6 FAQs about [New energy battery temperature 37]

What is the optimal operating temperature for a battery?

The optimal operating temperature range for these power batteries was found to be between 25–40 °C, and the ideal temperature distribution between batteries in the battery pack should be below 5 °C . Sato pointed out that when the battery temperature is higher than 50 °C, the charging speed, efficiency, and lifespan are reduced.

Can a temperature-rise model predict battery temperature during self-heating at low temperature?

A temperature-rise model considering the dynamic fluctuation in battery temperature and SOC is proposed, and it is possible to predict the battery temperature during the progress of battery self-heating at low temperature.

What is the best temperature to heat a battery?

The SP heating at 90 W demonstrates the best performance, such as an acceptable heating time of 632 s and the second lowest temperature difference of 3.55 °C. The aerogel improves the discharge efficiency of the battery at low temperature and high discharge current.

What is the average temperature of a battery pack?

After heating the bottom of the battery pack with PTC material for 3 hours, the average temperature of the external cells was 2.57°C, while the temperatures of the internal cells were －2.63 and －2.09°C.

What temperature can a battery module preheat?

It could preheat the whole battery module to an operating temperature above 0°C within a short period in a very low-temperature environment (–40°C). Based on the volume average temperature, the preheating rate reached 6.7 °C/min with low energy consumption.

What happens if a battery temperature distribution is uneven?

Uneven temperature distribution will result in uneven current and SOC distribution, which in turn leads to the fading of batteries electrochemical properties, furtherly the local accelerated aging. To this end, the design of heating strategy needs to consider the uniformity of battery temperature distribution.
