Comparison of charging and discharging efficiency between lithium batteries and lead-acid batteries

When a lithium-ion battery is discharged, its operating voltage always changes at over time. The operating voltage is used. on the ordinate, and the discharge time, or capacity, or state of charge (SOC), or depth of charge and discharge (DOD) is used on the abscissa. The curve drawn is called the charge-discharge curve.

According to the charge and discharge curve, it can be judged whether the battery performance is stable and the maximum current allowed by the battery when working stably. The following two graphs are the charge and discharge curves of lead-acid batteries and lithium batteries respectively. From the curve graphs, we can intuitively obtain the charging and discharging efficiency of both. You can judge which battery is more efficient.

For the same fully charged lead-acid battery, at the same temperature and using different discharge current rates, the discharge output characteristics are very different, resulting in unstable power.

Lead-acid battery charge and discharge curve

For the same fully discharged lithium battery, at the same temperature and using different discharge current rates, the characteristics of discharge output are very stable. Compared with lead-acid batteries, the charging and discharging efficiency is much higher.

Lithium battery charge and discharge curve

There are many types of lithium batteries. The maximum discharge current of ordinary lithium batteries is 1C, the discharge current of high-rate lithium batteries is 4C, and the discharge current of electric batteries is 10~20C. C here refers to the capacity of the batterye, which means that the maximum discharge current of an ordinary 1000 mAh lithium battery is 1000 mA. The maximum discharge and charge of the 1000 mAh battery can reach 10 ~ 20 A. For example, our mobile phones use ordinary lithium batteries, while some model aircraft, electric cars, electric drills, etc. use ordinary lithium batteries. use lithium batteries, also known as lithium iron batteries. The voltage of electric batteries is lower than that of ordinary lithium batteries.

For an engine like yours, it is best to use a power battery of the capacity you consider appropriate. The power supply battery current of 20 Ah/24 V is sufficient.

The maximum instantaneous discharge current depends on the internal resistance of the battery and the protection plate. The short circuit current of ordinary 1000 mAh lithium battery is also higher than10 A, but for battery safety reasons. , the protection plate is limited to about 3A. Generally, the internal resistance of power batteries is very low.
