1. Intelligent detection robot battery design requirements:
According to customer requirements and specifications, design low-temperature battery packs for railway tracks, aircraft, and other testing equipment, and cooperate with safety protection circuits such as temperature protection to achieve a battery solution for batteries and equipment that operate in low-temperature harsh environments.
2. The specific parameter requirements are as follows:
1) Battery design requirements: lithium iron phosphate material 26650-14S12P/50Ah/51.2V
2) Structural design requirements: The requirements are less than 375x260x215mm, the appearance is exquisite, the overall is dustproof, waterproof, and shockproof, and the cold-rolled plate sprayed powder shell and aviation connector are used.
3) Circuit design requirements: working temperature: -20~+60℃, motor power: 1200W, rail car mileage: 30-40 kilometers, working 2-4 small four, charging 58.8V/5A.
3. Intelligent detection robot battery design scheme
1) Sheet metal powder sprayed shell and plastic battery holder: According to customer requirements, the design size meets the required sheet metal shell, and the surface is sprayed with powder to make the sub-black effect to meet the exquisite design requirements and meet the requirements of waterproof, dustproof and shockproof. Spot welding, with the plastic bracket to connect the battery cells, and the use of copper bus jumpers, to ensure the impedance and reliability of the overall battery pack.
2) Protection board(BMS):
3) Overcurrent protection chip (PTC): Mainly designed for secondary protection function. The PTC recoverable fuse has dual functions of overcurrent protection and automatic recovery. The PTC in the battery product can prevent the high-temperature discharge of the battery and the occurrence of unsafe high current.
4) Dedicated vacuum waterproof aviation plug: the external battery adopts a vacuum waterproof connection to meet customer waterproof requirements
5) LA26650-14S12P/50Ah/51.2V Lithium iron battery pack (low-temperature battery)
6) Battery arrangement scheme
