Hardware: electric car charging interface industry standards
It has been reported that the charging stations in China there is no uniform standard interface, and the introduction of charging interface standard is expected to change this situation. With the National Grid and China Southern Power Grid has developed a large-scale construction of the National Electric Vehicle Charging Station load and stack pilot scheme, the electric vehicle charging station construction has entered the fast lane. Power plants of trucks needed for the construction of a direct interface to hardware and other equipment necessary to complete in less than half an hour to reach 75% charge, this component is to achieve universal charging stations to promote more critical. With the construction of the swing this year, charging stations, market demand for the CC interface would be more urgent.
Domestic production of interface charges related accessories, said the chief engineer, charging businesses related to construction of the station have already started preparatory work, while charging stations for electric vehicles matching the DC, AC interface devices already in the production process test, and now the rules, and found that the rules introduced earlier, for China to achieve universal charging station, the better.
2010, the national network planning processes in the construction of a loading station the most attractive, while the electric vehicle charging interface standard will be a step forward. According to the National Standards Board sources, the standard by the National Automotive Standardization Technical Committee centralized.
Tianjin Qingyuan Electric Vehicle Co., Ltd. was, in addition to the national grid, no BYD, Chery and other car companies to participate. All this time, China is not standard uniform of the docking station interface, and the introduction of charging interface standard is expected to change this situation. Participates in drafting rules of the relevant sources are charging interface to affect the formulation of international standards, especially in the DC charging interface and logic control for the protection of safety, are made by our country first.
China electric car charging interface standard discussion document has been submitted for consideration, the State Committee of Standards. In accordance with the Committee's request, is now entering phase of testing equipment and data accumulation, as soon the end of June this year, is expected to be approved.
Executives said that because electric vehicles in China has just begun, the manufacturers launch or prototype or concept car, no charging stations, taking into account the future needs of the charger interface. Only a few years ago, manufacturers mobile phones, as their own way each production of the phones with a different charger, and even part of the production of different models with different cell phone chargers, mobile phone users to replace the end result should be the new shopping magazine. The automaker proposals must participate in the development of industry standards as soon as possible, do not repeat the mistakes of the mobile phone charger.
Currently manufacturers electric car market has not yet formed, the charge is not a unified interface, does not look bad if the road electric vehicles to reach 10% -20%, Feeding problems will be exposed. In addition, for the car charger is not only a unified interface to resolve, but also by type of battery capacity, size, charge mode, charging current, voltage and rational allocation.
The relevant parties involved in the development standards that the standards are reviewed perfect, but the overall technical architecture will be no major changes. There are several manufacturers now offer the exchange of interface products load. DC port cargo companies such as amphetamine precision connectors Novo has arranged like pieces of production.
