For a long time Chinese electric car charging port industry, " all of the dry " chaos coming to an end . About electric vehicle charging interfaces and communications protocols recently approved the release of four national standards , and will become effective March 1, 2012 implementation .
According Hengding wheel hub bearing unit noted , these four criteria are " electric vehicle conductive charging connection device - Part 1 : General requirements" , " electric vehicle conductive charging system - Part 2 connector : AC Charging Interface" "electric vehicle conductive charging connecting devices - Part 3: DC Charging Interface " communication protocol between the conduction of electric vehicles -board charger and battery management system" . " These standards are set by China's National Energy Administration , Ministry of Industry and Information Technology , Electricity Council and other agencies steam Research Center jointly drafted .
Since China has no uniform standards in the electric vehicle charging interface, the enterprise "staking " " all of the dry ", leading to the same company to sell electric vehicles in different parts of the country and the standards to be performed separately for each local docking . For example, in Beijing to adopt a standard national grid , while in Shenzhen, China Southern Power Grid to adopt the standard . This chaotic situation is not conducive to long-term development of China's electric vehicle industry.
Ministry of Equipment Industry official said that the National Standards Committee for coordination and support of the tripartite Ministry of Industry , Energy Board , Electricity Council and other partner to launch these four criteria , the unification of the relevant market , to fill the gap , for Chinese electric vehicle industry, far-reaching impact .
The four national standards promulgated , will provide important technical and standards support infrastructure for electric vehicles , to improve China's new energy vehicle standards, promote new energy vehicle demonstration pilot , and promote the coordinated development of new energy cars of significance .
Of course, we standardized the operation of charging facilities may want to solve some problems , the first question and there is a problem with the car , and the car is more focused on protocol issues with charging interface and back . Of course, charging facilities that we need a system of product quality and the whole society . Many of our large-scale construction of charging stations later , we need a unified standard problems, and finally run our maintenance charging facilities also need this standard . So now we have to engage in a standardized charging infrastructure operations , mainly to solve problems in four areas just talked about .
Our country has its own set of standards developed very strict rules and regulations, we generally related to the establishment of Standardization Technical Committee to be responsible. Currently electric car itself is responsible for standards by the National Automotive Standardization Technical Committee set up under the electric cars of the Technical Committee to be responsible for . Charging the energy field facility Standardization Committee responsible sector , the problem related to the interaction , for example, the problem of interface problems , communication protocol is determined jointly by the two technical committees.
According Hengding wheel hub bearing unit is understood that the electric vehicle charging facilities Standardization Technical Committee was set up in 2010 , from the auto companies , charging facilities manufacturing companies also have a battery companies and power companies , it should be said that both have the production line also has research units , also Yes, there are experimental institute in the manufacturing sector , and from all aspects , we probably constitute nearly 50 members of our technical committee . Usually one of our standard , the final technical checks by the Technical Committee to finalize the .
