In today's fast-developing logistics industry, electric forklift has gradually become the new favourite in the market with its environmental protection and high efficiency. The core of electric forklift - ‘three electric’ technology, namely battery, motor, electronic control technology, is the key to its outstanding performance. In this paper, we will discuss the latest progress of electric forklift ‘three electric’ technology, and reveal how these technologies are to achieve electric forklift range increase of 30%. First, the innovation of power battery technology 1. The application of high-performance lithium batteries: In recent years, with the continuous progress of lithium-ion battery technology, its application in electric forklift trucks is

also increasingly widespread. Compared with traditional lead-acid batteries, lithium batteries have higher energy density and longer cycle life. This means that in the same volume and weight, lithium batteries are able to store more power, thus significantly extending the range of electric forklifts. For example, some high-end electric forklift brands have adopted high energy density Li-ion battery packs, enabling forklifts to travel longer distances on a single charge.  2. Intelligent Battery Management System: In addition to the performance enhancement of the battery itself, intelligent BMS also plays an important role in the range enhancement of electric forklift trucks, which is capable of real-time monitoring of the battery's status, including key parameters such as voltage, current, temperature, etc., and controlling and managing the battery charging and discharging according to these data. Through precise control strategies, the BMS can ensure that the battery operates under optimal working conditions, thus improving the efficiency and life of the battery. At the same time, the BMS is also able to predict the battery's remaining power and drivable mileage, providing users with more accurate range information .   Optimisation of drive motor technology 1. High-efficiency permanent magnet synchronous motor: In the drive system of electric forklift, the motor is a crucial part. In recent years, high-efficiency permanent magnet synchronous motors have been widely used in the field of electric forklift due to their excellent performance. Permanent magnet synchronous motors are characterised by high power density, high efficiency and low energy consumption, which can provide strong power while reducing energy consumption. By adopting advanced motor design and manufacturing process, electric forklift manufacturers have successfully improved the efficiency and power density of motors, which further extends the range of forklifts .  2. Innovation of motor control technology: In addition to the improvement of the performance of the motor itself, the continuous innovation of motor control technology is also the key to achieve the improvement of electric forklift range. Modern electric forklift trucks generally adopt advanced motor control algorithms and inverter technology, which can dynamically adjust the motor speed and torque output according to the actual working conditions of forklift trucks. This intelligent control not only improves the power performance and operational efficiency of the forklift, but also effectively reduces energy consumption and wear and tear. At the same time, by precisely controlling the working state of the motor, it can also reduce unnecessary energy loss and further improve the range of the forklift.   Integration and innovation of vehicle electronic control technology 1. Upgrading of vehicle controller: Vehicle Control Unit (VCU), as the brain of electric forklift, is responsible for coordinating and managing the work of various components. With the continuous development of electric forklift technology, the function of VCU is also constantly upgraded and improved. Modern electric forklift generally adopts high-performance VCU, with stronger data processing capability and faster response speed. Through the precise control and optimal management of the battery, motor, transmission system and other components, the VCU can ensure that the forklift truck can maintain the best working condition and the highest energy efficiency ratio under various working conditions.  2. Application of Energy Recovery Technology: In order to further improve the range of electric forklift trucks, many manufacturers have started to introduce energy recovery technology. This technology can convert kinetic energy into electric energy during braking or deceleration and store it back in the battery, thus realising energy recycling. Through the application of energy recovery system, electric forklift trucks can reduce energy consumption and heat emission to a certain extent, and improve the overall energy efficiency and range.   To sum up, the progress of electric forklift's ‘three electrics’ technology is the key to achieve its range increase of 30%. By adopting high-performance lithium batteries, high-efficiency permanent magnet synchronous motors, advanced vehicle electronic control technology and energy recovery technology, electric forklift manufacturers have successfully improved the range and energy efficiency of forklifts. In the future, with the continuous development of science and technology, we have reason to believe that electric forklifts will play a greater role in more fields.
