CR2430 battery

What are the charging characteristics of CR2430 battery?

During the battery manufacturing process, due to production processes and other reasons, batteries manufactured in the same batch have differences in volume, internal resistance, etc.;

Rechargeable lithium-ion batteries have different lifespans. After long-term accumulation, the battery power will be different;

During the use of batteries, differences in application environments such as temperature and circuit boards lead to imbalances in battery power.

Lithium Ion Battery Rechargeable Battery Balance Battery Charging Method.

In order to reduce the harm of imbalance to CR2430 battery, a balanced power supply circuit should be used when charging the battery.

There are currently two ways to balance the management of lithium-ion batteries, one is the energy consumption type, and the other is the feedback type. The calorie consumption type is to provide a series loop for a single battery, so that a single battery with a high voltage can separate electromagnetic energy to achieve balance. The feedback type refers to the deviation energy between units being sent into the lithium-ion battery pack or some units in the lithium-ion battery pack through the energy converter.

Theoretically, feedback does not consume energy and can achieve a stable balance while ignoring transformation efficiency. However, due to the complicated control measures and high manufacturing cost of the feedback design method, this charging head adopts an energy-consuming design method.

Since AC resistance, polarization voltage, and maximum usable volume are actual important parameters of the battery, during one or several consecutive battery charging processes, the SOC of the battery basically does not change, so the lithium-ion battery pack The balance is important and is accomplished by regulating the SOC of each individual rechargeable battery. Through scientific research, it is determined that SOC is used as the balance reference target and the balance target is relatively fixed, the balance time is fully utilized, the balance utilization rate is increased, and the balance volume is reduced.

Taking the SOC of the rechargeable battery as the control indicator and charging the independent rechargeable battery, the difference between the SOC and the rechargeable battery is reduced. The first is to clarify the balance target and set it as the average state of concentration (SOC) of the lithium-ion battery pack to improve balance efficiency and take full advantage of battery charge balance; at the same time, balance control is also set With (dSOC), the charge and discharge balance is carried out for the unit with higher SOC, and the battery charge balance is carried out for the opposite unit.

The key balancing charging technologies of general CR2430 battery include stable separation resistance, short-circuit separation resistance, average voltage balancing charging, switch capacitor balancing charging, blood pressure reducing SPWM balancing charging, inductor balancing charging, etc. When charging integrated lithium-ion batteries in series, each battery should be charged evenly, otherwise the performance and service life of the entire set of batteries will be affected during use.
