[PDF Version]Thermal Characteristics of Lithium-Ion Batteries Lithium-ion batteries, known for their nonhomogeneous composition, exhibit diverse heating patterns on the surface of battery cells.
As rechargeable batteries, lithium-ion batteries serve as power sources in various application systems. Temperature, as a critical factor, significantly impacts on the performance of lithium-ion batteries and also limits the application of lithium-ion batteries. Moreover, different temperature conditions result in different adverse effects.
Research indicates that the optimal operating temperature range for lithium-ion batteries is between 20 and 50 degrees Celsius [7, 8]. Both excessively high and low temperatures can adversely affect battery performance and safety.
Therefore, directly computing the thermal conductivity of lithium-ion battery components and cumulatively determining the battery's thermal conductivity is unreliable when the uncertainty of contact thermal resistance is not considered.
The results indicated that the specific heat of the batteries ranged from 870 to 1040 J kg -1 °C -1 at 25 °C. The specific heat of the batteries increased with temperature and exhibited less sensitivity to the state of charge (SOC), varying depending on the type of battery materials.
The interaction between temperature regulation and lithium-ion batteries is pivotal due to the intrinsic heat generation within these energy storage systems.

Hardware-type protection board: Use special lithium battery protection chip, when the battery voltage reaches the upper limit or lower limit, the control switch device MOS tube cut off the charging circuit or discharging circuit, to achieve the purpose of protecting the battery pack. Characteristics: 1.
It is an electronic device that can monitor and manage the battery. It can control the charging and discharging process of the battery by collecting and calculating the voltage, current, temperature and SOC of the storage, so as to realize the protection of the battery and improve the comprehensive performance of the battery.
The over-current capacity of the protective board is determined by the over-current capacity and quantity of the MOS tube. The MOS tube accounts for most of the cost of the protective board. Generally speaking, the charging current is smaller and the discharge current is larger.
The MOS tube of the protection board is relatively expensive, in the final analysis, the purpose of the separate protection board is to make reasonable use of the MOS tube flow capacity, not waste and save money. The basic principle:
The number of charging MOS tubes of the common port protection board is equal to the number of discharging MOS tubes, and the total number of MOS tubes must be even number. The number of charging MOS tubes of separate port protection boards is generally less than discharging MOS tubes.

Depth of discharge (DoD) is an important parameter appearing in the context of rechargeable battery operation. Two non-identical definitions can be found in commercial and scientific sources. The depth of discharge is defined as: the maximum fraction of a battery's capacity (given in Ah) which is. During their use, secondary batteries are repeatedly charged and discharged within a certain range of state of charge. For many, it is beneficial or even mandatory for safety. Using definition (2), the depth of discharge of a charged 90 Ah battery is discharged for 20 minutes at a constant current of 50 A is calculated by: • • • • •.
The discharging of a battery is generally limited to 80% of the nominal capacity. For solar applications, the discharge depth hardly exceeds 60%. Accumulators are often oversized in order to increase their lifespan [22, 26]. Rui Xiong, ... Fengchun Sun, in Renewable and Sustainable Energy Reviews, 2020
The maximum daily depth of discharge may either be set arbitrarily (e.g., a figure of 20–30% is common), or it may be worked out from the known daily cycle, the cycle life of the battery in question and the required lifetime (if cycling is the limiting factor). For seasonal storage (if used) a maximum depth of discharge needs to be set.
Battery Discharge Characteristics The battery voltage near the end of useful discharge is determined by the lowest capacity cell in the battery. The knee of the discharge characteristic is sharper than that of the individual cells and once the lowest cell is totally expended, the battery voltage drops rapidly.
The depth of discharge (DOD) is influential in the cycle performance of lithium-ion batteries, but the influences vary greatly with different cathode materials as shown in Table 3 [67–69]. Compared with LFP and NCM batteries, the cycle performance of NCA batteries is closely related to the range of DOD.
Depth of discharge is of considerable importance for Pb batteries since they rarely survive a full discharge. However, this parameter does not have much importance for Ni-Cd which can completely discharge. The discharging of a battery is generally limited to 80% of the nominal capacity.
Depth of Discharge (DOD) A battery's lifetime is highly dependent on the DOD. The DOD indicates the percentage of the battery that has been discharged relative to the battery's overall capacity. Deep discharge reduces the battery's cycle life, as shown in Fig. 1. Also, overcharging can cause unstable conditions.
