Foreword: rise gradually as living standard, sundily lamps and lanterns except should satisfy illume demand outside, also should accord with adornment and beautify the effect of bedroom, accordingly, accelerated the development that lamps and lanterns lamp acts the role of industry
Since the development of lamps at home and abroad, including mobile lighting equipment, emergency lighting equipment, solar lighting equipment, etc., our company has also done the development, test and mass production of the lamp battery, which is suitable for all kinds of DC lighting equipment, and has been introduced to the market. Our company's lamp battery scheme uses mature lithium battery technology, battery pack safety performance, strong endurance. Compared with domestic lithium battery pack, it has the characteristics of high capacity, good consistency, high precision and good stability of protection circuit, stable charging-discharge performance, good cycle life, good high and low temperature performance and strong seismic resistance.

Design requirements:

One, lamp battery design requirements:
According to product specifications and customer requirements, the battery pack is designed to integrate high safety performance, good charge and discharge performance, and outstanding long-term reliability into the solution.
Ii. Battery design Scheme:
1) Protection plate (PCM) : it is mainly a protection line designed for rechargeable high-capacity battery pack, which can provide protection functions such as overcharge, overdischarge, short circuit, overcurrent and temperature sampling for lithium battery.
2) Protection IC: the main Protection function chip of the design scheme. High-precision IC program is adopted to monitor the function of the cell, so that the cell can work in a safe, stable and efficient range. The main control IC chip has fixed protection parameters matching with 18650 cell, which can always detect the voltage of each battery.
3) Lithium battery: 18650/2600mah /3.7V lithium battery
4) Field effect tube (MOSFET) : MOSFET tube, which plays a switching role in the protection circuit.
5) Battery pack packaging: the outer packaging can be made according to customer requirements.
6) Seismic performance: the battery pack is wrapped in PVC. Good seismic performance.
