269 2021-08-13



The GIS data collector adopts an industrial-grade three-proof design. The specially reinforced structural design can withstand a 1.5-meter drop to the concrete floor. The IP67 dustproof and waterproof standard can better meet the complex environmental requirements of your field operations. It adopts an integrated integrated design, which integrates multiple functions such as GPS, Windows system, digital camera, microphone, 3G communication, Bluetooth communication, mass storage, USB/RS232 port, SD card expansion, etc., to meet your diversified practical needs . Products are widely used in: land, electricity, forestry, environment, navigation, municipal and marine.

In order to meet the requirements of the GIS data collector field work environment, full-time work, low power consumption design and continuous work for more than 10 hours, etc., Panasonic long-life batteries are used for lithium battery cells, and two strings are combined to achieve customer-related requirements. Parameter requirements.

GIS data collector special lithium battery model: XL-7.4V-2.9Ah
Battery pack power: 22W

Battery pack size: 19*37*68mm

Protective function
Main chip: (Different solutions may choose different ICs)
Battery overcharge function: add a charger between P+ and P- to charge the battery. When the voltage is charged to 8.4±0.05V (can be designed according to requirements), the protection circuit will act to shut off the charging path to achieve overcharge protection
Battery over-discharge protection function: Connect a load between P+ and P- to discharge the battery. When the battery voltage drops to 6.0±0.1V (can be designed according to requirements), the protection circuit will act to shut off the discharge path to achieve over-discharge protection
Short-circuit protection function: When P+ and P- are short-circuited, the protection circuit will act quickly within 5-50uS to cut off the path to achieve short-circuit protection
Overcurrent protection function: When the voltage between B-terminal and P-terminal reaches (0.15±0.02V), the protection circuit will act quickly within 5-26ms to cut off the path to achieve overcurrent protection
