Xiaomi SU7 Updates and Explanations on Battery, Charging, and More

TapTechNews May 23rd news, Xiaomi Auto officially released Xiaomi SU7 Q&A for Netizens (Episode 42) today, answering some questions that users cared about, such as the progress of production capacity and delivery improvement, and that it took 87.86 kWh to fully charge a 73.6 kWh battery.

TapTechNews attaches the full text as follows:

01. How is the current progress of Xiaomi SU7's production capacity and delivery improvement?

After a series of efforts, our current production capacity expansion and delivery speed-up progress are very smooth.

In June, the Xiaomi Auto factory will operate in two shifts, and we will ensure that more than 10,000 units are delivered monthly in June.

We will ensure the delivery of more than 100,000 units throughout the year, and at the same time, we will further strive for the delivery of 120,000 units.

02. Some media tested that it took 87.86 kWh to fully charge a 73.6 kWh battery for Xiaomi SU7, why is this?

To put it simply: this is not reverse under-rating, nor will it cost more electricity, but the true reflection of the real charging amount and discharging amount.

To explain this problem clearly, we must first introduce a concept: that is, the real electricity quantity (including the charging amount and discharging amount) is different from the battery capacity marked in the product announcement. In fact, the marked capacity is tested, not a fixed value.

In the industry, 1C or 1/3C is generally used to mark the battery capacity. This 1C or 1/3C is the discharge rate, which refers to how fast (at what rate) to discharge:

1C means that a fully charged battery is discharged at a fixed current until it is depleted in 1 hour.

1/3C means that a fully charged battery is discharged at a fixed current until it is depleted in 3 hours.

In accordance with the requirements of regulations, when Xiaomi SU7 was announced, it was declared according to the 1C standard, so the battery capacity of the standard version of Xiaomi SU7 is 73.6 kWh. According to the 1/3C discharge, the standard version of Xiaomi SU7 can discharge 76.8 kWh. It can be seen that for the same battery, the discharged electricity quantity is different according to different discharge rates. At the same time, in daily working conditions, the discharge rate is lower, the battery can discharge more electricity, and can also run more miles.

As for charging, there are more influencing factors: first, to ensure that the electricity is up to standard when the new car is delivered to the user, the actual charged electricity will be higher than the marked electricity; second, because of the different discharge depth, the charging current magnitude, and the battery management strategy, the actual charged electricity will also be different, and it is possible to charge more electricity.

Of course, everyone doesn't have to understand the principles in depth. It can be simply understood that under mild charging and discharging conditions, the amount of electricity that can be charged and discharged is more than the marked electricity, and there is no worry about additional cost of more electricity. At the same time, the energy consumption displayed on the Xiaomi SU7 vehicle side is the actual energy consumption, which has nothing to do with the charged electricity and the marked electricity, and there is no situation of reverse under-rating.

03. The wireless charging of Xiaomi SU7 mobile phone supports up to 50W at most, why does it sometimes feel not that fast?

The Xiaomi SU7 is standardly equipped with a mobile phone wireless charging board with a maximum charging power of 50W, but the actual mobile phone charging power will vary due to different mobile phone brands/models and different mobile phone states:

The mobile phone wireless charging board of Xiaomi SU7 supports Xiaomi's private protocol and Qi protocol, and the wireless charging power of different mobile phones is different

The wireless charging of Xiaomi series mobile phones adopts Xiaomi's private protocol and can obtain the maximum 50W charging power on the mobile phone wireless charging board of Xiaomi SU7. But among them, Xiaomi 13Pro can obtain the maximum 30W wireless charging power on the mobile phone wireless charging board of Xiaomi SU7 because it adopts a small-sense value receiving coil with low heat and high efficiency.

The wireless charging of other Android mobile phones adopts the Qi protocol, so it can obtain the maximum 15W wireless charging power on the mobile phone wireless charging board of Xiaomi SU7.

Because Apple mobile phones adopt a specific frequency band of the Qi protocol, it can obtain the maximum 7.5W wireless charging power on the mobile phone wireless charging board of Xiaomi SU7.

If the mobile phone state is different, the wireless charging power will also be different

If the mobile phone is currently in a high-power operation state, the mobile phone wireless charging power will actively reduce for thermal protection.

If the current mobile phone battery is relatively full, the mobile phone wireless charging power will also actively reduce for battery protection.

In addition, if the mobile phone is placed relatively biased, it may also lead to a reduction in wireless charging power. You can try to adjust the mobile phone position to obtain the maximum wireless charging power.

04. When the air conditioning air volume is adjusted to a large value, the media volume will also automatically increase. Is it normal?

Normal, this is the sound automatic compensation function. When this function is enabled, the sound will compensate according to the surrounding environmental noise to provide a better auditory experience. You can enable or disable it according to your own preference in Settings - Sound.

05. The screen shows that when the main driver user leaves the car, the mobile phone mirroring function is disabled. Can this be closed?

In order to protect the privacy of the main driver user when the user uses the wonderful desktop function, when the main driver user gets out of the car or opens the door, the wonderful desktop function entrance will be temporarily closed. At this time, the mobile phone icon at the bottom of the central control screen is grayed out and cannot be clicked and used for the time being. This function is enabled by default and cannot be closed.
