The problem that electric tricycle batteries cannot last a full day of delivery work is a common pain point for logistics takeout, terminal cargo distribution, and urban freight practitioners, which directly affects work efficiency, increases charging interruption time, and reduces daily income. The insufficient battery endurance for all-day delivery is not only caused by insufficient battery capacity but also related to battery aging, unreasonable configuration, improper usage habits, vehicle mechanical failure, and harsh working conditions. Comprehensive analysis of causes and targeted solutions can effectively extend battery endurance to meet full-day continuous delivery work needs.

Battery aging and capacity attenuation are the primary causes of poor endurance for delivery tricycles. Most delivery tricycles work 8 to 12 hours a day with high-frequency start-stop, continuous low-speed driving, and frequent heavy-load cargo carrying, which accelerates battery loss significantly. New batteries can maintain standard capacity and endurance, but after 6 to 12 months of high-intensity work, lead-acid batteries will have obvious plate sulfation and active material loss, with actual capacity dropping to 60% to 70% of the original. Lithium batteries will also have inconsistent cell voltage and increased internal resistance after long-term high-rate discharge, resulting in reduced effective capacity and inability to support full-day continuous work. Many practitioners ignore regular battery maintenance and continue to use aged batteries, leading to increasingly insufficient endurance.

Unreasonable battery configuration and vehicle matching are another key factor. Most entry-level delivery tricycles are equipped with 48V20Ah or 60V20Ah standard batteries, which are only suitable for daily light short-distance travel, not for high-intensity all-day delivery work with frequent load changes and complex road conditions. In urban delivery scenarios with dense communities, numerous slopes, and frequent start-stops, the battery discharge frequency and current are far higher than standard working conditions. The small-capacity battery is in a high-load discharge state for a long time, resulting in rapid power consumption and inability to last a full day. In addition, mismatched motor power and controller parameters will cause excessive current consumption, further shortening battery endurance.

Improper daily usage and charging habits will also aggravate insufficient battery endurance. Most delivery workers adopt irregular charging modes such as partial charging, delayed charging, and overcharging. Long-term partial charging leads to battery memory effect and inconsistent cell capacity; delayed charging after deep discharge causes severe plate sulfation and irreversible capacity loss; overcharging leads to battery overheating and aging acceleration. Meanwhile, frequent rapid acceleration, high-speed driving, and long-term overload cargo carrying in delivery work will greatly increase instantaneous power consumption, resulting in rapid power drop. Vehicle mechanical faults such as insufficient tire pressure, brake jamming, and bearing aging will increase driving resistance and indirectly increase battery power consumption.

To solve the problem of insufficient all-day delivery endurance, targeted improvement measures can be taken: first, replace aged batteries in time and upgrade to high-capacity 60V32Ah/45Ah lithium iron phosphate batteries suitable for high-intensity work; second, develop standardized charging habits, avoid deep discharge and partial charging, and charge fully and moderately; third, maintain the vehicle regularly, adjust brake flexibility, keep sufficient tire pressure, and reduce driving resistance; finally, optimize driving habits, avoid frequent rapid acceleration and high-speed driving, and reduce invalid power consumption. After optimization, the tricycle battery can fully meet 8 to 10 hours of full-day continuous delivery work needs.
