How to use various lithium batteries in daily life,First, mobile phone lithium battery charging common sense
1,12-14 hours: The first generation of nickel-cadmium batteries need to be charged, generally recommended charging current 1/10c, such as 600mAh, then 1C is 600mA, 1/10c is 60mA. Therefore, it takes more than 10 hours to fully charge, which is good for nickel-cadmium batteries.
2. Knowledge of lithium-ion batteries: We only say capacity on the one hand. Measuring a lithium-ion battery has two detection methods: 1C charge, 0.2C; 0.2C charge, 0.2c put, no matter what charge system, it should be compained. Because the lithium ion battery has been different from previous nickel-cadmium batteries, the high-magnification charging of 1C can be accepted usually, and it must be accepted. And if a 600mAh battery is charged at 1C, it should be filled around 1 hour. If the mobile phone direct charge is designed such (many are 0.5c-0.8c), 12-14 hours is nonsense.
3, what is the 'activation'? The lithium-ion battery itself is 'live', if the design capacity is 600mAh, although I charge for 2 hours, then discharge, you can get a capacity of 600mAh, the capacity of the design can be reached, this Is there any problem? The technical supervision department implemented national standards, and the detection capacity was charged with 1C, then put, one capacity in 5 times reached the calculation. So normal use, normal charging, you can use it from the new battery, don't worry about '激 不'.
4. The battery is currently equipped with a lithium-ion battery in the mobile phone. The recent impression of our impression should be 3210 released in 1999, a nickel-hydrogen battery with a nickel-hydrogen battery, and a mobile phone that has not been found around us. .
5. According to GB / T18287 2000 national standard, when constant current charges to 4.2V, turn constant pressure, when the current falls to 0.01c, it is considered to be terminated. For example, the charger charging current is 0.5c, charge 600mAh battery, 2 hours, the charging current will drop to 6mAh, and it is considered to be filled. Why drops to 0.01C? Because it is already full, this is the reflection of the battery. For nickel-hydrogen electricity, national standards have also specified the indicators of high-magnification charge and discharge.
6, charge 14 hours is: Most of the mobile phone battery is a lithium battery, direct charge with the mobile phone, is over 2 hours, this step is the result of the cross-flow charging; the remaining time constant pressure charging, ie the flow charging , Make the battery battery more powerful, longer standby time.
Second, electric car lithium battery usage common sense
Many friends I have understood that electric car batteries have to follow, regardless of how many roads they run, regardless of the extent of the battery, will charge the battery after get off work, and then unplug the power supply next day. This although maintains the battery's foot electricity, but long-term use will inevitably reduce the life of the battery.
So what do we do? In fact, it is necessary to do 'not too lazy', 'Not too secure
First, it is not too lazy. Don't wait until a little power is not charged. In particular, the lithium battery is stopped after a period of time, and there is a rebound, referred to as 'recovery voltage', using recovery voltage, will cause the lithium battery to cause irreparable damage. Therefore, I can never use the back battery run. If there is no electricity on the road, it is best to turn off the power, take your own physical strength.
In addition, it is not lazy when charging. No matter if I can't charge it, I will take one night, even one to charge one day. If you are full, continue to make you feel what it feels, long, your stomach is finished. The battery is also the same, can't be filled, and time long will charge 'drum. Generally, after the charger indicator is discolored, it will continue to charge for 2 hours. At the next day, I immediately unplug the power after the next day, I immediately unplug the power; or when charging, I have to remember to put the power from the evening to pee. In fact, in life, you will better protect your items, save a lot of expenses ..
Second, it will not be too secure. There is a certain number of charging during the life of the battery, and the number of times, the power storage capacity is not. The charging frequency should be determined based on how much a daily running road and the battery condition, and the number of charging is reduced by ensuring the normal driving of the next day. It is generally necessary to master the use of six or 70% in the lithium ion battery.
