The project involves the thermal analysis of the Lina battery. Due to the high operating temperature, it is necessary to apply insulation to the battery model. Various types of insulation were applied at different thicknesses to give an idea of which performs the most effectively. Another part of the project involved applying heaters to the model; this is to maintain the high operating temperature when it is out of operation. An additional consideration that was taken into account is when the battery is running at high power. Therefore it is important to find a balance between keeping the battery hot and avoiding over-heating. The final part of the project involves bringing together battery packs into a system that would be suitable for an electric vehicle.
