Hello everyone, I am the glacier of cold outside and hot inside, the vigorous development of the electric vehicle market has brought about the diversification of products, from family transportation models to meet the daily short-distance travel to electric vehicles with stronger endurance, consumers have more and more choices. However, among the many high-range electric models, we find an interesting phenomenon: even those high-range electric vehicles of well-known brands generally choose to carry 72v38ah graphene batteries instead of lighter, higher energy density lithium batteries. The reasons behind this choice are worth digging into**.
First of all, let's get to know the two major EV brands in the market – Yadea and Emma. These two brands have a very high market share in China, and their mainstream high-endurance models are Yadea E10 and Emma Navigator respectively. These models are equipped with 72v38ah graphene batteries, which are essentially graphene batteries despite their different names. When buying a car, dealers often advertise the superiority of graphene batteries and claim that these models have a range of up to 200 km. However, this propaganda may not be entirely accurate.
So, why do these brands choose graphene batteries over lithium batteries? There are three main reasons for this:
Cost considerations: The cost of lithium batteries is relatively high. If the electric vehicle uses a lithium battery to ensure a range of 200 kilometers, then the cost of each car will increase by about 1,000 yuan. For consumers looking for value for money, this can influence their purchasing decisions. In contrast, the cost of 72V38Ah graphene batteries is lower, making the best for electric vehicles more accessible to the people.
Independent R&D capabilities: Brands such as Yadea and Emma choose graphene batteries in part because they are able to develop and produce them in-house. Graphene batteries are based on lead-acid battery technology, and their R&D and production processes are relatively simple. Lithium batteries, on the other hand, require higher technical investment and cost. By independently developing graphene batteries, these brands are able to better control product quality and cost, thereby maintaining market competitiveness.
Safety considerations: Although lithium batteries have high energy density and lightness, they also have certain safety risks, such as the risk of spontaneous combustion. Although the probability of such a risk occurring is low, the damage to the brand image can be catastrophic. Therefore, in order to maintain brand reputation, big brands often avoid battery technology that can pose safety concerns.
So, can a 72v38ah graphene battery really achieve a range of 200 km? According to the official data provided by Yadea, the endurance of this battery is different in different driving conditions. At a speed of 30 40 km per hour, the maximum range can reach 120 130 km; At a speed of 25km h, the maximum range can reach 1669 km; And at a speed of 47 mphAt 8 km h, the maximum range is 112 km. These data show that the actual range of graphene batteries does not reach the advertised 200 km.
Although graphene batteries may not be as good as lithium batteries in terms of endurance, considering factors such as cost, self-research capabilities and safety, it is reasonable for brands such as Yadea and Emma to choose graphene batteries as the power for high-range electric vehicles. For consumers, when buying an electric vehicle, they should rationally look at the publicity of the merchant and choose the right model according to their actual needs and budget. At the same time, understanding the advantages and disadvantages of battery technology is also very important to make an informed car purchase decision.
