What Causes Severe Overheating in Cars?

[MatteoAnn]

Severe overheating in cars can be attributed to the following reasons: Battery overheating: The efficiency of converting electrical energy into chemical energy is 50%, with most of the remaining 50% released as heat, causing the battery to overheat. Batteries have internal resistance, which increases as the charge decreases. According to P=I×I×R, the power consumed by internal resistance is also converted into heat, leading to battery overheating. Continuous charging: After the battery is fully charged, continued charging means that electrical energy is almost no longer converted into chemical energy but almost entirely into heat, causing the battery to overheat. Additional information: Precautions: If severe battery overheating occurs, it indicates self-discharge and overheating, suggesting an internal short circuit in the battery's plates, meaning the battery has reached its end-of-life limit.
