New energy electric vehicle charging method

Due to the serious pollution on a global scale, all countries attach great importance to the development of the environmental protection industry, and the wire and cable industry is believed to have a long-term development with this opportunity. With the gradual implementation of projects such as coal reform, the demand for wire and cable industry is constantly increasing.

For electric vehicles, the charging device must meet the requirements of safety, convenience, economic cost, efficiency, etc. Currently, the most common charging methods on the market include charging methods such as charging pile charging stations, replacing batteries, and wireless. charging method.

Conventional charging is also slow charging: the car is usually charged in the traditional way of constant voltage and constant current. The charging current is about 15A. If the battery is 120A·h, the charging should last at least 8 hours. Generally, the charging pile will be connected after work at night, and it will be full the next morning. This charging method is a relatively common electric vehicle charging mode at present, because the cost is low and the work is stable. Generally, the charging power of the civilian charging device is 5 to 10 kW, and the three-phase four-wire 380V power supply or the one-way 220V power supply is used. The low charging current is good for battery life, but the disadvantage is that the charging rate is slow.

Fast charging method: Generally, the battery is charged in a short time with a high charging current of 150 to 400A. Fast charging and charging methods require better batteries and charging piles. Not all electric vehicles can be charged quickly. It needs to be fast charged according to the manufacturer's requirements. The main purpose of fast charging is to fully charge the electric vehicle in a short time. This charging mode generally has a charging power of more than 30 kW, and is powered by a three-phase four-wire 380V. Although the charging speed is increased, because the battery heat is rapidly increased during the rapid charging process, and the internal chemical reaction is vigorously performed in the battery, the life of the battery is affected to some extent, so that the later use cost of the electric vehicle is greatly increased.

Omega has advanced production equipment and strong technical force, and has received guidance and support from many scientific research units and relevant experts. The product quality has reached the domestic advanced level and has obtained the product quality inspection certificate. The products are sold at home and abroad. By the majority of users alike. Ogilvy's electric vehicle charging cable has obtained UL, German TüV, China CQC certification, China Dekai certification, and Omega is also the China Quality Certification Center (CQC) cable specification for electric vehicle conduction charging system (CQC1103-2014, Drafting unit of CQC1104-2014, CQC1105-2014).

Ogilvy's cables are closely related to the safety of electric vehicles. Omega's high-voltage lines and charging lines are one of the core components of the new energy vehicle safety system. Electric vehicle safety includes three aspects, the safety of power batteries, the safety of electric vehicles, and the safety of charging infrastructure. High-voltage lines and charging lines play an important role in the safety of the power battery and the safety of the charging infrastructure.
