Cropper 12V33AH lithium battery pack design example

Cropper 12V33AH lithium battery pack design exampleThe base station battery is from the current use, there is a problem that the battery capacity is too fast, the service life is short, and the battery capacity is only 30% ~ 40% of the battery, and some is only 10% ~ 20%, and most base stations battery operations have been operated in 1 to 4 years, with only about 50% of their nominal capacity, far from its design life, compared with the exchange of exchanges, and its service life is also Greatly reduced. This paper analyzes the damage causes of the battery during the operation of the base station, and proposes a method of extending the service life of the base station battery.

The Huizhong lithium battery has a high-spirited characteristics of the discharge platform, high safety, long life, and excellent low temperature performance.
First, the definition of battery life

The service life of the battery is generally referring to the use period of the floating state. For batteries operating in non-floating state, their life is measured from two dimensions of circulation discharge and discharge depth, as shown in Table 1. So don't simply use how many years can use to measure the life of the battery.

For the number of cyclic discharges of the battery, it must be sufficiently electrical energy after the battery is discharged, and the power charging time is required for at least 24 hours (according to YD / T799-2002). For the insufficient charging, the number of cyclic discharge is difficult to determine, and it is definitely lower than the data described in Table 1.

The impact of discharge depth on battery life is also very large, the deeper the battery discharge depth, the less the number of cycles, as shown in Table 1, so the depth discharge should be avoided.
