Moreover, lithium batteries boast a long service life, reducing the hassle and costs associated with frequent battery replacements and significantly boosting delivery efficiency.

I. High‑intensity delivery, the battery dilemma

1、 Range anxiety

In the daily routine of package delivery, couriers are constantly on the move. Take an average courier as an example: each day, they navigate the city’s streets and alleys, delivering to areas that may span multiple residential neighborhoods, commercial districts, and office buildings. From the moment they set out in the morning until they finish work in the evening, their total mileage often exceeds 100 Kilometers. In this process, the traditional… Lead-acid Battery life becomes a significant constraint. Many delivery drivers report that during peak periods, they often face the awkward situation of their batteries running out mid‑route. For example, during an afternoon delivery shift, with several hours still left before the day’s deliveries are due to wrap up, the battery may already be nearly depleted, forcing them to return to the depot early to recharge. This not only prevents them from completing their scheduled deliveries on time but can also negatively impact customers’ receiving experience. Furthermore, to avoid running out of power, some drivers are compelled to reduce the number of packages per trip and make more frequent round trips to the depot, which inevitably undermines delivery efficiency.

2、 Charging time

The delivery workers’ pace is extremely fast, with their daily working hours typically around… 10 More than an hour, or even longer. Under such intense workloads, charging time becomes a thorny issue. Typically, conventional… Lead-acid The battery charging time requires 6 - 8 Hours, or even longer. This means that if a courier charges their vehicle during work breaks, they may have to wait several hours before they can resume deliveries—something that is simply unacceptable in the fast‑paced world of express delivery. For example, during their lunch break, a courier has only… 1 - 2 Hours simply cannot meet the demand. Lead-acid Battery charging requirements. Even charging after work in the evening can disrupt the next day’s schedule.

3、 Environmental adaptability

Lead-acid Battery performance is also significantly affected by ambient temperature. In low-temperature environments, Lead-acid Battery The electrolyte viscosity increases, the diffusion rate decreases, and the electrode reaction kinetics slow down, Causes the battery Capacity degradation and reduced charging efficiency . In the cold winter, when the temperature drops below 0℃ At that time, many delivery drivers noticed a significant acceleration in battery degradation; previously, a full charge would allow them to travel… 100  A battery with a range of kilometers may only be able to travel in low temperatures. 50  Kilometers, or even fewer. This not only increases the number of times couriers need to recharge their vehicles but may also prevent them from completing delivery assignments.

II. The Solution Revealed

1 , Alternatives to Lead-Acid Batteries

In responding to Electric When there is a high‑intensity delivery demand for tricycle batteries, Battery type The choice is crucial. Currently, the common electric… on the market There are two main types of batteries: one is the traditional lead-acid battery. Although it is bulky, has a short service life, and performs poorly at low temperatures, it offers a significant cost advantage and is widely available. 0.35 Yuan /Wh , a group 48V20Ah Lead-acid batteries can be traded in at a favorable trade-in price. 350 Around yuan; the other category is lithium batteries. As mentioned above, thanks to their outstanding performance, lithium batteries have emerged as a powerful alternative to lead-acid batteries, effectively meeting the demands of high-intensity delivery operations.

Among them, lithium batteries are predominantly ternary lithium and lithium iron phosphate. Ternary lithium battery Although Its overall performance is quite outstanding, However, security still needs to be improved. In contrast, Lithium iron phosphate batteries are renowned for their high safety and long cycle life, demonstrating stable performance in high-temperature environments and being less prone to thermal runaway and other safety issues, making them highly suitable for… Electric Tricycles are used in a variety of complex environments. For example, the Ginkgo Battery has launched 60V100Ah、72V100Ah Large-capacity lithium iron phosphate batteries can meet the needs of electric tricycles in the express delivery sector. 80 to 120 The demand for a range of over kilometers. And in -20 °C Under these conditions, the range can still be maintained at 80% That’s all. The service life can reach 8-10 Over the course of a year, when calculated in total, the full‑cycle cost of ownership will not exceed that of lead‑acid batteries.

2 , Charging Efficiency and Fast-Charging Technology

Compared with lead-acid batteries 6-8 With charging cycles lasting several hours, lithium batteries have also seen significant improvements in charging efficiency. Power‑type lithium batteries generally support continuous… 0.5C , peak 2C The charging rate mentioned above—what does that mean? For example, if sustained… 0.5C Charging, 2 It can be fully charged in just a few hours; if… 2C In peak fast‑charging mode, it can be fully charged in just half an hour. 80% That is all. It significantly reduces charging time, enabling delivery personnel to make more efficient use of their breaks for charging.

At present, fast-charging technology is being vigorously promoted and widely adopted. The principle behind fast-charging technology is primarily to shorten charging time by increasing the charging power. According to the power formula, P = UI (Power =  Voltage × Current), fast charging can be achieved by increasing the voltage, boosting the current, or simultaneously raising both the voltage and the current.

There are several common fast-charging solutions. High-power fast chargers are a widely used approach; by increasing the charger’s output power, they can deliver substantial energy to lithium batteries in a short period. For example, some high-power fast chargers can achieve an output power of  30 00W (Wa) Even higher, compared to Traditional lead-acid of Several hundred watts Charger—charging speed has been significantly improved.

An intelligent charging management system is also an important fast‑charging technology. This system continuously monitors the battery’s state of charge and, based on parameters such as voltage, current, and temperature, intelligently adjusts the charging strategy. During the initial phase of charging, when the battery level is low, it employs a higher current to accelerate charging and reduce overall charging time; as the battery approaches full charge, it automatically reduces the charging current to prevent overcharging, thereby protecting the battery and extending its lifespan. Furthermore, the system can adapt charging parameters according to different battery types and usage scenarios, optimizing charging performance. For example, in hot summer conditions, if the battery temperature rises excessively, the system will automatically lower the charging current to avoid overheating; in cold winter weather, it will slightly increase the charging voltage to ensure proper charging.

3、 Battery-swapping model is on the rise.

Battery-swapping, as a new method of energy replenishment, is steadily gaining traction and attracting attention from the express delivery industry. The battery‑swapping process is relatively straightforward: when a courier’s battery is running low, they simply need to… Electric tricycle Remove the depleted battery, then head to a nearby battery-swap station to exchange it for a fully charged one, and you can resume your delivery duties. The entire swap process typically takes only a few minutes, significantly cutting down on time compared with conventional charging methods.

Compared with charging, battery-swap offers distinct advantages. It enables rapid energy replenishment, eliminating long wait times for charging and thereby enhancing… Electric tricycle Improving operational efficiency, delivery personnel can quickly restore their vehicles’ range during the day—even when battery levels are low—by swapping out depleted batteries, thereby ensuring timely completion of delivery tasks. The battery‑swapping model also helps reduce costs for both courier companies and individual couriers. For carriers, it eliminates the need for substantial investment in charging infrastructure; they simply partner with battery‑swapping operators to provide this service to their drivers. For couriers, there is no requirement to purchase expensive lithium batteries—only the costs of battery leasing and swapping are incurred, significantly lowering upfront capital outlays. Moreover, the battery‑swapping approach facilitates centralized management and maintenance: operators can perform standardized inspections, routine upkeep, and upgrades, enhancing battery safety and extending their service life.
