The 12 v lithium battery charge and discharge voltage parameter

by:dcfpower     2020-11-15

12 v lithium polymer battery have typically lithium ion battery charge and discharge performance of similar, but, above the technical parameters of the actual will be slightly difference, on the basis of the present stage 12 v lithium-ion polymer battery general technical level, the technical parameters shall be set up charge and discharge and the self-discharge process. 12 v lithium polymer battery and lithium battery normally have similar charge and discharge performance, but a slightly different technical parameters on the actual technical parameters. According to the present stage 12 v common technical strength, polymer lithium battery should be rechargeable lithium battery life and set its technical parameters. Ok today we have 12 v lithium battery charge and discharge voltage technical parameters.

12 v lithium battery pack charging and discharging voltage

& other; Voltage 14 - - The appearance of the 16 v, after discharge, the voltage stability in the 12 v ~ 12. 3 v, when the voltage drop to 10. 8 v, discharge end. The charge. If not be 12 v, highest can charge to 2 per unit. 7 v; Discharging termination voltage 1. 8V。 The charge.

a.

1, 12 V lithium battery head should comply with the third ring road performance of li-ion batteries. So the original 12 v li-ion battery charger is good, when the original charge head is damaged, can not blindly follow any other charge on the head of choose and buy the 12 v lithium battery, more good for manufacturers to buy original battery reaction. 12 v lithium battery charger should comply with the lithium battery used in the three phase characteristics of need and complete charge, constant current and constant voltage charging, charging three stages. Therefore, the original 12 v li-ion battery charger is good, when the original charger is damaged, can not blindly follow the choose and buy other charger for 12 v li-ion battery, the choose and buy good looking for battery manufacturer.

2。 Working temperature: when charging 12 v lithium battery pack, try not to work temperature over 040 ℃. For 12 v li-ion battery charging, environment temperature can not exceed 0 ~ 40 ℃ the range.

3。 cut-off voltage: 12 v lithium polymer battery cut-off voltage, need to choose balance charging ways, in order to ensure the working voltage of a single lithium battery is not easy. Charge cut-off voltage: 12 v lithium-ion polymer battery cut-off voltage in 12. 6 v, adopts balance charging method, is required to ensure that only the batteries voltage does not exceed 4. 2V。

4。 Current: if the battery can charge in the case of an emergency, will not charge more than one degree Celsius. If it is in an urgent need 0 cases available. 2 c, usually no more than 1 c.

2. Discharge

1. Working temperature: is the 12 v charging and discharging lithium ion work attitude, temperature was minus 20 to 60 c. Discharge is the working state of the 12 v lithium-ion batteries, temperature requirements for - at this time 20~60℃。

2。 Used to terminate the working voltage of the rechargeable lithium polymer 12 v electric charge and discharge end is working voltage specification, some can be set to 9 v. 12 v lithium polymer battery discharging termination voltage standard is 8. 25 v, some can be set to 9 v.

the charge and discharge current: 12 v lithium polymer battery also has large current, large capacity and other properties. 12 v lithium-ion polymer battery also has a large current, large capacity, such as type, can carry out high power discharge of polymer lithium battery pack electric current within the scope of product specification should be adjusted.

3. Self-discharge

shall store the 12 v lithium ion battery in the 40 - Activation of 60 ℃ is a very natural, are unlikely to at any time maintenance, such as apple mobile charging. 12 v lithium battery pack storage also will be confused by the service life of lithium batteries, lithium battery service life for a long time can cause power loss, therefore we must for 12 v lithium-ion batteries used in advance to make sufficient preparations.

1。 Charge on time: 12 v lithium-ion battery charging on time, to keep the working voltage in the middle, this is because the lithium ion battery charging at any time all have no memory. For 12 v li-ion battery recharged regularly, keep voltage in 10. 8 v - 11. Between 7 v, it is because lithium batteries have no memory effect can charge at any time.

2。 Make sure the working voltage of charge and discharge does not rise, such as in a no electricity in the whole process of using, should stop charging. Ensure the discharging termination voltage is not breached, if a power shortfall in use process, should be determined to stop using, for lithium batteries.
