Monitoring Battery Temperature

Too low battery temperature will slow the charging rate while too high battery temperature will create a hazard. Maintaining the correct charging temperature range has the added benefit of increasing battery life expectancy.
Li-Ion batteries typically increase 5°C (9°F) in temperature during the 2-3 hours required for charging. This temperature rise is normal and due to the chemical reaction occurring during the charging cycle. To avoid hazard, the battery must not be allowed to increase more than 10°C (18°F) during charging.
The ambient temperature in the immediate environment of the battery contributes heavily to the temperature of the battery during the charging cycle. Heat created by the chemical reaction of charging acts to increase the initial temperature of the battery. The optimum Li-Ion battery temperature range during charging is quite narrow, between 10°C and 30°C (41°F to 86°F). Fast charging, while acceptable, requires that battery temperature not exceed 45°C (113°F). Charging above 45°C (113°F) will degrade battery performance.

Over Temperature Hazard

Over-temperature, whether due to over current, over voltage, high ambient temperature, or any combination of these, can lead to thermal runaway. This is a dangerous condition which can result in a battery fire or even a catastrophic explosion. To avoid thermal runaway, upper safe battery temperatures cannot be exceeded.
 

Temperature Sensor Selection

As a crucial component in Li-Ion battery charging, the selection of the correct battery temperature sensor is also crucial. Selection of a sensor should consider:

• Accuracy - Tight tolerances necessary for critical temperature measurements
• Reliability - Guaranteed specifications and stable characteristics over time
• Responsiveness - Low thermal time constant providing timely controller feedback
• Durability - Robust service life from quality components and precise manufacturing
