AC and DC Charging Explained:
- AC (Alternating Current) gets converted to DC (Direct Current) either outside of the car (for AC chargers) or within the charger plug-in itself (for DC chargers).
- Electric vehicle (EV) batteries in North America only accept DC, requiring chargers to always be AC/DC or solely DC.
- In Europe and Japan, EV batteries can be charged using only AC.
New Made-in-India EV Charging Standard:
- The standard, ISI7017 was developed by Indian organizations including NITI Aayog and Ather Energy.
- It’s a world-first standard combining AC and DC charging for Light Electric Vehicles (LEVs).
- It aims for interoperability, meaning it can be used across different EV models and charging stations.
- However, it’s not mandatory for EV makers to use this uniform standard, potentially leading to range anxiety.
Need for a National Charging Standard in India:
- Currently, different EV makers in India use various charging standards.
- This situation is similar to the different charging ports used by Apple (Lightning) and Android (USB Type-C) phones.
- Lack of a unified standard results in range anxiety and challenges for public charging stations.
Global Standards in EV Charging:
- China: Uses the GB/T national standard and has a dense network of charging stations, effectively reducing range anxiety.
- United States: Lacks a national standard, but some major manufacturers like Ford and GM are aligning with Tesla’s North American Charging Standard (NACS).
- Europe: Predominantly uses the Combined Charging System (CCS) standard, also an EU requirement for EV charging networks.
- Japan: Relies on the CHAdeMO standard, established in 2010.
Why in News:
- The Bureau of Indian Standards (BIS) has approved an indigenously developed AC and DC combined charging connector standard for light electric vehicles (LEVs).
