Heating function description

Heating film

• 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≥ 15 ℃ to stop heating. b. When the temperature is ≥0℃, it can be charged without heating.

Display

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.
