Ladewärme
Ladewärme, a German term, translates to "charging heat" or "charge heat." It refers to the heat generated as a byproduct of the charging process in electrical devices, particularly batteries. This phenomenon is a result of the internal resistance within the battery and the electrochemical reactions occurring during charging. As electrical current flows through the battery, some of the energy is converted into heat due to this resistance, following Joule's law.
The amount of Ladewärme produced depends on several factors, including the battery's capacity, the charging rate
