The 73kWh battery pack runs 700km of range, how much is the range of Xiaomi SU7?

Buying a tram is a science, and the new industry reveals countless marketing gimmicks of capital.

If it's just a small car priced at tens of thousands of yuan, it's really no problem to pay for marketing and faith, but a pure electric vehicle with more than 200,000 yuan at every turn is definitely not a "good-looking" and "like" that can solve some objective problems.

Regardless of how Lei Jun marketed, the questions in front of Xiaomi SU7 are very straightforward:

1. 400V is backward when it is listed, in this era when more than 200,000 mainstream models are 800V, 400V is not only lagging behind in product power, but also means that after having large-scale mass production capacity, after a large number of new Xiaomi new cars enter the market, high-priced 400V products will definitely have the problem of collapse in value retention.

First of all, ask you, whether your wallet can withstand the later plummeting value retention rate, at least in the current tram industry, I have not seen a model with a real high value retention rate, the most criticized by the tram user group is: buy expensive, sell cheap.

2. The 73kWh battery pack, how to run 700km+ endurance results.

This is extremely misleading, because there are several basic conditions for wanting to achieve a range of 700km+, one is the test process of full charge and discharge, and the power is from 100%-0%, and the other is that there is a huge gap between laboratory data and daily use.

Of course, this is something that everyone knows, but there are other things that people don't know.

In the process of daily use, it will never give you the opportunity to fully charge, the charging recommendation of the vehicle is only to 90%, and some cars are recommended that you charge to 80% to avoid overcharging, and at the same time you should also reserve 10% of the power to avoid lying on the nest halfway.

Do you think that's the end of it? There's also an engineer's logic in it: "The tram will lock up 10% of the battery", the purpose is to force to avoid irreversible damage to the battery caused by overdischarge.

In fact, the driving power that the whole vehicle can provide to users is only about 70%-80% of the battery pack.

A normal 5-meter-class, 2-ton tram consumes about 14 kWh per 100 kilometers in summer and 18 kWh in winter. It is easy to calculate that Xiaomi's 73kWh power can only run 420km in summer and about 330km in winter.

From the perspective of engineering logic and the status quo of 400V, the pricing of the Xiaomi SU7 is not low, although its positioning is obviously a sporty style product, but this also means that the user group is defined as young people who love sports.

If a car cannot enter the real market, it is difficult to sell.

One reason is that the budget of more than 200,000 is not a lot, and there are quite a lot of products to choose from, from traditional BBA to a large number of 800V products, the uniqueness of Xiaomi SU7 is extremely weak.

The other is,Positioning movement actually can't attract too many people,In the case of urban use,Performance and control are seriously inhibited,What users need more is convenience、space、Comfort,This is very unfavorable for Xiaomi SU7 that comes up to play the sports card。

We said before that the amount of lock orders of Xiaomi SU7 is actually not ideal, at least not as hot as imagined, which is still based on a large number of Xiaomi interest chains, bloggers, and fanatical fans.

Because of the slow delivery time, in the next few months, power batteries, cost manufacturing, new products of competing products and even BBA will continue to reduce prices, which will have a direct impact on Xiaomi SU7, which cannot be delivered on a large scale for the time being.

It is bound to lead to a phenomenon: users who have locked the order may give up the 5,000 yuan deposit and choose better and cheaper other products.

In the automotive industry, Xiaomi is facing Chinese companies that are rising one by one and have more production, design, and R&D capabilities, rather than the arrogant and joint venture mobile phone players that Xiaomi faced when it was just starting out more than ten years ago.

If you want to really push Xiaomi cars to new heights, Lei Jun's road is extremely difficult.
