to connect the charging port and the battery, inside the battery, and between the battery and the engine. Components, as well as battery storage devices, as a vehicle for power transmission inside the vehicle.
The difference between automotive high-voltage cables and charging cables is divided into 10 aspects: different laying, different heat resistance, different EMI requirements, different protection measures, different physical performance requirements, different size requirements, different color requirements, and number of cable cores Different, different international standards, etc. Protective measures: The internal environment of the car is complex and harsh, and there are necessary protective measures around the high-voltage cable of the car; the charging cable has no protective measures and can withstand various shocks and ultraviolet radiation. Physical performance requirements: Automobile high-voltage cables need to meet the wear-resistant requirements of automobiles; charging cables should meet the anti-extrusion requirements of mobile cables. Chemical resistance: Automotive high-voltage cables need to withstand various liquids that can be contacted on the car; charging cables need to withstand various liquids from the living environment outside the car. Size requirements: The automotive high-voltage cable is limited by space and has strict size requirements. The smaller the size, the better; the charging cable has no size limit, and can be made thicker and larger. Color requirements: Internationally, the color of automobile high-voltage cables is orange; however, there is no requirement for the color of charging cables. Among them, OMG charging cable features for products with more specifications and models that meet the requirements, For more information about on EV cable of new energy vehicle and electric vehicle charging cable products, please browse the OMG official website and contact us : https ://www.omgevcable.com/ddqcqddl/97.html |

各地区电缆讨论话题：电力电缆的未来是什么？众多公司正在应对行业的转型......随着时间的推移逐一证实，新能源的发展，发展电动汽车是对减少能源过度消耗的举措之一。当然，电动汽车的发展，充电电缆以及充电领域是对电动汽车未来发展举措。简单的说，有电动汽车就有充电电缆以及充电连接设备，如传统燃油车对于资源汽油来说，同样重要，因为这是使得带来驱动动力。当然，在未来发展当中，不断经过技术的研发，EV充电电缆和EV线缆对产品有更多的完善。
对于不同规格型号的电动汽车充电电缆和车辆内部使用的电力电缆，选择质量好的电缆很重要，是对整车的接线配件设备有效地运行。
EV线缆是电传的主要组成部分,主要分为充电桩/站用线缆材料和车内高压线缆材料。由于高压高电流和使用环境苛刻,对线缆材料提出很高的安全规范和使用要求。
汽车用高压电缆的组成：相同高质量于EV电缆，主要用材料由导体铜线等高分子结构组成，对性能要求十分苛刻，所以对高压电缆的选择质量很重要。 ------------------------------------------------------------ What is the future of power cables in all regions cable discussion topics? Numerous companies are dealing with the transformation of the industry ...... As time goes by, the development of new energy sources, the development of electric vehicles is one of the initiatives to reduce excessive energy consumption. Of course, the development of electric vehicles, charging cables and the charging field is to the future development of electric vehicles initiatives. Simply put, there are electric vehicles have charging cables as well as charging connection equipment, such as traditional fuel cars for resources gasoline, equally important, because this is made to bring driving power. Of course, in the future development, constantly after the development of technology, EV charging cable and EV cable to the product has more perfect. For different specification models of EV charging cables and power cables used inside the vehicle, it is important to choose good quality cables, which are wiring accessories equipment for the whole vehicle to run effectively. EV cable is the main component of electric transmission, mainly divided into cable material for charging post/station and high voltage cable material for vehicle interior. Due to the high voltage and high current and harsh use environment, the cable materials put forward high safety specifications and use requirements. The composition of high-voltage cables for automobiles: the same high quality as EV cables, the main materials used are composed of conductors such as copper wire and other polymer structures, which are very demanding in terms of performance, so it is important to choose the quality of high-voltage cables. 更多产品结构咨询请留意OMG产品页面： https ://www.omgevcable.com/ddqcqddl/97.html |

Nowadays, for electric vehicles, increasing the cruising range to make long-range electric vehicles is the main development path. When the cost of batteries drops and the combined range reaches 500-600 kilometers, the main contradiction of electric vehicles changes from range anxiety to charging anxiety. Improving the charging power of electric vehicles mainly includes several core elements. The following is the way to analyze the reasons: First: increase the current. If we keep the other components the same and choose the path to increase the current, the main limitation is the heat loss due to the high current, which can make a big difference in the overall design. High currents in a circuit create high heat losses, as the resistance of all components (connectors, cables, electrical connections to batteries, bus bars, etc.) inevitably heats up. If the battery overheats during charging, these heat losses need to be taken into account when designing and sizing conductive elements to avoid problems such as overloading, overheating, or controlled derating of the charging current. Second: increase the voltage. Since the increase of the above current is limited, the current limiting current is generally defined as 500A, and the achievable power is around 200kW (Tesla designed more than 600A at 400V as an attempt), increasing the voltage to switch the 400V system to 800V becomes an option. This is a systematic improvement of all electrical components. The core switchgear and other parts have changed. At current costs, these modules developed to the 800V specification are relatively expensive. Taking the main inverter as an example, the cost of the core SiC module is about 4 times that of the original IGBT module. Let's take a closer look at some of the issues that need to be considered in a path that can be reached either way. Since several methods have the same requirements for the cell, we list the cell problem at the end, focusing on the electrical connection and thermal management inside. |
