Recently, some media tested that “Xiaomi SU7 (parameters| Inquiry) A fully charged 73.
6-degree battery costs 87.
86-degree electricity “, which is a reverse false standard.
In response, Xiaomi Automobile’s official response said: This is not a “reverse false standard”, nor will it cost more electricity bills, but a true reflection of the real charge and discharge volume.
, Xiaomi officials said that there is a difference between the true “power”(including charge and discharge capacity) and the battery power marked in the product announcement.
In fact, the amount of electricity marked is tested and is not a fixed value.
, 
, 1C or 1/3C is commonly used in the industry to mark the battery power.
This “1C” or “1/3C” is the “discharge rate”, which refers to “how fast (several times the rate) it is discharged”: 1C is a fully charged battery, discharged at a fixed current, and discharged in 1 hour until it loses power.
1/3C is a fully charged battery, discharged at a fixed current, and discharged until it loses power in 3 hours.
, in accordance with the requirements of regulations, when Xiaomi SU7 was announced, it was declared in accordance with the 1C standard, so the battery capacity of Xiaomi SU7 standard version is 73.
6 degrees.
According to 1/3C discharge, the power that the Xiaomi SU7 standard version can discharge is 76.
8 degrees.
It can be seen that the amount of electricity discharged by the same battery varies according to different discharge rates.
At the same time, in daily operating conditions, the discharge rate is lower, the battery can discharge more electricity, and can also run more mileage.
, and there are more influencing factors regarding charging: First, in order to ensure that the new car reaches the standard when it is delivered to the user, the actual charged power will be higher than the marked power.
secondly, due to the discharge depth, charging current, and different battery management strategies, the actual charged power will vary, and more power may be charged.
Of course, you don’t have to have a deep understanding of the principle.
It can be simply understood as: under relaxed charging and discharging conditions, the amount of electricity that can be charged and discharged can be more than the marked amount, and there will be no extra cost.
Concerns about more electricity bills.
At the same time, the energy consumption displayed on the Xiaomi SU7 car terminal is the actual energy consumption, which has nothing to do with the charged power and the marked power, and there is no reverse false mark.
