Now the diversification of electric vehicle products is a trend, in addition to dozens of kilometers of family travel models, some of the range of one or two hundred kilometers of electric vehicles, is also more and more common, but if careful friends will find a status quo, these big brands carry high-endurance electric vehicles, are equipped with 72V38AH graphene batteries, will not choose more conducive to high-endurance lithium batteries, what is going on?
Yadea and Emma's mainstream high-endurance models are equipped with 72V38AH graphene batteries
Yadea and Emma are currently the most mainstream brands of electric vehicles, with the highest market share in China, and the current mainstream high-endurance models of the two are Yadea E10 and Emma Navigator.
The electric vehicles of these two brands are all equipped with 72V38AH capacity batteries, Yadea is a graphene 3rd generation PULS battery, and Emma is a gold standard graphene battery.
Although the names are different, they are equipped with graphene batteries, and when buying a car, dealers advertise that graphene batteries are better, and they can last up to 200 kilometers.
Why would you rather 72V38AH graphene batteries instead of lithium batteries?
But to be honest, graphene battery is currently a relatively controversial type of battery, many people do not recognize graphene battery, on the other hand, the high density and high lightness of lithium battery, in fact, it is more suitable for carrying on high-endurance electric vehicles, then, why Yadea, Emma and other brands, would rather 72V38AH graphene battery, not use lithium battery?
1. Equipped with lithium battery, the cost of each car will be 1000 yuan
First of all, one of the most critical reasons is the price factor, the manufacturer is equipped with a 72V38AH graphene battery, which has been investigated at this price, which is acceptable to consumers, and if it is equipped with a lithium battery, if you want to last 200 kilometers, the price after configuration is unsatisfactory.
A set of 72V38AH graphene batteries, its price is about less than 2000 yuan, but equipped with lithium batteries, taking the same 48V48AH lithium battery that can last 200 kilometers as an example, the price is about 3000 yuan, which means that if you want to use lithium batteries, you have to add 1000 yuan to each car, and there are very few consumers who buy high battery life, which is to further compress the potential consumer group.
2. Graphene batteries can be self-developed
Yadea's Guanneng 3rd generation PLUS graphene battery and Emma's gold standard battery can be self-developed and self-produced, because graphene itself is a lead-acid battery, and the requirements for R&D and production process are not so high, but lithium batteries are different, and a lot of financial and material resources need to be invested in the research and development of lithium batteries.
3. For safety reasons, it will affect the reputation of the brand, and the gains outweigh the losses
The last reason, I think it is also considered by the manufacturer, that is, although the lithium battery is good, it has the risk of spontaneous combustion, although the probability is very low, but once it is said that a brand will spontaneously combustion, affecting the brand power, therefore, the big brands are reluctant to be carried, but some small brands, miscellaneous brands, very favored to carry lithium batteries.
These 3 reasons are why Yadea and Emma's high-endurance models would rather be equipped with large-capacity graphene batteries than lightweight lithium batteries, but the question is, can graphene, as a lead-acid battery, 72V38AH really be able to achieve a high endurance of 200 kilometers?
Equipped with a 72V38AH graphene battery, can it really run 200 kilometers?
As for the range of electric vehicles, it is generally introduced by dealers who sell cars, and in order to promote sales, the battery life they say actually has a certain amount of moisture, on the contrary, the battery life that manufacturers generally say is still more objective.
For whether the 72V38AH graphene battery can last 200 kilometers, the little expert found the objective data given by the Yadea manufacturer.
1. When driving at a speed of 30~40km/h, the maximum endurance is 120~130km in summer;
2. Driving at a speed of 25km/h, the maximum endurance is 166.9km;
3. Driving at a speed of 47.8km/h, the maximum range is 112km;
Through the data given by the manufacturer, it can be seen that the graphene battery equipped with 72V38AH can run less than 200 kilometers, so when buying a car, don't take it too seriously when you encounter the 200 kilometers introduced by the merchant without charging.
So, what do you think about high-range electric vehicles that like to be equipped with graphene batteries instead of lithium batteries?
