Function test of energy efficiency of the battery during operation

In many EVs, the heating and cooling systems drain the battery and negatively affect the vehicle’s range. Comparing test results before and after a load change test on a function test bench can show how power consumption and performance change over the vehicle’s service life. The test object is connected to the power supply (low voltage 0-20VDC/5A) or high voltage (0-600VDC/150A) and the test media circuit. The test medium is circulated at a temperature of between -35°C to +100°C (-31°F to +212°F) and a flow rate of 1-50 l/min. The test can also be carried out in a climatic chamber at -40°C to +140°C (-40°F to +284°F) simulating changing ambient temperatures such as simulating ice-cold temperatures in Canada during Winter as well as dry heat around the Sahara desert.
