The core characteristics of large capacity robot power lithium battery
1. High energy density
Large-capacity lithium batteries need to have a high energy density to meet the long-term operation needs of robots. For example, Langevwe‘s 24V200Ah lithium iron phosphate battery significantly reduces battery weight and volume through a high energy density design for industrial and service robots. Some manufacturers (such as Ningde Times) are developing semi-solid batteries with higher energy density, which can reach 500Wh/kg, and may be used in the field of humanoid robots in the future.
2. Security and stability
Due to its stable chemical properties, lithium iron phosphate batteries are safer under extreme conditions such as overcharge, high temperature or short circuit, and are suitable for robot applications in complex environments. In addition, some battery packs (such as Changhong Power‘s 21NCM35 semi-solid battery) further enhance safety through explosion-proof design and multiple protection mechanisms (overcharge, overdischarge, temperature protection).
3. Long cycle life and fast charging
The cycle life of high-quality power lithium batteries generally exceeds 2000 times (lithium iron phosphate batteries) or 800 times (some ternary lithium batteries), supporting frequent charge and discharge needs. Fast charging technology is also widely used, such as Langkawi battery support short time full charge, improve the efficiency of the robot.
Typical application scenarios and product examples:
1. Industrial robots
24V200Ah lithium iron phosphate battery: suitable for AGV cars, industrial production line robots, to provide stable power and long endurance.
2. Humanoid robots
Tesla Optimus: A 2.3kWh, 52V cylindrical battery pack combined with a high-nickel terpolymer increases energy density.
3. Special robots
48V fire robot special battery: Through RS485 communication and high temperature protection design, to meet the requirements of high temperature and high pressure fire protection scenarios.
Technology trends and challenges:
1. The potential of solid-state batteries
All-solid-state batteries are considered to be the key technology to improve battery life in the future. Gac‘s GoMate robot can run for six hours on a solid-state battery, but its mass production still takes time.
2. Modular and lightweight design
Battery manufacturers, such as Far East Battery, have introduced modular solutions that flexibly adapt to different load and scenario requirements, while reducing energy consumption through lightweight materials.
3. Optimization of battery management system
Zhongying Electronics and other enterprises develop special lithium battery management chips to monitor battery status in real time and optimize charge and discharge efficiency to extend battery life.
In SUMMARY:
The core requirements for high-capacity robot-powered lithium batteries focus on high energy density, safety, long life, and fast charging. Future technologies such as solid-state batteries, modular designs and intelligent BMS systems will further drive the industry. The current mainstream products include lithium iron phosphate and ternary lithium batteries, manufacturers need to combine robot application scenarios (industrial, service, special) to provide customized solutions.
