Battery Cooling Options

Forced Air Cooling

There are many battery cooling options, which is better or best depends on the cell selection and application. There is no right and wrong. However, let’s look at them and at a first attempt list of advantages and disadvantages. Note: all of the images show a section through cylindrical cells, but each of these cooling … Read more

What happens when batteries are abused?

Billy Wu when batteries go wrong

Lithium-ion batteries are an essential component in electric vehicles, however their safety remains a key challenge. This video explores the science behind what happens when batteries are abused and when they fail. Mechanical abuse Electrical abuse Thermal abuse Starting from how a battery cell works, this presentation from Billy Wu at the Dyson School of … Read more

Specific Heat Capacity of Lithium Ion Cells

The specific heat capacity of lithium ion cells is a key parameter to understanding the thermal behaviour. From literature we see the specific heat capacity ranges between 800 and 1100 J/kg.K Heat capacity is a measurable physical quantity equal to the ratio of the heat added to an object to the resulting temperature change. Specific … Read more
