Why does the electric car display battery heating during charging?

[FaithDella]

The reasons for the electric car displaying battery heating during charging are as follows: Using an incompatible charger: Using a charger that does not match the battery can lead to abnormal charging and cause heating. Most households have one or more electric vehicles, and many families own different brands of electric vehicles with naturally different chargers. However, chargers are often mixed in use, which can cause the mobile power source to generate heat during charging, leading to battery heating. Prolonged battery usage: Batteries that have been used for too long may experience internal aging or short circuits, which can also cause heating. As the battery usage increases, water molecules within the battery, including those involved in discharge and charge, gradually deplete, resulting in heat generation during electrochemical reactions.
