Function description
5.1 Heating function description
A. The heating function adopts BMS to control the heating film, and the
protection plate can start the heating mode by collecting the temperature and
current;
B. Heating film ：The main cross-sectional structure of the diaphragm includes
polyimide film (0.08), heating element (0.05), and polyimide in order Membrane
(0.08), double-sided tape (0.11) with a total thickness of 0.36±0.1MM, strong
adhesion and no cracking after long-term use;
Working mode: Charging working mode: after the charging device is connected to
the battery, the protection board performs current detection. If the current
is less than 5A, the battery can be charged; if the current is more than 5A,
the protection board needs to detect the temperature: a, when the temperature
is less than 0 ℃, turn on the heating film, the temperature When heated to
above 0 ℃, the battery can be recharged, continue to heat until the
temperature≥ 10 ℃ to stop heating. b. When the temperature is ≥0℃, it can be
charged without heating.

5.3. CAN
The BMS has the function of battery pack upload to CAN communication, 500K
baud rate CAN communication interface adopts 8 P8C network interface. You can
communicate with the Victron Cerbo GX box.
