The false standard of new energy vehicle battery life can be said to be an "open secret", and the gap between the apparent battery life and the actual battery life is generally large in different circumstances.
There are currently four endurance standards for new energy vehicles, EPA, WLTP, NEDC, and CLTC. In terms of the level of energy consumption required to cope with the test, from low to high, it is CLTC≤ NEDC< WLTP<EPA. At present, domestic manufacturers are basically based on CLTC, but no matter what kind of battery life standard, it is difficult for you to run the nominal battery life performance.
And the battery life is also greatly affected by external factors, and there are many variables. For example, the speed of 60 per hour and the speed of 120 per hour, the battery life that can run out is very different, and the high-speed battery life is often the short board of electric vehicles, often only six or even five folds. Another example is the temperature, in the case of low temperature, the range of electric vehicles is also more obvious, and it is normal to cut in half.
However, many people tend to only pay attention to the false standard of battery life, but often ignore the virtual standard of fast charging. In fact, the fast charging virtual standard of new energy vehicles is the same as the false standard of battery life, you will never be able to run the peak power and charging time called by the manufacturer, and the virtual standard of fast charging is worse than the false standard of battery life is "two-headed deception".
First of all, on the side of car companies, it is very chicken thieves when promoting fast charging time, and they often use 30-80% of the charging time to focus on publicity, why, because this is the highest range of electric vehicle charging power, but ah, there is an obvious problem with electric vehicles, when the power is low, and when the power exceeds 80%, the charging is relatively slow, especially the trickle charging after 90%, unless you only use it at the stage of 30-80%, which also means that you can only use 50% of a car of nominal battery life.
Secondly, even if you charge in the 30-80% range, you will not be able to achieve the peak power declared by the car company, because there are many reasons for restrictions, such as the peak period of electricity consumption, the power can not be reached, for example, to use the corresponding brand of the corresponding model of charging pile, the same charging station can not have multiple new energy vehicles charged at the same time, because a simultaneous charging will be diverted. Even if all the ideal conditions are met, you find that you still can't reach the peak power claimed by the car company, you have to ask why? The final interpretation is in the hands of the car company.
Finally, many charging piles also have the problem of false standards, when we charge the charging pile, we often find that the nominal power can not reach half of the situation, for example, once I drove a new energy vehicle to charge, found that the mobile phone APP shows that the charging power is 180KW, but the actual charging power is only 60KW, and finally found that the rated output power marked on the metal nameplate on the back of the charging pile is 120KW, and the rated output power of the single pile is 60KW, which is seriously inconsistent with the data displayed by the APP, and there is a false standard phenomenon.
The summary is that in order to achieve the charging power advertised by car companies, it must be in the right pile, the right time, and the right amount of power, and it is completely impossible to achieve the fast charging speed advertised by car companies under realistic circumstances, which is simply more serious than the battery life false standard, because in the right road conditions and temperature, it is possible to drive 1 to 1, or even exceed the actual battery life of the car company's nominal battery life, but the charging speed is basically impossible.
In fact, for the current electric vehicles, the mileage is no longer the key, the nominal range of more than 600 kilometers is enough, and the most important thing is the charging time. If this problem is not solved, it will be difficult for electric vehicles to truly replace fuel vehicles.
