7.7 Limon™ BMS Software Integration Settings

Integration settings connect the battery management system to a digital charger over CAN bus. The BMS detects the charger, then sends charge requests with the target voltage and a charge current that follows the battery's state of charge and temperature.

Danger

Always double check your values before saving all settings.

Table.7.7.2: Charging Current Table Bands

SoC band (%)	Temperature bands (°C)
0–10, 11–20, 21–80, 81–90, 91–95, 96–100	≤ 0, 1–10, 11–50, 51–60, > 60

Info

Each table cell is the charge current, in amperes, that the BMS requests when both the SoC and the temperature fall into that cell's bands.
