  As a commonly used energy storage device, batteries are widely used in electronic products, transportation and energy storage. However, because the working status of the battery is closely related to the temperature, the temperature is too high or too low, which will cause the battery to decline in the capacity, power, life and other aspects of the battery, so the battery must be controlled.

  Usually, the working status of the battery changes with temperature. As the temperature rises, the chemical effects in the electrolytes are accelerated, so that the amount of charge in the electrolytes and the migration of ions will be accelerated, thereby increasing the capacity of the electrolytic groove and increasing the output power. However, if the temperature of the battery is too high, the battery is vaporized and expanded, causing problems such as electrolyte leakage and battery damage. At low temperature, as the chemical response speed of the battery becomes slower, the resistance generated is larger and the charge migration speed becomes slower, which makes the battery capacity smaller and the output power becomes smaller. In addition, if the temperature is too low, the battery will freeze and damage.

  Therefore, in order to ensure the working status and service life of the battery, it must be managed by temperature. Its control method can be divided into two types: internal and external. Add heat sinks to the battery to enhance the thermal insulation capacity of the battery shell, thereby achieving temperature control inside the battery. If the external temperature is controlled, the temperature sensor can be used, or the battery heater can be used.
