Electric forklift wireless charging technology

Now the whole world is paying attention to the development of intelligence and unmanned operations. The transformation of the manufacturing and logistics transportation industries from automation to digitization, and then to intelligence and unmanned operations is the general trend. At the same time, the number of labor forces has decreased in recent years and the process of unmanned industry has accelerated. Unmanned forklifts occupy a very important position in the cargo handling and transportation process and will usher in huge development.

The common charging method for traditional electric forklifts is to connect the battery cable to the plug of the electric forklift cable for charging. There are also some unmanned forklifts that use automatic charging, but rely on exposed electrodes for contact charging. However, these charging methods have many industry pain points in practical applications: manual plugging and unplugging are very difficult; on-site workers can easily cause damage to the charging plug during use, causing charging failures and affecting the use of forklifts; if the charger is not plugged in properly, the connector will be damaged due to excessive resistance; it must be wiped frequently and kept dry and clean , otherwise it will corrode the electrodes and connecting strips, and then damage the battery; avoid stopping midway during the charging process, and must charge until the charger shows that it is full, which limits the handling time of the forklift; it is necessary to configure multiple spare batteries to ensure that the normal handling work of the forklift is not affected, which increases capital investment; manual plug-in charging and regular inspection and maintenance are required. In addition, in some clean usage environments with dangerous gases, arcing, sparking, etc. during charging are also strictly prohibited.

In recent years,wireless charging Technology has achieved many applications and developments in fields such as mobile phones and wearable devices. These application scenarios usually have relatively small output power (several watts to more than ten watts) and short working distance (less than 1CM).Electric vehicle forklift wireless charging It has the characteristics of large charging power (several kilowatts to more than ten kilowatts), long working distance, low voltage and high current output, etc.Wireless charging for electric forks It is very difficult to achieve high efficiency and small size of the machine.Electric forklift wireless charging It uses the principle of magnetic field coupling resonance to achieve high-efficiency energy transmission. It can transmit electric energy to electric forklifts without plugging, contacting or approaching.wireless charging The technology has subverted the traditional charging method of electric forklifts. As the technology becomes increasingly mature, it may replace the traditional wired charging method in the future.

Electric unmanned forklift wireless charging The system consists of four parts: transmitting end, transmitting coil, receiving end, and receiving coil. The receiving end and receiving coil are installed inside the forklift, and the transmitting end and transmitting coil are integrated into a wireless charger. When an electric forklift equipped with a receiving end and a receiving coil wireless charging Just bring the machine close to each other and make the two coils face each other.automatic charging。

Electric forklift wireless charging Unique technical advantages: no exposed electrodes, close wireless charging Just in time Electric forklift automatic charging. There is no need for precise alignment, no electrode oxidation and staining, and no charging failure problems caused by poor electrode contact. The docking success rate of electric forklifts and wireless charging piles can reach 100%, which greatly saves the cost of manual maintenance.Electric unmanned forklift wireless charging The process is safe and reliable, there is no spark when charging with high current, and it is safe and does not leak electricity. Electric forklifts can be parked, charged and taken on the go, effectively utilizing fragmented time for charging, which greatly improves the operating efficiency of electric forklifts.

At present, domestic and foreign Electric forklift wireless charging There are many manufacturers and companies. The mainstream wireless charging manufacturers includeLuyu Energy, ZTE, etc. The annual sales volume of forklifts nationwide is more than 500,000 units, among which autonomous navigation unmanned forklifts account for an increasing proportion of electric forklifts. At the same time, the COVID-19 epidemic has made many manufacturers realize the importance of automation and intelligence, and the demand for unmanned operations has been greatly stimulated. As an indispensable part of the normal operation of electric forklifts, the charging method under unmanned conditions will inevitably make huge reforms. Wireless charging will definitely inject huge impetus into the development of intelligent and unmanned processes.
