Testing with Monitor
The monitor will be tested for “ON” state for 30 mins to determine if the module is sufficient and stable (without cooling and ~21°C)
Time (mins) | Voltage (V) | Current (A) | Temperature (°C) |
|---|---|---|---|
0 | 18.385 | 1.04 | 24°C |
10 | 18.385 | 1.08 | 42°C |
20 | 18.385 | 1.08 | 39°C |
30 | 18.385 | 1.08 | 41°C |
Thermal Consideration
To determine the optimal thermal cooling under the car’s condition, the ambient temperature of 40°C was selected. Calculations are as follows:
