The impact of temperature on the laptop battery
|
In mobile use, the battery decided laptop life, due to the lithium-ion battery with a laptop in a non-normal temperatures, the temperature is too high or too low will bring a variety of issues, then the laptop battery temperature can affect it? The first ,0-40 is the most reasonable working environment Laptops in use, humidity, static electricity, temperature, and so have an impact on it, but the lithium-ion HP Pavilion DV7 Battery is most sensitive to temperature, the temperature is too high or too low, the battery will bring negative impact to varying degrees, usually, the limits of lithium-ion battery ambient temperature -20 ~ 60 , while the 0 ~ 40 is the most reasonable working environment, but to play the potential of laptop battery performance, 20 or so is the best use of the environment. Second, -25 the following will affect the battery life Although the Dell Studio XPS 1340 Battery in -20 environment allows to use, but this will affect the battery charge and discharge performance of very large, usually, the lower the ambient temperature, the battery inside the lower the activity of active material, electrolyte resistance and viscosity The higher the ion diffusion more difficult, not easy to charge and discharge the battery. For example, when the ambient temperature is below zero, the battery charge and discharge efficiency will be greatly reduced, so the charge rate will be very slow, full time after power supply is only about 60% of the original, when the ambient temperature falls below the minimum temperature limit (for example - 25 ), the SONY VGP-BPS13 Battery electrode reaction rate is very low, even from the freezing point of the electrolyte, the battery performance may be only 10%, seriously affecting the battery life. Third, 60 above may explode As in the case with the low temperature, if the laptop battery in high temperature environment, which will affect the battery charge and discharge efficiency, but more serious damage to the battery, such as use of poor quality, or charger, charging time is too long, making the heat a larger battery, when the charge temperature exceeds the maximum limit temperature, which will destroy the chemical balance within the battery, resulting in performance degradation of battery materials, battery life decreased. Similarly, the HP DV9000 Battery during the discharge time, that is, when we use the notebook as an internal short-circuit the battery or the battery design flaw, if the working temperature exceeds the maximum limits of battery capacity decreased, the life loss, but also a serious situation to explode, burning and other accidents. |
