Very demanding CO2 emissions and environmental issues push car manufacturers to quickly develop electrified vehicles. <\/p>\n\n\n\n

However, the electric vehicle market is currently faced with certain technical constraints on its batteries<\/strong>, which sometimes act as a brake for consumers.  <\/p>\n\n\n\n

Among the major obstacles, here are 3 main pain points according to a study by Castrol based on an opinion research on 9 000 consumers, 750 fleet managers, and 30 automotive industry professionals in 8 countries – <\/strong>the United States, the United Kingdom, Norway, France, Germany, India, China, and Japan:<\/p>\n\n\n\n

1. The current price<\/strong>
2. The time it takes to charge an EV<\/strong> (major importance for 68% of the consumers) 
2. The range <\/strong><\/p><\/blockquote><\/figure>\n\n\n\n

But that was before, because battery immersion cooling technology<\/a> has the cards in hand to remove some of these constraints. We\u2019ll see why. <\/p>\n\n\n\n

First, let\u2019s have a closer look on the consumers\u2019 expectations and the challenge for OEMs to meet it despite many constraints. <\/p>\n\n\n\n

The consumers want a better price, a faster charging time and a longer range <\/h3>\n\n\n\n

1. Better price <\/h3>\n\n\n\n

The price of an EV is the biggest pain point for consumer<\/strong>. The \u2018tipping point\u2019 for global adoption is estimated at $36 000<\/strong> by Castrol’ study. <\/p>\n\n\n\n

Nowadays, the price of an EV battery is mainly impacted by its size, which is one of the big strengths of immersion cooled batteries<\/strong> that can lead to smaller batteries because they are far more efficient.<\/p>\n\n\n\n

2. Charging faster <\/h3>\n\n\n\n

Escalent<\/a> conducted a study over 2,500 individuals in the US and figured out that for 50% <\/strong>of them, charging speed is far away the most important aspect<\/strong> people are looking for public charging. This is almost twice as important as having a location along their route (26%).<\/p>\n\n\n\n

This shows that the time it takes to recharge an EV battery andrange anxiety<\/u><\/strong><\/a> are major pain points for consumers. As illustrated on top, charging time is definitely the second most important criteria for the EV drivers<\/strong>. <\/p>\n\n\n\n

Nowadays, the time charge \u2018tipping point\u2019 is about 31 minutes <\/strong>for the consumers, which means they would globally be ready to buy an EV if the total charging time doesn\u2019t exceed 31 minutes. <\/p>\n\n\n\n

Nowadays, most OEMs are unable to afford a fully charge battery in less than 30 minutes. <\/p><\/blockquote><\/figure>\n\n\n\n

3. Longer range <\/h3>\n\n\n\n

For the consumers, the range is the third most important criteria. To achieve the global adoption of the market, electric vehicles would need to reach a 469 km range.<\/strong> <\/p>\n\n\n\n

As well as being 3 major concerns for the consumers, price, charging time and range are some of the biggest challenges for OEMs and manufacturers in the years to come. <\/p>\n\n\n\n

Among these 3 concerns, the charging time crystallizes all these aspects<\/strong>.<\/p><\/blockquote><\/figure>\n\n\n\n

Indeed, reducing the charging time means reducing the range anxiety<\/strong> as it would take less than 10 minutes to recharge a battery, people are no more afraid to stop for recharging. It is also possible to have smaller batteries, therefore the weight and the cost of a battery are reduced which results in a positive environmental impact.<\/p>\n\n\n\n

Faster charging time and battery safety : 2 main challenges for OEMs to meet consumers\u2019 expectations <\/h3>\n\n\n\n

Nowadays, charging an EV battery up to 80% in less than 30 minutes with current battery thermal management technologies without significantly reducing the battery’s lifespan is a challenge for manufacturers. <\/p>\n\n\n\n

To meet the consumers\u2019 expectations and reach 10 minutes charging time instead of 30+ minutes, two parameters need to be closely monitored<\/strong>: <\/p>\n\n\n\n
