Performance in Cold Temperatures
Lead-acid batteries outperform lithium-ion batteries in extremely cold temperatures, maintaining optimal functionality while lithium-ion batteries suffer from performance degradation. This factor is particularly crucial in regions with frigid weather.
Case Study: Lithium-ion Battery Performance
A case study of an electric vehicle owner, Mr. Liu Godan, showcases the challenges of using lithium-ion batteries in cold conditions. The battery's capacity significantly diminished, requiring him to detach and carry it for recharging elsewhere. The range of the vehicle also decreased substantially, making daily travel requirements difficult to meet.
Case Study: Lead-acid Battery Performance
Contrasting Mr. Liu's experience, colleagues using lead-acid batteries observed a much smaller reduction in winter range. Even with a slight decrease, the lead-acid batteries allowed them to complete their journeys, unlike the significant range reduction experienced with lithium-ion batteries.
Weight and Cost Considerations
Lead-acid batteries are slightly heavier but more cost-effective compared to lithium-ion batteries. On the other hand, lithium-ion batteries offer a lighter profile but come with a relatively higher price tag. Additionally, lead-acid batteries provide better safety features, being less prone to issues such as overcharging and overdischarging.
Vehicle Registration and Specifications
Potential electric vehicle buyers should be mindful of adhering to vehicle specifications that meet registration standards. Overspecification in terms of weight and motor power may lead to registration denials. It is essential to consider these factors to avoid any inconvenience during the registration process.
Battery Life Considerations
Battery life is influenced by factors such as motor power, voltage, and battery capacity. The new national standard for trams in China limits the motor power to 400W or less and the voltage to ≤48V. As a result, the general new national standard for electric vehicles is 350W 48V12A.
Conclusion
When choosing between lithium-ion and lead-acid batteries for electric vehicles, it is vital to consider usage scenarios, climate conditions, and personal requirements. Lead-acid batteries excel in colder regions, providing reliable performance under low temperatures. Conversely, lithium-ion batteries are more suitable for milder climates, albeit at a higher cost. By evaluating these factors, electric vehicle owners can make an informed decision based on their specific needs.
