Use and requirements of new energy vehicles

The new energy vehicle charging cable is mainly used to connect the new energy vehicle and the charging pile, which is exposed for a long time,  It needs to be resistant to moisture, low temperature and weather; In addition, it is necessary to bend, drag and move frequently during use, which is easy to cause wear, scratch, rolling and other damages,  Therefore, the charging cable is required to have good physical and mechanical properties, and higher requirements are required for the weight, flexibility, flexibility, mechanical properties and corrosion resistance of the cable.

Requirements for charging wires of new energy electric vehicles

1. It is recommended to charge every day, so that the battery is in a shallow cycle state, and the battery life will be extended;    2. In the process of use, the charging time and frequency should be accurately controlled according to the actual situation. Over-charge, over-discharge and under-charge will shorten the battery life;    3. Avoid the plug heating during charging. If the heating time is too long, it will cause the plug short circuit or poor contact, and damage the charger and battery. Therefore, in case of any of the above conditions, remove the oxide or replace the connector in time;    4. Be sure to follow the instructions on the protection of the charger in the manual, and try to protect the charger to prevent vibration and turbulence. In addition, keep the charger ventilated when charging, otherwise it will not only affect the life of the charger, but also affect the charging state and cause damage to the battery;    5. Perform a full discharge of the battery on a regular basis, and then fully charge the battery. A regular deep discharge of the battery is also conducive to "activating" the battery, which can slightly increase the capacity of the battery,   Introduction to electric vehicle charging line: functional requirements: electric vehicle charging cable is the carrier connecting electric vehicle and 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, it is necessary to communicate between the electric vehicle and the charging pile, and carry out automatic control when necessary,   Therefore, the charging process puts forward higher requirements for the charging cable. The charging cable not only needs to have the function of power transmission, but also needs to transmit 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,   Safety requirements At present, the safety of electric vehicles has become the focus of the industry. The charging and discharging process of electric vehicles should be highly valued for its long time, high current intensity and high frequency of cable use. On the basis of ensuring good insulation performance, the electric vehicle charging cable shall have high heat resistance and aging resistance, and at the same time, it shall have good low-smoke flame-retardant characteristics during combustion to ensure the minimum loss and damage.
