Electric Vehicle Charging Cables – Hybird Resources
Electric Vehicle Charging Cable is a recently emerged low voltage electrical equipment cable and wires.Its technical requirements are different from traditional cable and wires. Nowadays, Electric Vehicle Technology has become the focus technology for auto industry to deal with the environment pollution and relief energy crises.Each country and major car manufacturers in the world have invested heavily into the research and development of electric vehicles.
While the electric vehicle technology becoming more and more mature and wildly applied,the construction of its relevant charging facilities has becoming more and more important. Electric Vehicle Charger Cable is a basic part of the charging facilities,and has significant influence to the whole charging progress.However, electric vehicle charging cable is a new type of cable, its application requirements are different to traditional cables.
While the electric vehicle technology developing,these cables technical requirements becomes clearly gradually.
1)Electric Vehicle Charging Cable application ambient requirements
There are three type of connections for EV charger cables.First,EV charging cable permanently connected with electric vehicle,but it can be plugged and disconnected with electrical network.Second,EV Charger Cable permanent connected with electrical network while it can be plugged and disconnected with electric vehicle.Third,EV charging cable to both electric vehicle and electrical network can be plugged and disconnected.No matter which one applied,the following ambient requirements should be encountered.
EV Charger Cable is usually used outdoor,exposure to UV in long term.Therefore,it will encounter many harsh nature environments,including large day and night temperature difference,sunlight exposure,weathering, humidity, acid rain, freezing and sea water, etc.,These harsh environments will seriously affect the EV charging cable service life and performance,even reduce its reliability and safety,causing property damage and personal injury.
While charging the electric vehicle with EV charging cable,due to its flexibility,it is inevitable that there will be bending, twisting, drag and even stretching and other phenomena,These actions are easily to cause mechanical damage to the charging cable;In the mean time,EV Charging cable may immersed in acid and alkali solution,which will affect the material performance and damage the charging cable.Due to its relatively harsh operational environment,EV charging cable requires higher performance for its flexibility,torsion resistance,mechanical property and corrosion resistance.
Electric vehicle charger cable is connected between electric vehicle and charging pile, and its basic function is to transmit electric power.However, with the development of charging technology,in order to better the charging process,electric vehicles need to communicate with the charging pile,and sometime may need automatic control.
Therefore,the charging process for the electric vehicle requires higher performance of the charging cable.The EV charging cable will transmit electrical power,and convey the vehicle and battery status and relevant information to the charging pile in real time.And if needed,EV will automatically control the charging process to finish the charging safely and reliably.
Recently,the safety of the electric vehicle has become the focus of the industry.And the safety for the EV Charging and discharging process should be highly concerned,due to its long time,big current,and high frequency of using.
EV Charging Cable should assure good insulation performance,and higher heat and aging resistance performance.This Cable also should have better low smoke and flame retardant performance to minimum damage and injury while fire happened.
