Usually they do not divide power into half, the first plugged in car gets whatever it requests, the second plugged car gets the remaining, when the first car reaches higher SOC it takes less power, all the freed up power goes to the second car. I think this is a better way instead of holding both cars, the first car is charged faster and leaves early. | |

| ![]() Fabulous car but honestly, for an average user, spending 50+L on a Kia is a bit of a bummer. Hope they're able to reduce the duties or reduce the prices somehow and it should be a good car to buy. |

Too light for my liking, and I felt the EV characteristics along with the light steering will need some getting used to. Hence my reference of taking a turn in neutral in IC equivalent. Quote:

I feel like people have taken a complete U-turn on the BMW kidney grilles of late. Even the purists HATED the front end. Also, don't forget that you need to spend an additional 5L to get the M Sport kit. Otherwise, the i4 looks like this. ![]() if we leave the badge aside, does this really look worse than that? ![]() BEVs are taking the brand out of the equation I feel. It's more about the platform. Yes, we can argue that our infra hasn't even caught up to the potential of either of these cars, but the 800V architecture is far more advanced and hence more future-proof. The only BMW EV I'd ever consider is the iX and sadly that's way out of most people's budget. Considering our duties, carmakers are doing what they can. With a market of 17k cars a year, we are lucky to have any of these options. Otherwise, it'll just be Nexons and ZSs in the market for us. Our market is too small to manufacture EVs locally at the present time. Even CKD operations would still cost companies a lot more than they'll earn. Kia, Hyundai, Volvo, BMW bringing in much more affordable cars is definitely a sign of good things to come. Hopefully in a duty cut, maybe even local manufacturing to some extent. It is tougher to do with a BEV. Maybe cars like the XC40 and BMW ix3 which share the platform with ICE counterparts can be made here in CKD guise. Only time will tell though. As of now we are paying extra for being first movers in the market. Quote:

The biggest difference will be some features will be cut from the CKD versions as has almost always been the case. EVs are generally more expensive than their petrol counterparts. Will be interesting to see Kia and Hyundai's made in india C-SUV EVs coming in 2025. | |||

For a typical lithium cell, the first phase of charging is constant current and after the set voltage is reached, it shifts to constant voltage and starts ramping down the current. So in EV6, the battery voltage is 800v but the charger like the one posted a few pages back can only supply 750v. So if the car was charged with only 750v, it would never achieve 100% SOC. So the cars on board DC-DC converter will have to boost the voltage. But there is no free lunch, you can have a charger with 1000v and 350A or can have a charger with 500v and 700A both result in 350kw of charging power. But a 180kw charger (like the one posted a few pages back) with boosted voltage from the cars onboard DC-DC cannot magically make up the remaining 170kw. If you use more volts, you can get away with less heat and smaller diameter wiring, PCB traces etc. So as long as the components can handle higher voltage, it's more efficient to get power from using more volts then using more amps. | |

Let's just take one single lithium polymer cell. It has a nominal voltage of 3.6v (approximately 60% soc) and fully charged voltage of 4.2v (100% soc) and a low voltage cut off of about 2.8v (0% soc). SOC is State of charge. Now to charge a cell, in order for the current to travel from the charger to the cell, you need to have a voltage higher then that of the cell voltage. If the charger voltage is less then then that of a cell, it cannot charge the cell. So in the KIA EV6 because of its very high battery pack voltage, a charger which has a lower voltage cannot charge the battery pack to 100%. Since not all chargers are the same with regard to voltages and as car manufacturers come out with even higher battery pack voltages, how can a new EV get charged from a legacy or old chargers with lower voltage? Answer: They use a on board DC-DC converter. A DC-DC converter can trim incoming DC voltage or Boost the incoming DC voltage depending on the design of the circuit, some can only trim aka buck and some can boost the voltage and some can do both. How do we get watt (power). In electrical terms you get watt by volt x Amp(current). In the previous pages the charger had the specs 750v and 200A max. So with this info, we can conclude that it can charge at 150kw of power. But the KIA EV6 is capable of charging at 350kw and its battery pack is 800v. So either you bump up the volts or current to increase the charging power. Without doing this you cannot magically create sustained high charging power.

| ![]() We should give the credit to Kia where it is due. I had never thought I would see the day when a Kia was being compared to BMW - either in terms of features, price or desireability. Kia has come a long way since being branded as the cheaper version of a Hyundai. Reports in the Economic Times today in an interview with Mr. Tae-Jin Park states that Kia EV6 has already received 355 bookings which is 3.5 times more than the allocation of 100 units. Do we have reports of how many units the BMW i4 has sold in India? |

| ![]() What an amazing car at a fantastic pricing. If it were launched as a CKD, I wonder what the price would be. Great to have such a good car in India |

| ![]() Love the car how it looks and being a CBU, 60 Lakh is a decent price. BUT having the i4 being announced at 69.99 Lakh, I feel KIA got themselves in a difficult position here. The higher specs and technical side aside (And the ugly grill too ![]() |

| ![]() Honestly this hot debate seems somewhat futile as the entire lot for both these cars was probably sold out for the year before bookings even officially opened! |
