With the decrease of temperature, constant-current charge time and charge capacity decrease rapidly, while constant-voltage charge time and charge capacity increase, while total charge capacity decreases. When charging a battery at the same current, the time taken to charge the same capacity increases.
The relationship between charging cycles and temperature is crucial. Higher temperatures generally accelerate chemical reactions within the battery, impacting its ability to retain a charge over multiple cycles. This is particularly relevant for lithium-ion batteries, where excessive heat can contribute to capacity degradation and shorter lifespan.
Temperature is an important factor affecting the performance of lithium-ion batteries, so it is a key element in the research of battery thermal characteristics and thermal management to clarify the influence of temperature on battery charge and discharge performance.
It can be seen from Figs. 2.14, 2.15 and 2.16 that the charge performance of the battery decreases significantly at low temperature. Battery charging at low temperature has the following two characteristics: When the charging current is the same, the charging voltage increases with the decrease of temperature.
Impacts of battery temperatures on model parameters are experimentally identified. Number of charging stages and the associated transition conditions are adaptive. A trade-off between charging time and battery aging at low temperatures is achieved. Accumulative performances of existing charging methods are comparatively studied.
As rechargeable batteries, lithium-ion batteries serve as power sources in various application systems. Temperature, as a critical factor, significantly impacts on the performance of lithium-ion batteries and also limits the application of lithium-ion batteries. Moreover, different temperature conditions result in different adverse effects.
