Introduction

Parallel batteries are a configuration where multiple batteries have their positive terminals connected together and their negative terminals connected together. This method of connection can increase the battery capacity and expand the inverter capacity. However, many people wonder if parallel batteries will discharge evenly.

Answer

In theory, parallel batteries should discharge evenly. This is because each battery is connected to the same voltage, so they should provide current at the same rate. However, in practical applications, there may be some factors that cause uneven battery discharge.

What are the influencing factors of uneven battery discharge?

• Battery Differences: Even batteries of the same model and batch may have slight differences in internal resistance, capacity, and other characteristics. These differences can cause slight inconsistencies in battery performance during discharge.
• Connection Resistance: The connection resistance between the batteries can affect the distribution of current. If the connection resistance is too large, it can cause some batteries to carry more current and discharge faster.
• Usage Conditions: If the batteries in a parallel battery pack are used for different loads, the discharge rates will also vary. For example, if one battery is used to power a high-power device and another battery is used to power a low-power device, the former will discharge faster.

How to extend the equalizing discharge time of parallel-connected batteries?

• Choose Matching Batteries: Use batteries of the same model and batch as much as possible for parallel connection.
• Reduce Connection Resistance: Use high-quality connecting cables and terminals, and ensure that the connections are secure.
• Use Batteries Equally: Avoid using the batteries in a parallel battery pack for different loads as much as possible.
• Built-in Battery Equalizer: This method can reduce the voltage difference, ensure SOC, achieve full charge and discharge, and extend battery life.

Conclusion

In general, parallel batteries should discharge evenly in theory, but there may be some factors in practical applications that cause uneven battery discharge. By choosing matching batteries, reducing connection resistance, using batteries equally, and using batteries with built-in equalizers, the equal discharge time of parallel batteries can be extended.

With the widespread adoption of electric vehicles, lithium batteries have gradually become an integral part of our daily lives. However, the potential fire hazards associated with lithium batteries have raised significant concerns. This article delves into a comparative analysis of the fire risks posed by two common lithium battery types – lithium iron phosphate (LFP) batteries and ternary batteries – exploring the underlying causes and preventive measures.

1. An Overview of Lithium Iron Phosphate (LFP) Batteries

LFP batteries utilize lithium iron phosphate (LiFePO4) as their positive electrode material, offering notable advantages such as high thermal stability, enhanced safety, and extended cycle life. These qualities have made LFP batteries a popular choice in applications like electric vehicles and energy storage systems.

2. Delving into Ternary Batteries

Ternary batteries, also known as NCM batteries, feature a positive electrode composed of a composite of three metal elements: nickel (Ni), cobalt (Co), and manganese (Mn). They are characterized by high energy density, long cycle life, and excellent low-temperature performance, making them a prevalent choice for powering electric vehicles.

3. A Comparative Analysis of LFP and Ternary Battery Flash Points

As evident from the flash point data, LFP batteries exhibit a significantly higher flash point compared to ternary batteries. This implies that LFP batteries are less prone to combustion in the event of accidents or malfunctions.

4. Unveiling the Factors Behind Flash Point Discrepancies

The disparity in flash points between LFP and ternary batteries stems primarily from the distinct chemical properties of their positive electrode materials. LFP boasts exceptional thermal stability, even at elevated temperatures, due to its stable crystal structure. Consequently, it possesses a higher flash point. In contrast, the ternary materials (Ni, Co, Mn) exhibit relative instability, rendering them more susceptible to decomposition under high temperatures. This decomposition releases oxygen, leading to an increase in internal battery pressure and potentially triggering combustion.

5. Factors Influencing Lithium Battery Fire Hazards

Apart from the flash point of the positive electrode material, several other factors contribute to the fire risk of lithium batteries, including:

• Battery Structure Design: A well-designed battery structure effectively minimizes the risk of internal short circuits.
• Battery Manufacturing Processes: Advanced manufacturing techniques enhance battery consistency and safety.
• Battery Management Systems (BMS): Robust BMS continuously monitor battery status, preventing abnormal conditions like overcharging and overdischarging.

6. Preventive Measures to Combat Lithium Battery Fire Hazards

To effectively mitigate lithium battery fire hazards, adhering to the following guidelines is crucial:

• Opt for high-quality batteries from reputable manufacturers, carefully inspecting the production date and shelf life.
• Practice proper battery usage and maintenance, avoiding overcharging, overdischarging, short circuits, and exposure to extreme temperatures.
• Conduct regular battery inspections, promptly replacing any cells exhibiting abnormalities.
• Responsibly recycle used batteries, refraining from improper disposal.

7. Conclusion

In summary, LFP batteries, owing to their higher flash point and superior thermal stability, demonstrate a clear safety advantage over ternary batteries. When selecting lithium batteries, it is essential to carefully consider both performance and safety factors, while implementing appropriate preventive measures to ensure safe battery operation.

As lithium battery applications continue to expand, their packaging methods have become a focal point of attention.
