Details:
With the rapid development of intelligent control technology and sensing equipment, more and more robots are used in various fields. It is more and more common to use special robots to replace humans to work in special environments. Our intelligent lithium battery cleaning robot specially developed for solar photovoltaic power plants has strong weather resistance. The low temperature can reach -25 degrees and the high temperature can reach 65 degrees. It can adapt to the characteristics of large environmental temperature differences such as the Qinghai-Tibet Plateau. And it has the characteristics of high energy density, high voltage and high magnification. The same volume of power can provide a longer working time for the robot, adapt to various harsh environments, and solve the problem of continuous work in any weather.
1. Battery design requirements for 24V20Ah intelligent cleaning robot
According to the customer’s requirements and specifications and local conditions, we design a battery that meets environmental requirements and matches the host. Add battery heating module to the design. When the temperature exceeds -25 degrees, the device can be charged and discharged normally. It solves the shortcomings of poor charging safety of traditional lithium batteries below 0 degrees. Let the equipment run continuously in extremely harsh environments.
1) Battery shape requirements: use a square aluminum shell lithium phosphate battery (LP2770134-8S1P/20Ah/25.6V).
2) Structural design requirements: exquisite appearance, and the battery as a whole meets the requirements of waterproof, dustproof and shockproof. Battery compartment, 75*145*300mm
3) Circuit design requirements: 24V/20Ah, normal charging current 6A, normal working current 9A, instantaneous maximum working current 15A; conventional protection function of balanced circuit can be effectively compensated The difference between the battery cells during the battery use maximizes the battery life; the operating temperature is -25℃-60℃, and extra heating of the battery is required in low-temperature climates.
2. 24V20Ah intelligent cleaning robot battery design drawing
1) Powder coated metal shell. The metal shell is exquisitely designed according to customer requirements, and the surface is sprayed with black powder, which effectively protects the shell from oxidation and discoloration due to environmental influences. The design of the sealing strip meets the requirements of waterproof, dustproof and impact resistance. There are four special sockets on the shell for charging, discharging, temperature sensing and heating. The insulating layer uses an insulating material with a thickness of about 5 mm. The outer box has a handle design, which is convenient for temporary transportation and use; the top cover and panel can be flexibly disassembled, which is convenient for battery maintenance.
2) Protection board (PCM).
■ Protection board design: This solution uses high-precision BMS detection as the battery information acquisition unit, with overcharge, overdischarge, overcurrent, short circuit, high and low temperature protection functions, And can balance the voltage and current of the single battery. .
■ The design of the heating part. In order to ensure the heating effect, when the ambient temperature in the battery box reaches 0°C, the customer's charging terminal will detect the 0°C signal and delay (10 minutes) for heating. Its purpose is to ensure the consistency of the entire battery temperature.
3) Over-current protection chip (PTC): Mainly designed as a secondary protection function. The regenerative PTC fuse has the dual functions of overcurrent protection and automatic recovery. The PTC in battery products can prevent the occurrence of high-temperature battery discharge and dangerous high current.

3. Product features of 24V20Ah intelligent cleaning robot.
■ Long service life (the capacity is not less than 70 after 1000 cycles %).
■ Excellent working temperature (it can work stably for a long time under the temperature condition of -20℃+60℃).
■ Installing a battery detection unit in the battery can accurately detect the voltage, temperature, and capacity of the battery in real time, and transmit it to the main system in time through the communication system, which can completely improve Work safety of the product.
■ The shell of the battery pack is designed with sheet metal material, which has excellent impact resistance and high and low temperature resistance, effective flame retardancy, and high performance, which can ensure the battery pack under external impact Always maintain effective protection capabilities. It is equipped with a folding handle for carrying.
■ The battery unit has passed various safety tests of the People’s Republic of China’s automotive industry standard "Lithium-ion Battery QC/T743-2006 for Electric Vehicles", and all comply with the standards.
■ Easy to install and assemble (the design concept of the unit module makes the product installation flexible and reliable).
