• Select cells with lower energy density.

Choosing cells with a lower energy density may also lead to reduced overall costs in lithium battery packs. Although this may diminish the total capacity, the individual cells typically come at a lower cost.

For example, let’s consider a 3S2P lithium-ion setup with cells rated at mAh and 3.7V. This configuration results in a total capacity of 55.5Wh.

Now, by substituting those modules with mAh cells maintaining the same voltage, total capacity drops to 37Wh. By leveraging 21 cells (3 in series and 7 parallel) instead of mAh rated ones, the approach preserves almost 55.5Wh capacity, effectively reducing costs while keeping effectiveness stable.

Employing lower energy density offers a potential avenue for reducing expenses when high-capacity alternatives become financially burdensome.

Conversely, utilizing lower C-rate cells presents another opportunity for cost reduction. These cells generally cost less than their counterparts, although it’s vital to ensure they still meet the required performance metrics.

For a 12V 20Ah battery, switching to mAh capacity cells at a C-rate of 1C requires 48 cells, whereas opting for mAh capacity cells with a 0.5C rate might only necessitate 40 cells, lowering cost per unit while keeping the pack operational.

While reducing the number of cells or opting for smaller capacity ones can effectively lower costs for lithium battery packs, be mindful of increased size and weight as one notable downside.

Important Note: This approach is particularly advantageous for bulk production and shipping scenarios. Using lighter batteries reduces shipping expenses, showcasing practicality in large-scale deployments.

Implementing smaller capacity cells represents a viable solution for reducing lithium battery pack expenditures.

• Opt for an affordable battery management system

To minimize battery management system expenses, consider scaling back certain functionalities, such as cell balancing or temperature monitoring. While crucial for battery health, these features can inflate BMS costs.

An example would be a BMS with a cell balancing feature that ensures uniform charging and discharging. Although helpful in extending battery life, the complexity and cost of this feature may outweigh the benefits for smaller packs.

Temperature sensors track battery temperatures, but their inclusion can escalate costs significantly—some sensors range up to 10 USD. Omitting them could streamline BMS costs while maintaining adequate safety for designs with minimal current consumption.

Any modifications to the BMS should align with industry standards and prioritize safety to prevent compromising pack reliability.

Another method for lowering product costs includes sourcing a less expensive battery management system. This could entail procuring from alternative suppliers or adopting designs that require fewer parts while ensuring safety standards remain intact.

The product's enclosure/packaging also plays a role in cost management. Selecting more budget-friendly options can reduce expenses, but be cautious about potential impacts on safety and customer perception.

Exploring cheaper materials, such as biodegradable options, may offer cost savings while appealing to environmentally-conscious consumers.

In addition to customizing components, achieving cohesion among these components in the overall battery pack system is vital. Factors like wiring, connectors, and system layout all contribute to performance and costs.

When brainstorming, always consider the potential long-term impact on battery pack quality and reliability. Balancing potential savings against replacements and repairs is crucial to ascertain overall cost benefits.

In summary, implementing a variety of strategies can assist in lowering lithium battery pack expenses.
