DC Charging Sockets For Electrical Vehicle


Electric Vehicle Connector:  A device that, by insertion into an electric vehicle inlet, establishes an electrical connection to the electric vehicle for the purpose of power transfer and information exchange. This device is part of the electric vehicle coupler.

Electric Vehicle Coupler: A mating electric vehicle inlet and electric vehicle connector set.
(A) Polarization: The electric vehicle coupler shall be polarized unless part of a listed electric vehicle charging system or an electric vehicle supply equipment system
(B) Noninterchangeability: The electric vehicle coupler shall have a configuration that is noninterchangeable with wiring devices in other electrical systems. Nongrounding-type electric vehicle couplers shall not be interchangeable with grounding-type electric vehicle couplers.
(C) Construction and Installation: The electric vehicle coupler shall be constructed and installed so as to guard against inadvertent contact by persons with parts made live from the electric vehicle supply equipment or the electric vehicle battery.
     
 (D) Unintentional Disconnection: The electric vehicle coupler shall be provided with a positive means to prevent unintentional disconnection.
(E) Grounding Pole: The electric vehicle coupler shall be provided with a grounding pole, unless provided as part of a listed isolated electric vehicle charging system
(F) Grounding Pole Requirements: If a grounding pole is provided, the electric vehicle coupler shall be so designed that the grounding pole connection is the first to make and the last to break contact.
Electric Vehicle Inlet: The device on the electric vehicle into which the electric vehicle connector is inserted for power transfer and information exchange. This device is part of the electric vehicle coupler. For the purposes of this Code, the electric vehicle inlet is considered to be part of the electric vehicle and not part of the electric vehicle supply equipment.

Charging Connector Industry Standards
Society of Automotive Engineers (SAE) Recommended Practice is intended as a guide toward standard practice and is subject to change to keep pace with experience and technical advances.

SAE J1773 – SAE Electric Vehicle Inductively Coupled Charging-
Two major standards for power connectors are SAE J1772 and CHAdeMO. For standardization within North America, in October 2012, the Society of Automotive Engineers (SAE) completed a new standard connector, SAE J1772 Combo, which combines AC and DC charging capability (figure 6).[1] Major Japanese EV manufacturers use CHAdeMO; fast charging stations with these connectors are located throughout the United States and 50 other countries.[2] This standard of electrical connection has an additional charging method that uses the DC pins in the CHAdeMO connector for DC fast charging.[3] Additionally, Tesla, Inc. has a DC charging connector unique to its vehicles and charging stations. These unique connectors can use adaptors, which attach to the connector to charge at SAE J1772-type stations.[4]

Operation of a J 1772 charging station
When the charging connector (see Figure) is in its holster on the station, both it and the cable are completely de-energized and cannot be energized. When it is inserted into the E V socket (see Figure 4), the connection is detected by the charging station, which communicates its maximum current to the E V.

Pune Municipal Corporation (PMC) plans to set up 500 EV charging stations

Image
  Pune Municipal Corporation (PMC) plans to set up 500 EV charging stations in the public areas of the city. PMC has also selected locations for the set up of charging stations which includes municipal gardens, educational institutes, and main roads. PMC has issued tender for the same and private agencies too can bid on the setup. It plans to charge a minimal fee for charging vehicles and the amount earned will be used to maintain the stations. The implementation of the project will take place on a revenue-sharing basis. PMC will provide the required space for private owners to establish the stations and other arrangements can be made by the companies. Setting up new EV charging stations will boost the adoption of electric vehicles in the city of Pune. In Pune and Pimpri Chinchwad, people are buying more electric vehicles than electric rickshaws, and hence e-rickshaws couldn’t make an impression in the city. But officials believe that e-rickshaws have a brig...

Electric vehicle charging per kilometre 60 paise

  The Ministry of Power has previously announced new EV charging infrastructure standards and guidelines. In compliance with the rules, the state government has fixed the ceiling cost of service charges to be charged by electric vehicle public charging stations. It approved the Rs 12.06 + applicable GST service cost maximum for electric vehicle rates covered by State/Central subsidies. it is still less expensive than petrol and diesel. “It costs Rs 300 if any four-wheeler takes 25 units to completely charge their cars.” “You can’t even get three litres of petrol with the same quantity of petrol,” Car comparison between petrol, diesel and electric vehicles If the price of petrol is considered at Rs 100 per litre and mileage is considered 16 km per litre, the cost of the car, per kilometre, will be about Rs 6.25. If the price of diesel is considered at Rs 95 per litre and mileage is considered 22 km per litre, the cost of the car, per kilometre, will be around Rs 4.31.  ...

Lithium battery business training

  Some dramatically different approaches to EV batteries could see progress in 2023, though they will likely take longer to make a commercial impact. One advance to keep an eye on this year is in so-called solid-state batteries. Lithium-ion batteries and related chemistries use a liquid electrolyte that shuttles charge around; solid-state batteries replace this liquid with ceramics or other solid materials.  At the same time, concerns about supplies of key battery materials like cobalt and lithium are pushing a search for alternatives to the standard lithium-ion chemistry.  In the midst of the soaring demand for EVs and renewable power and an explosion in battery development, one thing is certain: batteries will play a key role in the transition to renewable energy. Here’s what to expect in 2023. The global battery value chain, like others within industrial manufacturing, faces significant environmental, social, and governance (ESG) challenges Environmental:  The ex...
