What is low temperature battery?
Low temperature battery adopts special process and special materials. It has good charging and discharging performance under low temperature. It can be used at -40℃~60℃ and the discharging capacity of 0.2C at -40℃ is over 80% of initial capacity, so it is suitable for subzero temperature.
What is the operating temperature of the battery pack?
The normal operating temperature of the battery pack was specified as 50 °C. The vehicle was charged to 95 percent state of charge prior to the test, resulting in an initial voltage of 393 V. The starting temperature of the battery pack was 20 °C according to the battery management system.
Can grepow LiPo batteries be used in low temperature environments?
Grepow's LiPo batteries can be made to operate in environments with low-temperatures of -50℃ to 50℃. Under low-temperatures, the batteries can achieve a lower internal resistance and, thus, a high discharge rate.
What temperature should a battery pack be stored in?
Extreme temperature are not good for battery packs, and extreme heat is the worst. Temperatures in excess of around 80 degrees Fahrenheit will degrade a battery, with temperatures above 100 or 120 degrees Fahrenheit causing rapid damage. For that reason, it’s best to store batteries in a garage that remains relatively cool during the summer.
What is a grepow LiPo battery?
Custom ultra-low temperature batteries, with up to -50℃ discharge and -20℃ charging, high discharge efficiency, widely used in fields that require low-temperature, such as military , subsea, medical, aerospace, and polar regions. Grepow's LiPo batteries can be made to operate in environments with low-temperatures of -50℃ to 50℃.
What are grepow batteries?
Compared with traditional Lithium Polymer batteries, Grepow's batteries have broken through the discharge temperature limits of -20℃ to 60℃. Grepow's Low-Temperature LiPo batteries with special formula, can allow -20℃ charging with 0.2C current, without any external heating equipment.
