6 FAQs about [Battery pack charging experiment]

How long does a battery pack take to charge?

The charging time of the battery pack was calculated to be about 4 h according to Equation (16), and the preheating target temperature was calculated to be 16 °C according to Equation (13). Fig. 8 (b) shows the change of the average temperature in the battery pack.

Does heated battery pack improve charge performance?

The charge performance of the battery pack heated is improved significantly by heating. After the battery pack at −40 °C is heated for 15 min with 240 W power, its charging performance is close to the charging performance of the unheated cell at 0 °C.

What is the heating power of the experimental battery pack?

Since the experimental battery pack is one-tenth of the number of battery modules in the battery pack, we also use one-tenth of the estimated heating power of the battery pack, which is 30 W. We power the heating plate with a tracking power supply and adjust its output to make the total heating power of the heating plate 30 W.

What is battery pack low temperature charging preheating strategy?

Battery pack low-temperature charging preheating strategy The required charging time of the battery pack depends on its state of charge before charging, the ambient temperature during charging, and the insulation effect of the battery pack.

How to calculate average temperature of battery pack during charging process?

To ensure that the average temperature of battery pack is above 0 °C during whole charging process, we take cooling time as charging time tc, and average temperature of battery at end of charging as 0 °C. Substituting ( tc ,0) into formula (10) can obtain calculation formula of constant a: (11) a = − T 0 e A k m C p t c
