19.2V F13000mAh Battery Design Solution of Track Detector

As Ni-MH battery has outstanding advantages in working in low temperature environment, many portable products in military field estimate the remaining capacity by voltage measured value, but the relationship of voltage and remaining capacity will change with temperature and aging state. Therefore, the error rate of this method may be up to 50%. As the product requirement being more and more severe, the battery design needs more accurate solution. Measure the charging or consuming capacity by intelligent capacity survey meter IC, and then it can provide more precise capacity measurement in wide power supply application.

Battery design solution of detector:

1）Aluminum housing and aluminum holder: based on customer’s requirements of aluminum housing, it meets the requirements of waterproof, shock resistance and heat dissipation under large current.

2）Intelligent capacity guard plate (PCM): adopt SBS intelligent battery management system, make use of advanced capacity measurement principle to calculate battery capacity at any time, send the capacity information to host machine by SMBUS, and provide protective function for rechargeable battery pack it needs protective functions of overcharging, over discharging, short circuit, over current and over temperature so as to avoid combustion and explosion.

3）LED capacity display panel: LED capacity display light shows the battery capacity by intelligent voltmeter with 20% electricity proportion so as to be efficient and visual for customer’s application.

4）Overcurrent protection (PTC): it is designed for secondary protective function. Restorable PTC fuse has dual functions of overcurrent protection and self-recovery. PTC of the product can prevent high-temperature discharging and unsafe large current.
