When you are ready to buy a new energy vehicle, is your first reaction to look at its cruising range first?
Admittedly, this consideration is correct, but at the end of the day, battery life is only a superficial effort.
Why?
Because a friend in the industry recently reminded me, I realized that things are far from that simple.
To put it bluntly, don't let the word "battery life" confuse you, there are more factors worth paying attention to when buying a tram!
01 Why don't you just look at "range"?
On this point, many people may think that I am talking nonsense: because range is not important, what else is important?
But the reality is cruel, only the cruising range, and the ideal cruising effect cannot be achieved.
At the end of the day, buying a new energy vehicle is a bit like buying a house: the advertised 100 square meters looks tempting, but once you include the shared area, the actual usable space is greatly reduced!
In the same way, if you only focus on the mileage, it is often easy to be "pitted".
This is not alarmist, just search for keywords such as "battery life", and you can see a screen full of complaints.
Some people complain that the nominal endurance of 1200 kilometers can only run more than 500 kilometers;
Others say that the battery life is 5% off;
Some people even found that the car they bought back could only run to four folds - they really wanted to cry without tears!
Moreover, this situation is definitely not unique.
Take my experience of setting off at the same time as a friend:
At the start, everyone had a similar range, but by the time we reached the finish line, my car could still run 120 kilometers, and he broke down halfway through!
You say, who is this for, can you not be angry in your heart?
I must be fooled and want to find trouble with the car company!
Unfortunately, complaints about such issues have hardly yielded substantive results.
Because the manufacturer always has something to say, the battery life advertised is just a reference, and everything is subject to reality!
So, in order to avoid losing yourself, don't just look at the range.
02 So what parameters should you pay attention to?
Since the range may be "discounted", what should be paid attention to?
Overall, there are a few key points!
Because anything can be faked, this thing can't.
To put it bluntly, a large 100-degree battery will certainly run farther than an 80-degree one, with few exceptions.
At the same price point and model, choosing a car with a larger battery usually yields better results.
When you go for a test drive, you can see what the average energy consumption of the tram is.
Generally speaking, 15 kWh per 100 kilometers is a good standard.
If the energy consumption can be as low as 12-13 kWh, it is very good, and the actual performance will be very good.
On the contrary, if some trams soar to 18 degrees per 100 kilometers when driving in urban areas, then try not to buy such cars.
This is a typical "electric Luxgen", and the power consumption is amazing!
Trams with 800V technology in the whole range usually consume less energy and consume less energy.
After all, at higher voltages, the amount of heat generated as the current passes through is reduced, resulting in lower energy losses.
At the same time, a car with a good electrical architecture has a higher degree of system integration – one system can manage multiple devices.
Because management is more straightforward, power consumption is also reduced.
As for what the media evaluates, the reference value is not large.
Because evaluation agencies also have to survive, these data are the result of "human intervention".
03 What can't be ignored?
In addition to range, energy consumption and electrical architecture, there are several key factors that are equally important and should not be overlooked.
It is not only necessary to look at the steel materials used in the body, but also to pay attention to the design concept.
In principle, it is best to buy a model with "battery-body integration".
Compared with the traditional structure, this design allows the battery and the vehicle to become a whole, which greatly enhances the collision avoidance ability.
Because the "compressive capacity" of the side pillars of this type of car can reach 80 tons, not to mention the front and rear.
In such a situation, even in the event of a serious car accident, the risk of battery fire can be effectively avoided.
It can be not very intelligent, but it must be stable.
Because electric cars are different from gasoline vehicles, the emphasis is on "software-defined vehicles".
If the software is unstable, it will cause the vehicle to fail to unlock, and even various problems such as black screen and freeze.
In addition, from the perspective of durability, with the continuous push of OTA (over-the-air upgrade): car companies with poor software optimization capabilities will become more and more stuck, and the stability will become worse and worse.
After all, some trams charge only 50 kilowatts, while others can reach 500 kilowatts, a difference of ten times!
Of course, with a limited budget, not everyone can afford such a good tram.
But in principle, the charging power should not be less than 120 kWh.
Because the level of mainstream charging piles is around 120 - this requirement is not met, it is too uncomfortable.
All in all, buying a new energy vehicle needs to be carefully considered - range is important, but it is only the tip of the iceberg.
If you only focus on this point, you tend to ignore other, more critical factors.
Is this clear to everyone?
