Temperature limitation

The BMS has implemented temperature limitations for the battery and the BMS itself.

info

• Before continuing, make sure, that all temperature sensor readings are correct and configured.
• All mentioned variables are located in folder /driver/temp/.

More about protection and limitation

Protection

The BMS ports are turned off when any temperature sensor reading is above its max value (or under min). To turn the ports back on, the temperature must be below the max value and the user must switch back on the BMS.

If the ports are turned off due to the temperature limitation, the BMS will enter PROTECT state.

Limitation

For each temperature sensor, you can configure the limitation. For the build-in temperature sensors, you can not configure the max parameter.

Parameter	Description
max	Maximum temperature for the sensor. If the sensor reading is above this value BMS enter PROTECT state.
marginMax	Area with no power.
decMax	Area with reduced power.
marginMin	Area with no power.
decMin	Area with reduced power.
min	Minimum temperature for the sensor. If the sensor reading is below this value BMS enter PROTECT state.

tip

• First, configure the max parameter, after that tune the limitation parameters
• The limitation can be configured even for sensors with ohm reading. Only the limitation parameters will be in ohms too.
