What Should Be Considered to Design The EV Battery?

As EVs become more popular, the demand for lithium-ion batteries to power them is also rising. But what factors should be considered when designing these batteries? In this post, we’ll look at some of the key considerations for those planning to create an Electric Car lithium battery from the manufacturer’s perspective. So, if you’re curious about what goes into making these batteries, read on!

What Should Be Considered to Design The EV Lithium Battery?

Designing an EV Lithium Battery – Key Considerations
There are many considerations that need to be taken into account when designing an EV lithium battery: battery cell technology, pack technology, and BMS technology. These 3 points are from the Power Battery System. At the same time, the whole life cycle of EV Lithium Battery is also important. Let’s take a closer look at each of these factors.

Overview

1. Battery Cell Technology


2. EV Lithium Battery Pack Technology


3. BMS Technology


4. The Whole Life Cycle of EV Lithium Battery


5. Conclusion

Bonnen’s engineering team created two “iron triangle” drawings to illustrate which aspects of a battery pack system are important.

Battery Cell Technology

Lithium-ion batteries are the most popular type of battery used in power battery systems. Lithium-ion batteries are known for their high energy density, which means that they can store a large amount of energy in a small space. Additionally, lithium-ion batteries have a long lifespan and do not require regular maintenance.

1. Increased Efficiency
One of the primary benefits of Electric Car lithium battery cell technology is that it is much more efficient than traditional lead-acid batteries. Lead-acid batteries typically have an efficiency of around 50%, while EV lithium batteries can have an efficiency of up to 99%. This means that more of the energy stored in the battery is converted into usable electricity, which can help to increase the range of electric vehicles.

2. Increased Power Density
EV lithium battery cells also have a much higher power density than lead-acid batteries. Power density is a measure of how much power can be stored in a given amount of space. EV lithium batteries can store up to three times as much power in the same amount of space as a lead-acid battery, which means that electric vehicles can have smaller and lighter batteries without sacrificing range.

3. Faster Charging
Another benefit of EV lithium battery cell technology is that it allows for much faster charging than lead-acid batteries. Lead-acid batteries typically take several hours to charge, while EV lithium batteries can be charged in as little as 15 minutes. This can be a major advantage for people who need to charge their electric vehicles quickly, such as those who live in urban areas where there are few public charging stations.

4. Lower Cost
EV lithium battery cell technology is also becoming more affordable as production costs continue to decrease. The cost of EV lithium batteries has fallen by more than 80% since 2010, making them much more accessible to consumers. As battery prices continue to fall, it is expected that the adoption of electric vehicles will continue to increase.

5. Reduced Environmental Impact
Finally, EV lithium battery cell technology also has a lower environmental impact than traditional lead-acid batteries. Lead-acid batteries contain toxic chemicals that can leak into the environment and cause pollution, while EV lithium batteries are made from safe materials that are not harmful to the environment.

EV Lithium Battery Pack Technology

An Electric Car lithium battery pack is a type of battery that is used in electric vehicles. Lithium-ion battery packs are the most common type of battery used in EVs, as they have a high energy density and are relatively lightweight.

1. Design Considerations
When designing a lithium battery pack for an electric vehicle (EV), there are a few key considerations that must be taken into account. The first is the voltage of the battery pack, which must be matched to the voltage of the EV’s motor. The second is the capacity of the battery pack, which determines how far the EV can travel on a single charge. The third is the discharge rate of the battery pack, which determines how much power the EV can deliver.

2. Voltage
The voltage of a battery pack is measured in volts (V). The voltage of an EV’s motor must be matched to the voltage of the battery pack in order for the motor to function properly. Most EV motors have a voltage of 400-800 V, although some may have a higher or lower voltage.

3. Capacity
The capacity of a battery pack is measured in amp hours (Ah). The capacity of a battery pack determines how much energy it can store and how long it will last before needing to be recharged.

4. Discharge Rate
The discharge rate of a battery pack is measured in amps (A). The discharge rate determines how much power the battery pack can deliver and how quickly it will run out of energy.

5. Other Considerations
There are a few other considerations that should be taken into account when designing a lithium battery pack for an EV. One is the operating temperature range of the battery pack, as batteries can become damaged if they are exposed to extreme temperatures. Another is the self-discharge rate of the battery pack, as batteries will slowly lose their charge even when not in use.

BMS Technology

BMS is a type of battery management system that is used in electric vehicle lithium battery packs.
Good and suitable BMS helps to improve the performance of electric vehicles by managing the battery pack and ensuring that it is operating at peak efficiency. And it also helps to prolong the life of the battery pack by preventing it from being overcharged or discharged too deeply. BMS technology is an important part of electric vehicle design and can help to improve the range, performance, and efficiency of the vehicle. At the same time, BMS technology is available from a number of different suppliers and can be customized to meet the specific needs of an electric vehicle.

The Whole Life Cycle of EV Lithium Battery

As the Electric Car lithium battery buyer, it is important to be aware of the whole life cycle of the battery system product in order to ensure safety and longevity. The second diagram shows that the battery system product should define and control the whole life cycle according to the concept of automotive development, from product development and manufacturing to product maintenance. This will ensure good use of the lithium battery. Only safety and longevity genes battery technology can realize the whole system’s safety and reliability. We must be diligent in our lithium battery research to ensure that we are using the best possible technology for our products.
