7 inch LED Controller Battery Safety Testing -70 °C Low Temperature Test Chamber
1. Explore Temperature Chambers by Type:
Environmental testing of automobiles requires additional consideration of the facility where the chamber will be installed, and its planned use. Test methods for vehicles can include additional conditions besides temperature and humidity in an attempt to simulate real-world conditions.
As we come to rely more upon batteries, reliability and safety become a concern in hot and cold conditions. Through temperature testing with KOMEG chambers, the batteries’ ability to withstand environmental extremes and stress can be identified safely.
2. High temperature limits of test chambers
There are many types of test chambers, but they all high and low temperature limits. Let's take a look at the typical high temperatures thresholds and why they exist.
Test chambers usually have wire heaters made of a material called Nichrome. By placing successive loops of heater wire, a greater amount of heat that is generated. The result looks a lot like the inside of a toaster. Fans circulate the air past the heaters, so the samples in the chamber are not exposed to radiant heat. It is very easy to add heaters and increase the speed and / or high limit of a chamber.
KOMEG chambers typically have a high temperature limits under 200°C. Here is a break-down of why a chamber's high temperature limit exists:
150°C: There are two reasons we may limit a chamber to 150°C. First, there may be a limitation of the materials used inside the chamber. Secondly, for extremely fast chambers, we may limit the high temperature to avoid problems with accidentally tripping overheat protection devices.
170-180°C: Most models stop at this temperature range. There is a risk of burning the oil inside the refrigeration's cooling coil.
