Temperature compensation method and device, terminal equipment and readable storage medium

The embodiment of the invention provides a temperature compensation method and device, terminal equipment and a readable storage medium, and is applied to the technical field of terminals. According to the method, nonlinear compensation is carried out on a first temperature value of the battery protection board through a target compensation parameter searched from a compensation relation comparison table to obtain a second temperature value, and when a difference value between the second temperature value and a third temperature value is greater than a temperature change threshold value, summation is carried out on the third temperature value and the temperature change threshold value to obtain a second temperature value. When the difference value between the third temperature value and the second temperature value is larger than the temperature change threshold value, the difference value between the third temperature value and the temperature change threshold value is calculated, and a target temperature va
