Maintenance of sanitation vehicles is a long-term commitment, especially during winter. In extremely low temperatures, failure to maintain the vehicles can affect their operational effectiveness and driving safety. Here are some points to note during winter use:
- Battery Maintenance:
In low winter temperatures, the battery capacity decreases. It is important to increase the charging frequency to prevent battery freezing. If the vehicle remains idle for a long time, regularly charge the battery, preferably once a month. To avoid excessive discharge and low battery levels, which can lead to power loss, rotate the battery power isolation switch to the OFF position or turn off the vehicle’s low-voltage power supply main switch.

- YIWEI electric sanitation vehicles are equipped with batteries that have a working temperature range of -30°C to 60°C. After undergoing multiple product tests, they have multiple protections against over-temperature, overcharging, over-discharging, and short circuits, ensuring stable performance and reliability. By following proper maintenance procedures, the battery’s lifespan can be extended.
- Trip Planning:
In winter, the range of pure electric vehicles can be affected by factors such as ambient temperature, road conditions, and driving habits. Battery discharge capacity weakens in low-temperature environments, and the use of air conditioning heating, battery self-heating, and reduced regenerative braking can increase power consumption. Therefore, when driving and operating pure electric sanitation vehicles in winter, plan your routes carefully and charge the battery promptly if the charge level is low. - Tire Maintenance:
The tire pressure of electric sanitation vehicles can change with temperature fluctuations. Generally, tire pressure is lower than normal in summer and slightly higher in winter. When measuring tire pressure in winter, wait for the tires to cool down after driving for a while and measure them at room temperature. Adjust the tire pressure accordingly based on the measurement. Also, remove any foreign objects from the tire tread to prevent tire damage.
- Preheating:
Proper preheating in cold weather can reduce the chemical reaction rate within the battery, thus minimizing battery loss. Preheating also helps avoid extreme temperature operation of the battery, extending its lifespan. Preheating time should be adjusted according to the local temperature, typically 30 seconds to 1 minute when around freezing and 1-5 minutes in temperatures below zero. When starting to drive, accelerate slowly for a few minutes to avoid immediate heavy acceleration. - Drainage Attention:
After using multifunctional dust suppression vehicles, water sprinklers, or sweepers, drain any remaining water from all parts to prevent freezing and damage to components. YIWEI’s self-developed 18-ton pure electric multifunctional dust suppression vehicle is equipped with an intelligent operating system, making winter vehicle use more efficient and convenient. It features a winter drainage function, where after completing operations, activating the working device and pressing a one-button drainage key in the cabin will automatically open and close all waterway valves in sequence, draining any remaining water. Manual drainage is required for sanitation vehicles without automatic drainage functionality.
Multiple drainage outlets should be available for effective drainage. Proper maintenance can extend the lifespan of sanitation vehicles in cold weather, reduce costs, and improve efficiency. YIWEI Automotive monitors the usage of each sold vehicle through a big data platform, providing timely aftersales support and worry-free service 24/7, 365 days a year. Vehicle maintenance is not only related to operating costs but also crucial for maintaining the quality of urban environmental sanitation. Timely inspection and repairs ensure efficient, safe, and smooth operation of sanitation operations in winter.
