Something about the relationship between the lithium battery and lithium battery pack

Connection between the lithium battery and lithium battery. As for the title, those who do not know much about lithium battery readers might think this article is the same as the lithium-ion batteries. But the battery included in the lithium-ion battery pack. Therefore, the following is trying to express is the content of the lithium-ion battery pack. Lithium battery pack by battery core, protection plate and shell of three parts. The battery consists of lithium battery, protection board for series of lithium battery charge and discharge protection. After good electricity, to ensure that every single cells is less than the voltage difference between set value ( As a general rule, be & plusmn; 20mV) , the realization of each monomer battery charge in the battery pack. Check each monomer batteries in the battery pack of overvoltage, undervoltage, over current, short circuit, over temperature, protect and extend battery life; In the process of discharging operation, low voltage protection can avoid single battery due to over discharge damage. There are two kinds of lithium-ion battery shell material, such as aluminum and steel shell soft package and hard, but soft package now lithium-ion batteries is more popular with manufacturers in the market. Lithium-ion batteries have a circuit in parallel and series circuit. Due to a single lithium-ion battery in a brief series circuit, when charging lithium battery series, in the capacity, internal resistance, attenuation characteristic differences exist, self-discharge, and other functions. Battery capacity in the smallest single piece of lithium ion battery will be charging as soon as possible. At this point, other lithium ion battery not completely charging, charging so if they are in series, a single lithium-ion battery has been completely charge may be recharging. And the function of the lithium battery overcharge would result in grave damage to the battery, and even may lead to formation of casualties. As a result, the lithium battery of lithium battery of battery cells combined with parallel, serial, in order to ensure the safety of the lithium battery pack, for the battery. In addition to parallel and series circuit connection, between processing system and battery charger is compatible with each other. Batteries processing system is the most comprehensive equipment function and the status of the battery, so the connection between the processing system and battery charger can make a battery charger to understand the information in real time, and then more effectively solve the problem of lithium batteries. Lithium-ion battery pack processing system and the battery charger harmonic coordination method under the principle of charging battery processing system will be the total voltage, the highest monomer battery voltage, temperature, temperature rise, the largest promised to recharge battery voltage and maximum voltage, maximum promised monomer promised to parameters such as charging current real-time transmission to the charger, the charger can according to the battery information processing system to supply their charging strategy and output current changes. When the battery processing system to supply the biggest promise when the charging current is greater than the solution current capacity of the charger, the charger will be charging according to the solution of the maximum output current. Battery when battery voltage and temperature beyond the constraint processing system can detect and tell the charger output current changes in a timely manner. When the charging current is greater than the maximum charging current promised, chargers began to follow the biggest promise charging current, effectively prevent the battery overcharge, reach extends battery life intention. Once appear problem, in the process of charging battery processing system biggest promise charging current can be set to 0, forcing the charger suspension, avoid accidents, ensure the security of the charge.
