Description

The test specimen is inserted into the test chamber and connected to the test medium circuit. To simulate battery operation in an electric vehicle, a low voltage (0 to 20VDC/5A) or high voltage (0 to 600VDC/150A) power supply is available. The test medium (water-glycol mixture or pure glycol, for example Glysantin® G40, G44, G48) circulates at a freely controllable temperature of -35 to +100 degrees Celsius and a volume flow of 3 to 30 l/min. Optionally, the test can also be carried out in an air-conditioning cabinet at -40 to +140 degrees Celsius to simulate changing ambient temperatures. A meaningful long-term test usually takes 20 days. The temperature and volumetric flow of the test medium as well as the ambient temperature will vary around the clock according to the programmed test cycles if the test takes place in the climatic chamber. The temperature of the test medium at the inlet and outlet of the test specimen and the ambient temperature are continuously measured. The flow, pressure and pressure drop as well as current and voltage in the high and low voltage range are also documented. The focus is on the thermal and electrical performance of the heating and cooling unit under varying environmental conditions. Performance: Test medium: water-glycol mixture or pure glycol Medium temperature: -35 ° C to +100 ° C Cooling capacity: 15 kW at -35°C Heating power electrical.: 25 kW Ambient temperature control: -40 ° C to + 140 ° C (optional) Flow rate control: 3 to 30 l/min Battery simulation: High Voltage: 0 to 600VDC/150A Low Voltage: 0 to 20VDC/5A
