Electric forklifts are the future trend. Electric forklifts have less pollution, low noise, sensitive response, and comfortable driving environment, completely avoiding the disadvantages of large exhaust gas and noise pollution from internal combustion engines. Driven by the development ideas of "energy conservation and emission reduction, transformation and upgrading, quality and efficiency improvement" proposed in the national policy plan, the promotion and application of electric vehicles and new energy technologies such as electric drives, lithium batteries, and fuel cells in the field of industrial vehicles, It has played a very important role in promoting the development of global electric forklifts. The gradual replacement of internal combustion forklifts by electric forklifts is becoming a reality step by step and cannot be ignored! Electric forklift batteries will also have broad market development prospects and unlimited business opportunities!
As the heart of electric forklifts, lithium batteries have long life, fast charging, can be charged and used at any time, maintenance-free, and can be stored. These characteristics solve the shortcomings of lead-acid batteries. However, the safety, quality level, new knowledge such as BMS (battery management system), and maintenance of lithium batteries are beyond the capabilities of general leasing companies.
This time, we mainly introduce the precautions for purchasing and using forklift lithium batteries and exchange experiences with partners who are already engaged in, or are about to enter, the lithium battery rental industry.
First of all, the safety of lithium batteries is always top priority.
A fully charged lithium battery is a huge energy body. If it explodes or burns, the consequences will be disastrous. Relevant cases can be easily viewed on the Internet. Looking back at the forklift rental industry, lessors generally don’t know much about lithium batteries and often ignore important product safety aspects. Based on factors affecting security, we recommend the followin
We recommend using lithium iron phosphate (lifepo4 battery) and do not recommend leasing companies to use ternary lithium batteries. Because based on the nature of electrochemistry and battery principles, lithium iron phosphate is the safer among all types of lithium batteries. Ternary lithium pyrolyzes at around 200°C, while lifepo4 material decomposes at around 800°C. Moreover, the chemical reaction of ternary lithium is more violent, releasing oxygen molecules, and the electrolyte burns rapidly under the action of high temperature. In terms of safety accidents, as a popular saying in the industry goes, "Everything that catches fire is ternary lithium, and everything that smokes is lifepo4."
Secondly, quality and service.
There are many factors that affect quality. In order to facilitate understanding, here is a rough outline for forklift colleagues.
1. The advancement of production line design: With the advancement of technology and improvement of manufacturing capabilities, the energy density of lithium battery cells has increased year by year, and the overall quality level of the battery cells has also continued to improve. Some old production lines in the industry cannot achieve energy density, resulting in being removed from the catalog and unable to receive subsidies. This is an example.
2. Raw material quality level and stability. From a microscopic perspective, the particle size of the battery's positive and negative electrode materials, separator and electrolyte properties are all important to the quality of the battery core. There are systematic differences between different suppliers, so as a battery cell manufacturer, maintaining high performance and stability involves all aspects of production and management.
3. When the cells are matched into modules, the cells are screened to ensure consistency. The basic conditions for the "audition selection" of battery cell manufacturers are good, and small workshops without technical capabilities cannot carry out this operation.
4. R&D capabilities: Involving product development, BMS development, etc.
5. Technical service capabilities: affects after-sales service capabilities and timely response.
Finally, there is the service life:
For leasing companies, the service life is the length of the revenue period. Therefore, the longer the service life of the lithium battery, the more profits the lessor will make. Generally, the quality guarantee of lithium iron phosphate batteries in the automotive industry is 8 years or 200,000 kilometers. Mainstream domestic forklift manufacturers provide a life guarantee of 5 years and 10,000 hours.
There are also lithium batteries on the market with a 3-year warranty. Of course, some battery factories provide ternary lithium batteries, mainly for small lithium battery pallet trucks. The reason is that such trucks are usually scrapped in three years and do not need to be equipped with high-end batteries with longer life. However, as a lessor, you still hope that the battery can continue to be used, so it is not recommended for lessors to purchase ternary lithium lithium batteries.
Batteries are crucial as the power source for electric forklifts. The power requirements of a forklift are: strong power, continuous and stable supply. Currently, most electric forklifts use lead-acid batteries, but lead-acid batteries also have many criticisms: for example, acid batteries cannot be charged quickly, require maintenance and watering, and have a short service life. Lithium battery applications can be solved very well! With the continuous improvement of lithium batteries and the reduction of related production costs, more and more customers are gradually switching to lithium batteries!
Lithium-ion batteries have no routine maintenance. This means that much less money will be spent on labor as well. Watering, cleaning batteries and lifting compartments every day, in addition to replacing lead-acid batteries every shift, all require time and labor. These tasks are required on every lift, every shift, every day, whether you perform them in-house or outsource the work to a third-party company. By switching to lithium-ion power, workers will be able to focus on more important tasks and be significantly more productive every day.
