The market demand for electric freight vehicles is growing. Light and heavy freight vehicles play an important role in different application scenarios, and power battery, as its core drive system, directly affects the performance, efficiency and economy of vehicles. This article will discuss the main differences between the power batteries of light and heavy freight vehicles, including battery type, capacity, power, cost and application scenarios.

I. Battery type

1. Light freight vehicle

light freight vehicles usually refer to commercial vehicles with a total weight of less than 3.5 tons, such as small delivery vehicles and light trucks. Due to its relatively small size and flexible usage scenarios, light freight vehicles usually use lithium-ion batteries. This kind of battery has high energy density and charging efficiency, and can meet the demand of frequent start and stop of city distribution.

2. Heavy freight cars

heavy freight vehicles refer to vehicles with a total weight of more than 3.5 tons, such as heavy trucks and truck and others. This type of vehicle has a high power demand, so larger capacity lithium ion batteries or more advanced battery technologies (such as solid state batteries) are usually used. These batteries can not only provide higher energy density, but also maintain stable performance under high load.

II. Battery capacity

1. Light freight vehicle

the battery capacity of light freight vehicles is generally between 20kWh and 100kWh, and the specific capacity depends on the design and expected use of the vehicles. Smaller capacity can meet the needs of short-distance transportation in cities, and has advantages in charging time, which can complete charging in a short time.

2. Heavy freight cars

the battery capacity of heavy freight cars is usually between 100kWh and 400kWh or even higher. This is because heavy vehicles need to support long-time high-speed driving and high-load work, and larger battery capacity can provide longer endurance mileage to meet the needs of long-distance transportation.

III. Power output

1. Light freight vehicle

the power demand of light freight vehicles is relatively low, and the power output of motors is generally between 50kW and 150kW. The design of battery system needs to ensure fast acceleration and flexible control in urban traffic environment. Therefore, the battery system of light freight vehicles usually chooses the quick response battery configuration to meet this demand.

2. Heavy freight cars

heavy freight vehicles require higher power output, usually between 200kW and 600kW. Because heavy vehicles need large power support when starting and climbing, their battery system must be able to provide high instantaneous power. This requires the battery of heavy freight car to consider higher discharge capacity in design to meet the demand of its high load work.

IV. Cost

1. Light freight vehicle

the battery system of light freight cars is relatively small, and the cost is usually between tens of thousands of yuan and tens of thousands of yuan. Due to the rapid growth of the market demand for light freight vehicles, battery manufacturers are also continuously optimizing the production process, which gradually reduces the cost of light batteries.

2. Heavy freight cars

the battery cost of heavy freight cars is relatively high, usually ranging from several 100,000 yuan to millions of yuan. Due to the large capacity and high technical requirements of heavy batteries, the manufacturing cost also increases. In addition, the battery system of heavy freight vehicles needs higher standards in durability and safety, which further pushes up the cost.

1. Light freight vehicle

light freight vehicles usually adopt standard charging facilities, and the charging time is relatively short, usually charging within 1 to 4 hours. This kind of vehicle has a high frequency of use and can be charged in the distribution gap, thus reducing the dependence on charging facilities.

2. Heavy freight cars

the charging time of heavy freight cars is relatively long, which usually takes 4 to 8 hours or even longer. This is because its battery capacity is large and its charging power increases accordingly. In some cases, heavy freight vehicles may require dedicated charging facilities, such as fast charging stations, to improve charging efficiency. In addition, the maintenance of heavy batteries is also relatively complex, which requires regular inspection and maintenance to ensure its safety and performance.

VI. Application scenarios

1. Light freight vehicle

light freight vehicles are mainly used in urban distribution, express delivery service, short-distance transportation and other scenarios. This type of vehicle requires frequent start and stop and has high flexibility, so it is suitable for using fast charging and small capacity battery system.

2. Heavy freight cars

heavy freight vehicles are mostly used in long-distance transportation, heavy-load operations, and cargo transfer in logistics centers. This kind of vehicle needs long endurance and high power output to meet the transportation demand, so it is suitable to use large capacity and high performance battery system.

Light and heavy freight cars power Battery there are significant differences in the selection. These differences involve many aspects such as battery type, capacity, power output, cost, charging and maintenance. Understanding these differences helps manufacturers and users make more informed decisions when choosing suitable electric freight vehicles.
