One must have even considered purchasing an electric vehicle (EV) as their future vehicle given the rising popularity of EVs. Even though EVs may cost more to buy than conventional ICE vehicles, their ongoing operating costs are far lower. Urban or high-rise residents may be able to have an electric charger installed in their parking space. Alternately, you can use public chargers for quick charging.
Those who are familiar with the fast-charging procedure have probably noted that manufacturers only state the charging time from 0% to 80%, not for a full charge. Exactly why not? To clear up our doubts, we had the Hyundai IONIQ 5 with us as a test vehicle. The specifics of fast-charging an EV are as follows:
With The Hyundai IONIQ 5, Observations
We brought the IONIQ 5 to a Shell station with a 120kW rapid charger on Sus Road in Pune, Maharashtra. We plugged in when the battery had 25% of its capacity left to see how long it would take to fully charge
The IONIQ 5 required three to five minutes for every 10% of charge added up to 80%.
You can charge an electric vehicle to 80% of its capacity with a 120kW charger in 30 to 40 minutes.
However, it took over 20 minutes for the subsequent 10% charge to be applied once the charge reached 80%.
Another 15 minutes were spent on the 90% to 95%.
The driver's display indicated a range of 447 km in Eco mode, 434 km in Normal mode, and 420 km in Sport mode with the charge at 95%.
Why Did It Take So Long To Charge More Than 80%?
The IONIQ 5 charged at its maximum rate of 120 kW up to 80%, but after that, like all other electric vehicles, the pace reduced to 10–20 kW. Regardless of the type of rapid charger, the power will reduce to 10-20kW after 80 %.
The battery begins to heat up during a fast charge cycle, which is the main cause of the 80 to 100 % charge taking longer. Low-speed charging helps the battery cool off because prolonged high temperatures are unhealthy for it. Longer periods of high voltage cannot be tolerated by lithium-ion batteries since the health of the pack will gradually deteriorate.
Your smartphone may have gone through a similar thermal phenomenon where it got hot from fast charging frequently from a low percentage. Consider packing your bag as you normally would: filling it up to 80%, or the suitcase's edge, with clothing. Once you get to that point, you have to analyze the additional packing, which takes more time.
Up to 80% of the time for every electric vehicle, the battery cells charge up unevenly. Beyond 80%, however, the cells charge consistently to capacity. The charging speed is intentionally decreased by the system while it is identifying and recharging the cells. The clever detection system is also included in iPhones, which charge swiftly up to 80% of the way before slowing down.
Now, a fast charger does not necessarily need this charging technology. Since the majority of AC chargers have a capability of between 7kW and 11kW, the voltage will likely only decrease somewhat. These are the explanations for why most manufacturers only list 0% to 80% or 10-80% fast-charging times.
