Interesting info here (Hyundai misleading advert):
The Advertising Standards Authority has found that adverts from Toyota and Hyundai giving electric vehicle battery charging times were misleading.

"Hyundai described how the Ioniq 5 could be charged from 10-80% in 18 minutes on ads appearing on a digital billboard, a YouTube video and in a marketing brochure.
However, the ASA received several complaints arguing that there were significant limitations to achieving the advertised charging rate, including low temperature.
Hyundai said that the ads were intended to help address consumer concerns about charge times affecting longer journeys.
In its defence, it provided the ASA with results of their internal factory testing of the charging times for both Ioniq 5 battery options (72.6kWh and 58kWh).
They stated that testing established a time of 17 minutes and 16 seconds to charge the battery from 10% to 80% when using a 350 kW ultra-fast charger, and with the battery at temperatures of 22 and 25 degrees centigrade.
In the advert which appeared on YouTube, Hyundai said not including a reference to ultra-fast charging was an oversight and the ad had now been removed.
It also argued that the average consumer, particularly one contemplating adopting an EV, would be aware that "ultra-fast" 350 kW charging indicated a higher speed charger that was different from fast, standard or slow charging.
Hyundai said they would be willing to amend the claims that were subject to the complaint in its brochure to make clear that charging time could vary from 18 to 36 minutes and was dependent on being connected to an ultra-fast 350kW charger.
It would also qualify the claim to state that charging times would increase at lower battery temperatures, and that charge times were dependant on a number of factors including battery temperature, condition and age, ambient temperature and the power provided by the charger.
It also proposed to include text informing consumers that ultra-fast 350 kW chargers were currently available on selected motorways/major arterial routes, excluding Northern Ireland.
The ASA acknowledged that the evidence provided by Hyundai showed that, under standardised testing conditions (with a new battery and in a temperature-controlled environment with ambient temperatures of 22 and 25 degrees centigrade) the battery could be charged from 10% to 80% in under 18 minutes using a 350kW charger.
However, it said it would expect Hyundai to qualify the charging claim with an explanation of the conditions under which the figures were achieved and that they may not reflect actual consumer experience.
As a result, it ruled that the claims had not been substantiated and were misleading, and the adverts must not appear again."
