6 FAQs about [Maximum battery heating current]

What is the maximum battery temperature variation?

For the battery SOC range between 20 and 90%, the maximum battery temperature variation is about 1 °C. The battery maximum mean temperature is computed for a fixed value of charge current in the range of 10 A–60 A using the developed model. Figure 14 illustrates the obtained results in quasi-stationary regime for Rcurrent variable until 6.

What is the current heating principle of a battery?

The current heating principle is that the current flows through the battery to generate heat through internal resistance . The heat generation of batteries includes reversible heat and irreversible heat . Reversible heat is entropic heat originating from the reversible entropy change during electrochemical reactions.

What temperature should a battery be heated at?

Most studies set the initial temperature at −20 °C and rarely considered the impact of different initial temperatures on the heating effect. In addition, the optimal working temperature of the battery is around room temperature, i.e., 20 °C. However, the current heating targets in most studies range from 0 to 10 °C.

What is the heating rate of a battery?

The heating rate decreases from 1.1 to 0.34 °C/min when the battery temperature exceeds 0 °C according to the experimental results in ref. . Most studies set the initial temperature at −20 °C and rarely considered the impact of different initial temperatures on the heating effect.
