1. Deep discharge has a great impact on the lifespan of lithium batteries. Combination batteries typically have a cycle capacity of 800 times > 80% of the original capacity.

2. Be careful when connecting supercapacitors in parallel. Supercapacitors can handle large instantaneous currents, but the instantaneous current to charge them is also very important if you don't solve the battery problem after the supercapacitors are finished. discharged, when charging, the use of supercapacitors does not reduce the high-current discharge charge on the battery, but increases the instantaneous discharge depth of the battery.

3. The lithium battery charging method is constant current and constant voltage. . . Ni-MH batteries are pulse charged and lead acid batteries are float charged. .

The lithium battery in electric vehiclestriques is best loaded when there is about 20% remaining. Do not fully charge it after using it. You can recharge it when there is about 20% left. do not charge it completely. Above 80 is almost enough.

The lifespan of lithium batteries is limited, that is, the number of times they can be charged is limited. Lithium batteries can generally be charged and discharged about 500 times. Do not start charging until they are completely empty. , and you also don't charge it until it's fully charged to 100%. The lifespan of lithium battery is about 500 charges and discharges, which does not refer to the number of charges, but the number of charge and discharge cycles.

To put it simply, you start charging when there is 50% left after the first use. After charging, you always start charging with 50% remaining. Thatcan only be counted as one charge and discharge cycle (. this explanation is of course not valid. This means that it can be used indefinitely if not used every time. We can only say the cycle is extended and the duration of use is longer).

Detailed information:

Battery life

I believe that most Some consumers have heard that the lifespan of a lithium battery is “500 times longer”. In order to extend battery life, it is only charged when the battery is completely exhausted. Does it really extend battery life? the answer is negative. The lifespan of a lithium battery is "500 times", which does not refer to the number of charges, but to one cycle of charging and discharging.

A charge cycle means that all of the battery's energy is used pleine empty, then loaded from empty to full. This is not the same as a single charge. For example, a lithium battery only uses half its power the first day, then it is fully charged. If it is still the same the next day, i.e. if you charge it half and charge it twice in total, this can only be counted as one charging cycle and not two.

Therefore, multiple charges may typically be required to complete a cycle. Each time a charge cycle is completed, the battery capacity decreases a little. However, this power reduction is very small. High quality batteries retain 80% of their original capacity after being charged several times. Many lithium-ion powered products are still in use after two or three years. Of course, lithium batteries still need to be replaced once their lifespan is reached.

What the on calls 500 times means that the manufacturer has achieved approximately 625 times of recharge at a constant depth of discharge (e.g. 80%). times, reaching 500 charge cycles.

(80%*625=500) (ignoring factors such as lithium battery capacity reduction)

Due to various influences in real life, especially the depth of discharge during charging is not constant, so "500 charging cycles" can only be used as a reference for battery life.
