Re: Ather's charging connectors are incompatible with other EVs I have been doing some research as I had booked an ather 450x. My findings.
There is three kinds of charging according the major international standards ( ccs2, CHAdeMO, tesla, GB/T) A/C Level 1 & A/C Level 2 (Home usually ) :In both A/C charging the thing people refer to as a charger is usually just a power outlet with some safeties built in. The charger is inside the car . Level 1 is somewhat obsolete and everything new is usually level 2. D/C (Chargin stations ) :this is the fastest standard and as it developed mainly for developed countries with little two wheeler usage they have no support for 48-72v and they only support high voltage 300 –1000 volts .
Now most cars in India including most tata and every other electric cars use those standards , however that is not so for scooters they are different in both A/C charging as well as d/c fast charging Scooter Home charging : its similar to the standardised Level 1&2 except that the charger is outside , so you are actually giving the scooter DC power, but at 48-90v unlike the international dc standards. I think this is being done to reduce the weight or save space inside scooters/bikes..Its slow takes 4-6 hours for a scooter. Charging stations : 48-90v but at much higher current to charge the vehicle in one hour or less.
Indian Government is aware of it. They have extended Chinese GB/T and built a standard called Bharat 001 . It uses same connector as Chinese GB/T which is supporting power levels similar to international standards . Indian standards extends these by having low voltage D/C fast charging .
The new Tigor ev runs on low voltage , 72 volts and has a GB/T connector it can also fast charge ,, so it is getting there . I have yet to see a combined charger that supports both low-voltage-dc-GB/T and high-voltage-dc-GB/T together but everything necessary seems to be in place . As its compatible voltage vice Ather finally can make an adapter for Bharat-001 with Gb/T adapter if they want to , they needn't do voltage conversion like international standards , only translate the communication protocol.
The Ather connector looks like the old European one , so it may be using the powerline standards for communication , whereas the Chinese standards use CAN bus. A small MCU for translation maybe the only thing that's needed for making adapter .
PS: I personally find the Tesla's standards most advanced and elegant but expensive to implement , but the Chinese exceeds everything else in specs and is also cheaper for everyone , CCS2 isn't exceptional in anyway. The idea of extending the Chinese standards to include lower end EV was a brilliant idea in my opinion .
