Fresh cold chain logistics park, low temperature stability operation plan for lithium battery forklift

The low-temperature storage environment of the fresh cold chain logistics park places strict requirements on the on-site operation equipment. As the core handling tool, the operation stability of the lithium-ion forklift at low temperature directly affects the turnover efficiency and quality assurance of fresh goods.

The optimization of battery low temperature protection is the core link of the stable operation of lithium battery forklifts. Low temperature environment will lead to the decline of lithium battery activity, battery life attenuation, and even abnormal charging and discharging. To this end, the thermal insulation protection structure can be customized for the battery module, and the external low temperature invasion can be blocked by thermal insulation materials to maintain the internal temperature stability of the battery. At the same time, it is equipped with an intelligent preheating system, which preheats the battery in a low power consumption mode before operation, so that it reaches a suitable working temperature before starting the operation. With the optimized low temperature algorithm of the battery management system, the charging and discharging strategy can be adjusted in real time to avoid the occurrence of excessive discharge or insufficient charging.

The low temperature adaptation of the whole vehicle system needs to cover the performance adjustment of the core components. The hydraulic system is prone to get stuck due to the decrease in the fluidity of the hydraulic oil in the low temperature environment, and the special hydraulic oil for low temperature resistance can be replaced to ensure that the lubrication and transmission effect can still be maintained at low temperature, and the mechanical wear can be reduced. The electronic control system needs to optimize the circuit layout and add a low temperature protective layer to avoid damage to the circuit due to low temperature brittle cracking. At the same time, the output parameters of the motor are adjusted to maintain a stable power output in the low temperature environment to meet the handling needs of fresh goods of different weights.

Daily operation and maintenance management is the key to ensuring long-term stable operation. Establish a regular inspection mechanism to carry out performance inspections in low temperature environments for core components such as lithium batteries, hydraulic systems, and electronic control systems, and promptly investigate potential failure hazards; set up multi-regional temperature monitoring points in the logistics park to grasp the temperature changes in the operation area in real time, adjust the forklift operation rhythm according to the temperature situation, and appropriately shorten the continuous operation time during the extreme low temperature period, so that the equipment can be properly rested; at the same time, strengthen the training of operators to make them proficient in the operation points and emergency treatment methods of forklifts in low temperature environments, and improve the standardization of operations.

Through the above multi-dimensional scheme optimization, the operation stability of lithium-ion forklifts in the low temperature environment of fresh cold chain logistics park can be effectively improved, the equipment failure rate can be reduced, and reliable support can be provided for the efficient turnover and quality assurance of fresh goods.
