Lithium ion battery charging time calculation, charging method of lithium ion battery. Lithium-ion battery charging time, from difficult to the extent, the operation problem is not large, understand the origin of the charging time of lithium ion battery more helpful in theory and practice. Keep the lithium ion battery moderately charge, discharge can extend battery life.
This paper understands the charging time of lithium ion battery charging time, charging method of lithium ion battery. Lithium-ion battery charging time calculation method Theoretically lithium ion battery charging time is the ratio of battery nominal capacity and current: lithium ion battery charging time (h) = battery capacity (MAH) ¡Â Charging current (MA) because charging Impedance occurs, in order to offset the impedance, practice charging time is greater than the above theoretical charging time, in order to make the lithium ion battery charging time meet the full power requirements of practice, it is generally necessary to set a larger size according to the battery capacity ratio of the charging current. 1 coefficient.
Lithium-ion battery charging time (hour) = coefficient of rechargeable battery capacity (MAH) / charging current (mA) * 1.5. If you use 1600mAh charge lithium ion battery, the charger is charged with 400mA current, then the charging time is: 600/400 * 1.
5 = 6 hours (note: this method does not apply new purchase or long-term unused rechargeable battery) Portable Electronics The lithium ion battery charging time of the product is also specified in accordance with the above formula, which is generally equipped with the corresponding constant current charger, which is full of control of the lithium ion battery charger. The indicator indicates that the battery will be alarm signal when the battery is fully charged. Therefore, consumers only need to operate in accordance with the instructions, do not have to charge the lithium-ion battery for a long time and worry.
In practice, the charging time of the lithium ion battery is longer than the theoretical time, because there is energy cost in charging. Enhancement of charging voltage can progress to charging power. Electric car lithium-ion batteries is generally overall for a long time? Generally, the new electric car lithium-ion battery is new, the capacity is also large, the charging time is longer, will reach 10 hours or more, will be faster and faster later, about 2 months will be reduced to 6 hours, After that, it will last for half a year, and the lithium-ion battery capacity will continue to attenuate.
It can be filled with 3-4 hours after 1 year. Of course, the lithium-ion battery is almost changed or maintained. Electric vehicle lithium-ion battery charger is three-stage charging, divided into constant pressure stages, constant current stage, trickle stage.
The first two stages are the important stage of charging. After completion, the battery is basically full, the lamp will become green, enter the trickle phase, and protect the battery at this time not to unplug the power, continue to charge for 1-2 hours, can effectively add lithium-ion battery life, but Don't exceed 8 hours after changing green. Generally charging, it is best to write in accordance with the specifications, if not, the capacity of the lithium-ion battery and the current of the charger are mostly calculated, such as the lithium-ion battery of 48V / 20A, the charger is 5A, It is necessary to charge more than a little more, if you are 10A chargers, more than two hours, 20A chargers are charged an hour.
Lithium-ion battery charging method 1. When the lithium ion battery is charged, the charger is preferably selected to select the original charger of the original, otherwise it will affect or damage the polymer lithium-ion battery. 2.
Activation of lithium-ion batteries does not have a special method, and the lithium ion battery will naturally activate in the machine. If you insist on the "first three-hour 12-hour long charging activation" method, there will be no effect. 3.
Lithium-ion battery charging temperature range: 0 ~ 45 degrees Celsius, lithium ion battery discharge temperature range 0 ~ 60 degrees Celsius. 4. Lithium-ion battery must prevent excessive charge of the battery, and a lithium-ion battery will cause serious damage to battery performance, and even explode.
5. The charging and discharge characteristics of the lithium-ion battery and nickel battery have a very large difference. It is necessary for more than 12 hours without charging time.
It is repeated three times. Charge. The above is a charging method of lithium ion battery charging time, charging method of lithium ion battery.
I hope to give you a certain help, thank you for watching.
