How to prevent the lithium polymer battery charge?

Source: 2020 - 04 - 11 hits have: first lithium polymer battery is charging when the polymer lithium-ion batteries used in mobile phones and laptop computers, they will usually be machine monitoring, to prevent excessive charging. Its function is to once found any abnormal, immediately stop charging. Therefore, using this kind of machine for rechargeable lithium polymer battery does not need to charge. Lithium polymer battery, such as those used in the model of car batteries, are required to run away from their environment more portable. As a result, which has the function of the substrate is not installed on the battery, but is installed on the charger. Model car use lithium polymer batteries with different capacity ( Unit time available, current: mAh) , charge and discharge of tolerance ( Units: CmA, C) Such as different products according to the composition of the battery, so you can change the corresponding charger Settings, or use a variety of battery chargers for. Otherwise, the charger has no effect on the additional function, sometimes there will be a charge. In addition, pay attention to when charging around burning material, don't put it in the combustible special bag, and frequent checks in the whole process, to prevent the battery heating 'inflation' and other anomalies. ( 1) Charging sets the lithium-ion polymer battery to nickel chrome cell ( Nickel metal hydride rechargeable battery) 。 When the nickel cadmium battery voltage will change its characteristics. Detect this change and stop charging battery. Lithium polymer battery without this ability, so they are easy to overcharge. ( 2) Formation of lithium polymer battery when the battery voltage imbalance, charging set is not right. Lithium polymer battery is the combination of a number of battery is arranged together, due to the use fixed number of year or different using conditions, the battery voltage balance is sometimes different. In order to improve the situation for the battery status, respectively, and each battery charger, we will charge, the charging method is called balance when the battery voltage produced when different lithium polymer battery, if you don't do balance charging, the arrangement of the battery will be observed as a whole, even if the voltage is normal, separate the battery will happen. ( 3) Set the error when charging. When the number of lithium polymer battery charging and charging ways' voltage current is not correct, there will be charge too much.
