IT Home News on May 23, Xiaomi Auto officially released "Xiaomi SU7 Answers to Netizens' Questions (Episode 42)" today, which answers questions about the progress of production capacity and delivery improvement that some users are concerned about, and the 87.86 kWh of electricity charged by a full 73.6-degree battery.

The full text of the attachment is as follows:

01. What is the current progress of Xiaomi SU7 production capacity and delivery improvement?

As a result of a series of efforts, our capacity expansion and delivery acceleration are progressing very well.

In June, Xiaomi's auto factory will open two shifts, and we will ensure that more than 10,000 vehicles will be delivered in a single month in June.

We will ensure that more than 100,000 vehicles will be delivered throughout this year, and at the same time, we will further sprint to deliver 120,000 vehicles.

02. There is a media test, "Xiaomi SU7 costs 87.86 kWh of electricity when it is fully charged with a 73.6-degree battery", why is this? 

Let's talk about the conclusion first: This is not a "reverse false standard", and it will not cost more electricity, but a true reflection of the real charging and discharging amount.

To explain this, let's first introduce a concept: there is a difference between the actual "power" (including the amount of charge and discharge) and the battery level indicated in the product announcement. In fact, the amount of electricity labeled is tested, not a fixed value.

In the industry, 1C or 1/3C is commonly used to mark the battery level. This "1C" or "1/3C" is the "discharge rate", which refers to "how fast (several times the rate) to discharge":

1C is a fully charged battery, which is discharged at a fixed current and discharged for 1 hour until the power is lost

1/3C, that is, a fully charged battery, is discharged at a fixed current and discharged for 3 hours until the power is lost

In accordance with the requirements of the regulations, when the Xiaomi SU7 was announced, it was declared in accordance with the standard of 1C, so the battery capacity of the Xiaomi SU7 Standard Edition is 73.6 degrees. According to the 1/3C discharge, the Xiaomi SU7 Standard Edition can release 76.8 kWh. It can be seen that according to different discharge rates, the amount of power emitted by the same battery is different. At the same time, in daily working conditions, the discharge rate is lower, the battery can release more power, and can run more mileage.

Regarding charging, there are more influencing factors: first, in order to ensure that the power of the new car is delivered to the user, the actual charging power will be higher than the marked power; Secondly, due to the difference in the depth of discharge, the size of the charging current, and the battery management strategy, the actual amount of charge will also be different, and more power may be charged.

Of course, you don't have to understand the principle in depth, it can be simply understood as: under the condition of moderate charging and discharging, the amount of electricity that can be charged and discharged can be more than the marked electricity, and there will be no worries about spending more electricity. 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 charging power and the marked power, and there is no reverse false standard.

03. Xiaomi SU7 mobile phone wireless charging supports up to 50W, why does it sometimes feel not so fast?

The Xiaomi SU7 comes standard with a wireless charging pad with a maximum charging power of 50W, but the actual charging power of the phone will vary depending on the brand/model of the phone and the status of the phone:

The wireless charging pad of the Xiaomi SU7 supports the Xiaomi private protocol and the Qi protocol, and the wireless charging power of different mobile phones is different

The wireless charging of Xiaomi series phones adopts the Xiaomi private protocol, which can get a maximum charging power of 50W in the wireless charging pad of the mobile phone of the Xiaomi SU7. However, the Xiaomi 13 Pro uses a small inductance receiver coil with low heat generation and high efficiency, so it can get a maximum of 30W of wireless charging power on the mobile phone wireless charging pad of the Xiaomi SU7.

Other Android phones use the Qi protocol for wireless charging, so the wireless charging pad on the Xiaomi SU7 can get a maximum of 15W of wireless charging power.

Because the Apple phone uses the specific frequency band of the Qi protocol, the wireless charging pad of the Xiaomi SU7 can get a maximum of 7.5W of wireless charging power.

Depending on the status of the phone, the wireless charging power will also be different

The mobile phone is currently in a high-power operation state, and the wireless charging power of the mobile phone will be actively reduced for thermal protection.

When the current battery of the mobile phone is full, the wireless charging power of the mobile phone will also be actively reduced for battery protection.

In addition, if the phone is placed too far away, it may also cause the wireless charging power to decrease, so try adjusting the phone position to get the maximum wireless charging power.

04. When the air volume of the air conditioner is increased, the volume of the media will automatically increase, is it normal?

Normal, this is the automatic sound compensation function. When this feature is turned on, the sound compensates for ambient noise, providing a better listening experience. You can turn it on or off in "Settings" - "Sound" according to your preference.

05. The screen shows "When the main driver user leaves the car, disable the mobile phone mirroring function", can this be turned off?

In order to protect the privacy of the main driver when using the Magic Desktop feature, the entrance to the Magic Desktop feature will be temporarily closed when the driver gets out of the car or opens the door. At this time, the mobile phone icon at the bottom of the central control screen is grayed out and cannot be clicked for use temporarily. This feature is enabled by default and cannot be disabled.
