Introduction Of Electric Wheelchair Battery For Medical Equipment Products:

With the development of medical technology and the continuous improvement of human material living standards, the portability of medical equipment functions and the homeization of product applications have become the development trend of the entire industry. This product uses high-performance lithium battery pack for power supply to meet the continuous, efficient and stable operation of the product.

Design Requirements For Smart Electric Wheelchair Battery:

Electric wheelchairs are convenient for people with inconvenient legs and feet to carry out mobile indoor and outdoor operations. Providing continuous, efficient, and stable mobile power has become the greatest guarantee for the normal operation of such equipment. The solution uses high-performance batteries to make the entire battery have the characteristics of high energy ratio, lightweight, small size, high cycle life, high safety, and high consistency. The power management solution uses a highly intelligent BMS battery management system to effectively manage battery safety and power.

Smart Electric Wheelchair Battery Design Scheme

1) Protection Board (PCM):
Mainly a protection circuit designed for rechargeable smart battery packs. Due to the chemical characteristics of the lithium battery itself, it is necessary to provide smart power calculation, overcharge, over-discharge, short circuit, overcurrent, and overtemperature, etc. Protective function. In order to avoid the danger of burning and explosion.
2) AFE/IC (Protection IC):
The main protection function chip of the design scheme, which performs online monitoring of overcharge, over-discharge, overcurrent, short circuit, and other functions of the cell. Make the batteries work in a safe, stable, and efficient range.
3) l Lithium iron phosphate battery:
32700 LiFePo4 cell (MANLY).
4) Field-effect tube (MOSFET):
MOSFET, which acts as a switch in the protection circuit, prevents the voltage at both ends of the load from increasing or decreasing, ensuring voltage stability.
5) Power management control chip (BQ2085):
A fully functional power meter with an analog-to-digital converter (ADC) for measuring voltage and temperature and an analog-to-digital converter for measuring current and charging sensing. The power meter has a microprocessor that is responsible for performing power detection and can provide information such as the remaining power state (Remaining State of Capacity). The BQ2085 chip also provides the remaining run time (Run Time to Empty). The host can query this information to the fuel gauge at any time, and notify the user of the battery information. The use of the fuel gauge is very convenient, allowing users to grasp the battery power at any time.
6) Battery pack packaging:
PVC shell.
