7.4V 4400mAh li-ion battery pack for intelligent Robot

2018-09-13

This intelligent Robot battery is suitable for Robert application and has come out on the market. Fello Tech adopts developed lithium ion battery technology on the Robot battery schemes, which makes the battery have outstanding endurance capability. Compared to other brands, Fello Tech Robot battery contains characters of high capacity, stable charging and discharging performance, good cycle life, nice high-temperature & low-temperature performance and strong shock resistance.


Design requirements:


Ⅰ. The battery design requirements of Intellegient Robot


According to the requirements of product specification and customers, the battery design of Intelligent Robot System needs to assort with the host machine, and integrate high safety performance, good charging and discharging performance and outstanding long-term application reliability into the solutions.


Ⅱ. The battery design scheme of BeiDou Navigation Satellite System:


1)Guard plate (PCM): it is a protective circuit designed for rechargeable high capacity battery pack, which provides the battery with protective functions of overcharging, over-discharging, short circuit, overcurrent and over-temperature.


2)Protection IC: the chip has protective function in the design scheme. It can monitor the cell online at any time, so that the cell can work under safe, stable and efficient circumstance. TI BQ3060 intelligent chip has protective parameter of custom programming (Internal Integration FAE) communicating with host machine of navigator for accurate power display, temperature display, battery lifespan indication and charging &discharging status.


3)FUSE: it is a design for Secondary protective function. Fuse has overcurrent protective function. Apply fuse in battery can prevent insecure event of charging and discharging under large current.


4)Lithium ion battery: 18650/4400mAh/7.4V lithium ion battery


5)MOSFET: it works as a switch in the protective circuit.


6)Encapsulation of battery pack: the manufacture of external packing depends on customers’ requirements.


7)Anti-shock property: fill the interior battery by epoxy resin or neutral silica gel, which has resulted in advanced anti-shock property.
