Introduction
As per the report (The Time of India) India is the second polluted country in the world. IC engines are one of the major factors polluting the environment and to minimize the air pollution as well as increasing the efficiency of the vehicle, most of the OEMs are moving towards electric vehicles. Since every innovation has its Two faces, it also has its own merits and demerits. Electric vehicle industry is lagging in terms of charging time and the available infrastructure for Electric Vehicle Charging.
E-Fill Electric (EFEV Charging Solutions PVT. LTD.) comes with the complete solution for the Electric vehicle ecosystem as we are providing DC fast charging along with Smart CMS feature which takes 1 to 2 hours maximum Charging time.
Target of DC charger
The trend of electric vehicles is increasing rapidly all over the country. Electric vehicles are becoming increasingly popular around the world. In order to leverage the market potential, the major players in the DC Chargers market are also taking several strategic steps, such as product development and product launches.
Today with the increasing number of EV, there is a need for a better charging infrastructure and number of charging stations at specific distances. E-fill Charging Solution are fulfilling the market need and installing AC & DC Charger in different ratings in all over the country. So, an EV customer can use these smart chargers without any hassle.
Working of DC Charger
DC charger helps with fast charging in electrical vehicles. DC chargers are battery charged with DC electric power while most electricity is delivered as compared to AC power. Because the DC charger is Off-board charging, electric vehicles are on-board charged. First, an electrical vehicle converts AC to DC with the help of a rectifier then delivers current to the battery. but the DC charger bypasses the EV circuit and directs the delivered DC to the battery. DC charger is fully implemented and certified International standard DC charger multi types of connectors and Kilowatt. We are an OEM, (E-Fill Charging solution Pvt. Ltd) provide a Charging Station in Different Range of Kilowatt 15KW, 30KW 60KW and 120 KW.
DC charger is an Easily handshake to different electrical vehicles. A charger is a converter to AC to DC and delivered to supply EV batteries. CAN tool is used to communicate between EV and EVSE, monitor of SOC. Main Controller cards are set of Current and voltage according to SOC in electrical vehicles. That is, each other is easily monitored by CMS and checks the data log.
DC Charger used in multiple Plug connector
There are types of Guns used in DC Charger
- CCS- Combo 1 and Combo 2
The socket is the combined charging used in AC and DC. IEC 62196-1, IEC 62196-2 and IEC 62196-3 standards used to DC charging connector. It has 5 pins used in gun, Control Pilot has used both types of communication low level and high level. CCS Sockets are present in Tata EV, Nexon EV etc. It is maximum current is 350 Amps and voltage between 200 to 1000V.
- ChAdemo
ChAdemo is a Japanese manufacture. It is used Standard IEC 61851-23, 24. It has 3 power pins and 6 signal pins. It is used by CAN protocol in communication for signaling. Its maximum current is 400Amp and voltage range is 1000V to 400KW.
- GB/T
GB/T is a Chinese manufacture. It used the GB/T 20234-2015 standard and the connector used a CAN bus communication. It has 5power pin, 2 pin DC pin, one pin Earthing, 2 CAN pin and 2 is Auxiliary power. Now maximum current is used 250Amp and voltage range is 750V or 1000V.
Communication Protocol
∙ Electric vehicle specification the EV Charging is communication that is the need of between electrical vehicles and EVSE.
∙ DC charger communicates BMS of EV batteries, to enable the charging and maintain SOC of the battery. CAN device is used for physical communication between electric vehicles and EVSE.
∙ DC Fast charger is easily communicated by CMS and EVSE so as to be easily controlled depending on the rate of grid supply. CMS use Data log, check the status of charger and full control of EVSE.
∙ The communication Protocol used OCPP 1.6J Standard. It carried WIFI, Network, Ethernet and GPRS.
∙ It is easy to communicate with another network.
∙ All networks provide and operate on websites and mobile applications.
∙ EV to interact with Different Charger. Communication and safe handshake between EV and EVSE. Easily to analyse the log data.
Difference Between AC vs DC Charging Station
Common Difference in AC and DC Charging Station. DC Charger has faster charging than AC Charger, Because DC Charger is bypassing the EV Circuit and directly charging to the Battery. DC Charging Station is a more expensive installation than AC Charging Station. DC Charger consumes less time than AC Charger for charging the Electric vehicle.
Features of DC charger
∙ Authentication by RFID & OTP.
∙ Three phase input supply.
∙ No. of output DC – In which 0ne, Two- & Three-Gun Socket are required.
∙ Design – Easy understand, flexible configuration which are easy in field upgrade,
∙ Mode of payment – Swipe card, QR code and mobile application.
∙ LCD Display- Touch screen display and smooth working.
∙ Description- Wall Mounted & Mounted on stand in which easy move from one place to another according to the convenience.
∙ Protection – short circuit, over Voltage, over temperature, under voltage, lighting, SPD, leakage, surge protection, ESD etc all protection Flow the IEC 61000 Standard.
∙ Official App use online and offline which help to find out the location where charging point Installed & which location to be near or suited according to the user’s time.
Advantage of DC charger
∙ DC charger is Very fast charging compared to AC charger.
∙ DC charger is Friendly connected to different EV (Nexon EV, Tata EV etc).
∙ It is easy to connect to a different Server.
∙ Cost of EV charging is less than an IC engine.
∙ DC chargers are providing many types of safety electrical.
∙ No need for maintenance.
Future Planning
The E-Fill Charging solution is coming up with a 120 kW DC Charger for Electric Buses and many interesting products in future.
