Produktinformationen "Application Brief 5992-2488EN | Temperature Profiling of Battery Charge and Discharge"
Application Note :: How to Select Test Instrumentation for Temperature Profiling of Battery Charge and Discharge.
Charge and discharge currents increase the temperature of the batteries and temperature directly affects the lifespan and storage capacity of batteries. Batteries tend to be efficient and provide a normal life span at room temperatures. When batteries are subjected to cold temperatures, their capacity is greatly reduced and as temperatures increase above room temperature, their life span is reduced. At extreme temperatures, batteries can break down in several stages; leakage, smoke, fire and explosion. Manufacturers often perform abuse tests to determine the temperatures for each of the stages of breakdown.
The increased adoption of consumer mobile devices has made measurement of heat relevant, particularly for when batteries charge and discharge. The rule of thumb for electronic devices is that for every 10°C rise in temperature, the average reliability of an electronic device decreases by 50%. Or, if we can lower the temperature by 10°C, we'll double the reliability. In other words, we can improve the expected meantime between failures ratings (MTBF) by two times, if the operating temperature is lowered 10°C.
This application brief will help you select test instrumentation to set up and make accurate battery charge and discharge temperature measurements so that you can make the appropriate capacity or life span trade-off, and improve the reliability of your product or device.
