Test Heater Function
Test Specification
Turn on the heater with the power supply set to 1.5W power input. Measure and record the temperature of the heater every 30 seconds on its top surface. Once the temperature of the heater converges, record the power density.
Judge Criteria
The heater successfully heats up to convergence temperature

Test Set-Up
Test Set-Up
Assemble thermistors on the batteries' desired location with thermal epoxy
Follow epoxy datasheet to cure thermal epoxy.
Clean the battery saddle with isopropyl alcohol, dry with Kimwipes
Assemble heaters to the battery saddle with the heaters' backing adhesives.
Store the battery saddle assembly in a fridge set to 10 °C overnight.
Test Procedure
Test Procedure
Take out the battery assembly from the fridge.
Connect battery saddle assembly to controller.
Away from heat-sensitive parts, connect the heater to a power supply.
Record initial temperature of the heater, and turn on the power supply to 1.5W.
With a temperature probe, measure and record the heater's temperature every 30s until the heater's temperature converges.
If the heaters' current does not suggest that the heater is turned on, stop testing and inspect connection between the heater, thermistor, and controller.
Compare the thermal probe reading to the thermistors'.
If the thermistor does not report a temperature within 2°C of the thermal probe, stop testing and inspect thermistor mechanical and electrical connections.
Once heater reaches 20 °C, measure and record the heaters' current
If the heaters' current does not suggest that the heater is turned off, stop testing and inspect connection between the heater, thermistor, and controller.
Read temperature at the thermistor locations with a thermal probe, record the thermal probe read value
Compare the thermal probe reading to the thermistors'.
If the thermistor does not report a temperature within 2°C of the thermal probe, stop testing and inspect thermistor mechanical and electrical connections.
