What's the problem with not being able to charge iPad?

1. iPad cannot be charged:

Multiple possible failure points: ① charger failure, ② battery failure, ③ iPad2 software failure, ④ power supply failure.

①According to the description, the rear of the charger still works normally, indicating that there is no problem with the charger;

②Battery failure, the life of the battery may approach. The theoretical charge and discharge life of lithium batteries is 2000 times, however, overcharging and overdischarging will affect the battery life, after the battery life is over, it will not cannot be loaded. According to the description, the battery fault is eliminated.

③iPad2 software fault, there is usually a charger inside. The management software detects the charging capacity (current, voltage), battery temperature, etc. in real time. If there is a problem with the software, it. wrongly believes that the bbattery is full and charging cannot continue. Generally, software crashes can be restarted or self-healed after a power outage, which is more in line with your problem description, so this possibility is relatively high.

④ Power failure. The first possibility is poor socket contact and false power supply; the second possibility is that the supply voltage exceeds the rated operating range of the charging adapter and the charger does not work. This possibility can also be excluded based on the description.

In summary, the third situation is very likely.

The design and manufacturing principles of specific products are different. In the future, it is recommended to consult the manufacturer directly for technical solutions to such problems.

Also, if the iPad cannot be charged, it may be becauseIts battery has protection against low temperatures. Generally, lithium-ion batteries are equipped with low temperature protection because when charging at low temperatures, the lithium metal present in the battery is deposited, leading to an internal short circuit in the battery.

So in winter, when the iPad cannot be charged under normal circumstances, the main thing is to find a warm environment for it. You can also try the following methods.

1. Charge in an air-conditioned room.

2. Cover yourself with the duvet and recharge your batteries in bed.

3. When charging the iPad 2, it will give off a certain amount of heat, which is helpful for charging.

4. When charging fails, you can use a hair dryer to blow hot air on the back of iPad 2 for 1-2 minutes, then it can be charged.

5. You can put it on the radiator andand cook.

6. Place it on a hand warmer to warm it up. Don't forget to put a quilt or something between the hand warmers.

7. Place the iPad2 under the duvet and turn on the electric blanket to charge it.

There are many reasons why the iPad cannot be charged, and you should carefully consider each possibility.

Regardless of the brand of electric vehicle batteries, most of them are lead-acid batteries. They need to be recharged after traveling several kilometers and half the time. It is best not to let the battery be fully charged. discharged then recharged. There is only a small amount of lithium. Batteries should be recharged after being discharged.

The required charging capacity of the battery should be 110-120% of the discharge capacity. is closely related to battery life. Suppose that thecharging capacity is 120% of the discharge capacity. The battery has a lifespan of 1,200 times (4 years). It canThe estimated battery life is: 1200 times × 120/150 = 960 times (3·2 years).
