With the rapid development of cold chain logistics, the stable operation of forklift inside cold storage is very important. As the power core of forklift, lead-acid battery faces many challenges in low temperature cold chain environment. With a series of innovative technologies and careful design, STILL forklift ensures the stable operation of lead-acid batteries in the cold chain environment, providing solid support for the efficient operation of cold chain logistics.

1. Unique battery insulation design

The temperature in the cold chain warehouse is often as low as -20 ℃ or even lower, and the low temperature has a great impact on the chemical reaction activity of the lead-acid battery. STILL forklift to deal with this problem, the lead-acid battery is equipped with a customized thermal cover. The thermal insulation cover adopts high-performance thermal insulation material, which can effectively prevent the external low temperature from passing into the battery. The actual test shows that in the cold storage environment of -18 ℃, the use of the thermal insulation cover can keep the internal temperature of the battery above 0℃, and create a relatively suitable temperature condition for the chemical reaction in the battery. At the same time, the insulation cover is also embedded in the intelligent temperature control system, when the battery temperature is lower than the set threshold, it will automatically start the heating wire to supplement the heat of the battery, ensure that the chemical reaction inside the battery continues to be stable, and avoid the battery capacity due to low temperature.

2. Optimized electrolyte formula

Electrolyte is the key medium for the chemical reaction of lead-acid battery, and its performance is easily affected at low temperature. STILL Forklift works with a professional battery development team to deeply optimize the electrolyte formulation of lead-acid batteries. On the basis of the traditional electrolyte, a special low-temperature anti-freezing additive is added, which can reduce the freezing point of the electrolyte, so that it is not easy to freeze in the extremely cold environment. At the same time, the additive can also improve the ionic conductivity of the electrolyte, promote the ion exchange between the positive and negative electrodes of the battery at low temperature, and maintain the normal charge and discharge performance of the battery. The experimental results show that the optimized electrolyte formula can still maintain more than 70% of the capacity of the battery under normal temperature at -25 ℃, which greatly improves the working efficiency of the lead-acid battery in the cold chain environment.

3. Accurate charge and discharge management system

In the cold chain environment, the charging and discharging process of lead-acid batteries needs to be more accurately controlled. STILL forklift is equipped with an advanced charge and discharge management system, which can monitor battery voltage, current, temperature and other parameters in real time. In the charging stage, the system will intelligently adjust the charging current and voltage according to the current state of the battery and the ambient temperature. For example, when the battery is in a low temperature state, the system will appropriately reduce the charging current to avoid excessive current causing the battery to heat too fast and damage the battery plate; As the battery temperature rises, the charging current is gradually increased to speed up the charging speed. During the discharge process, the system dynamically adjusts the battery output power according to the actual operating load of the forklift to ensure stable and efficient battery output. When the forklift truck is moving heavy objects uphill, the system automatically increases the battery output current to meet the demand for instantaneous high power. Under low load conditions such as flat road driving, the output current is reduced and the battery life is extended. Through this precise charge and discharge management, the service life of the lead-acid battery in the cold chain environment is effectively extended.

4.Enhanced battery structure design

The humidity of the cold chain environment is large, and the forklift may be shaken during the operation, which puts forward higher requirements for the structural stability of the lead-acid battery. The lead-acid battery of the forklift adopts a strengthened shell structure design, and the shell material is made of high-strength and corrosion-resistant engineering plastics, which can not only effectively resist the water vapor erosion in the humid environment, but also has excellent impact resistance. The internal plate of the battery is fixed in a special way, which reduces the risk of plate displacement and damage caused by forklift vibration by increasing the support structure and buffer materials. In the actual cold chain operation, after a long time of use, the lead-acid battery of STILL forklift truck is significantly better than the battery of ordinary design in terms of structural integrity, greatly reducing the battery failure caused by structural problems, and ensuring the continuous and stable operation of the forklift truck in the cold chain environment.
