App

MiHome and Segway's Ninebot (which is now a subsidiary of Xiaomi).

Advantages of MiHome: allows you to see more parameters such as the charge of each group of cells in the battery.

Advantages of Ninebot: simpler and more intuitive.

Negative: the geolocation request for each connection for both apps.

Does my Xiaomi m365 electric scooter BMS have only one or two Z-fuses?

From the serial number of the scooter, look at the first 5 digits:

If the number is less than 35000, you are in V1 with 1 fuse.

If the number is greater than 35000, you are in V2 with 2 fuses.

If the number is exactly 35000, it is necessary to check visually on the electronic card.

Where is the serial number of the scooter?

From the official Mihome application, look at the serial number "Vehicle serial number" or directly behind the scooter stand. It is a code with 5 digits, the character / and 8 digits.

How to differentiate between an M365 and a Youth (M187)?

From the serial number of the scooter, look at the first 5 digits:

13678 = M365, White color China version, battery >March 2017.

13679 = M365, Black color, China version.

16057 = M187, Youth edition model, battery >March 2017.

16133 = M365, Colour black European version.

16132 = M365, Colour white European version, battery >March 2017.

Where is the serial number of the battery?

From the official Mihome application, look at the battery serial number "Battery serial number" which is a 13-digit/character code.

Battery: Do I have reinforced welds?

Several solutions, the battery number begins with:

"3JBG", first version.

"3JCG", second version, with reinforced welds on the batteries (V June 2017).

"3JEE", third version, with reinforced soldering on the batteries (V August 2017).

Versions after August 2017 have foam in the battery cover.

List of error codes and audible signals with beep:

Transposition of error codes in beeps: 1st digit = number of long beeps, 2nd digit = number of short beeps.

Transposition of the error codes in green led flash (on the ESC controller): 1st digit = number of long flashes, 2nd digit = number of short flashes.

10 - Bluetooth module communication error.

11, 12, 13, 13, 28, 29 - Calibration error of current sensors or power supply of MOSFET transistors.

14, 15 - Problem related to the accelerator or brake.

18 - Error related to the Hall sensor (in the motor).

21 - Battery communication error (BMS).

22, 23 - BMS serial number error.

24 - Input voltage error.

27, 39 - Problem with the serial number of the speed controller (ESC) or not activated.

35

36 - Battery overheating or heat sensor error.

40 - Overheating of the speed controller (ESC).
