EspañolThe performance of warehouse logistics trucks in extreme environments such as low and high temperatures is affected by many factors, including the vehicle's power system, cooling system, battery (if it is an electric truck), and the performance of on-board equipment. In order to ensure the stable operation of warehouse logistics trucks in these extreme environments, it is usually necessary to design and optimize the following aspects:
1. Performance and countermeasures in low temperature environments
The main challenges in low temperature environments include battery performance degradation, engine starting difficulties, lubricant thickening, and reduced tire grip.
Battery performance degradation: For electric warehouse logistics trucks, low temperatures have a particularly significant impact on batteries. Low temperatures can slow down the chemical reaction rate of batteries, thereby reducing their capacity and range. To address this problem, many electric trucks are equipped with battery heating systems (such as battery pack heaters) to improve the efficiency of batteries in low temperatures. In addition, batteries with stronger low temperature adaptability, such as lithium iron phosphate batteries, can provide better performance in low temperature environments.
Engine starting problems: For warehouse logistics trucks driven by internal combustion engines, low temperature environments can cause the engine oil to thicken, affecting the engine's starting and lubrication effects. To avoid this problem, you can use low-temperature oil specially designed for low-temperature environments, and equip it with a preheating system to ensure that the engine can start smoothly.
Lubrication system problems: Low temperatures can cause the liquid to thicken and affect the fluidity of the lubricant. Optimizing the lubrication system design, using lubricants suitable for low temperatures, and ensuring that the truck can start quickly and run smoothly in low temperatures are key.
Tire performance degradation: In low-temperature environments, rubber tires will harden, resulting in reduced grip. To cope with low-temperature environments, winter tires or low-temperature adaptive tires can be used, which have better low-temperature elasticity and can provide better traction.
Cooling system and air conditioning system: In low-temperature environments, the normal operation of the cooling system may be affected. It is necessary to ensure that the coolant does not freeze in low temperatures, and the air conditioning system can effectively regulate the temperature in the car to provide a comfortable driving environment.
2. Performance and countermeasures in high-temperature environments
The main challenges in high-temperature environments include engine overheating, battery overheating, poor heat dissipation, and excessive load on the air conditioning system.
Engine overheating: In high-temperature environments, the cooling system of the internal combustion engine may not be able to effectively dissipate heat due to high-temperature loads. To deal with this problem, a more efficient cooling system can be designed, and the power of the radiator and fan can be increased to ensure that the engine does not overheat at high temperatures. In addition, the use of high-temperature resistant engine coolant and the design of the engine hood with enhanced heat dissipation performance can also help improve heat dissipation capacity.
Battery overheating problem: For electric trucks, high temperatures will accelerate battery aging and reduce performance, especially when charging, the temperature of the battery may rise rapidly. To this end, electric trucks need to be equipped with efficient battery cooling systems, such as liquid cooling systems, to ensure the stable operation of batteries at high temperatures. At the same time, the battery management system (BMS) can monitor the battery temperature to avoid damage to the battery due to overheating.
Tire overheating: In a high temperature environment, the friction and temperature of the tire will increase, which may cause tire blowout or accelerated wear. Therefore, the use of high-temperature adaptable tires and the addition of a tire pressure monitoring system (TPMS) to monitor tire temperature and pressure in a timely manner are key measures to ensure truck safety.
Air conditioning system overload: High temperature environments place higher demands on the air conditioning system of warehouse logistics trucks. At high temperatures, the air conditioning system needs to provide strong cooling capacity to ensure a comfortable working environment in the vehicle. Designing a more efficient air conditioning system and selecting air conditioning compressors and refrigerants with better heat dissipation performance can effectively reduce the energy consumption and failure rate of the air conditioning system.
Vehicle interior and equipment: High temperature environment will accelerate the aging of vehicle interior parts and electronic equipment. In order to improve high temperature resistance, truck design needs to select high temperature resistant materials, such as heat-resistant plastics and metal materials, and equip electronic equipment and instruments with a suitable heat dissipation system.
3. The overall impact of extreme temperatures on warehouse logistics trucks
Temperature adaptability design: Warehouse logistics trucks need to take into account the adaptability to extreme temperatures when designing, including the anti-corrosion design of the vehicle body, insulation measures, and the high efficiency of the in-vehicle air conditioning system. Especially in the global logistics system, trucks usually move between different regions and need to adapt to environmental changes from tropical to cold regions.
Multi-function monitoring system: In order to ensure the safe operation of trucks in extreme temperatures, a real-time environmental monitoring system can be integrated to monitor key parameters such as temperature, humidity, tire pressure, liquid temperature, etc. through sensors, and provide real-time feedback to the driver or logistics control center to ensure that timely countermeasures can be taken when abnormal situations occur.
Strengthen the protection of drivers and goods: In extreme environments, the safety of warehouse logistics truck drivers and transported goods also needs to be considered. For example, in extremely cold environments, additional heating devices may be required inside the truck to ensure the comfort of the driver during long driving periods; and for the transported goods, especially temperature-sensitive goods (such as food, medicine, etc.), an on-board temperature control system may be required to maintain the appropriate transportation temperature.
The performance of warehouse logistics trucks in extreme environments such as low and high temperatures is affected by many factors, including battery and engine performance, cooling and lubrication systems, tires and air conditioning systems. To meet these challenges, manufacturers usually use efficient heating and cooling systems, high and low temperature resistant materials, intelligent monitoring systems and other means to ensure the stable operation and efficient operation of trucks in various environments. At the same time, the design needs to ensure the safety and comfort of drivers and goods to cope with extreme weather and environmental conditions.
