Introduction to GPS
Navigation Power Supply Battery Types and Performance
Navigation products currently on the market include handheld, vehicle, GPS mobile phone, PDA with GPS, There are several types of GPS modules, no matter what type of navigation product it is, the power supply issue is one of the important factors to consider when purchasing.
And among these types of GPS devices, the one that requires the least power supply is probably the car GPS. These products can generally be powered by the car power supply, so there is no need to worry about the battery life when driving. However, with the continuous intervention of many additional functions, when the car GPS can be used as a portable audio and video device at the same time, the factor of power is much more important than ever. There is no need to say much about the other types of power supply requirements, and the length of battery life directly affects the use of the machine.
The difference in function is shrinking day by day, and the product functions are becoming more and more complete. Looking at the power supply methods of these different types of navigation products, there are nothing more than the following four.
Powered by lithium batteries
The earliest lithium batteries came from the great inventor Edison. In 1992, Sony successfully developed lithium-ion batteries. After that, we have widely used it in portable electronic devices such as mobile phones and notebook computers. This type of battery not only prolongs the use time, but also greatly reduces environmental pollution compared with nickel-chromium batteries because lithium-ion batteries do not contain heavy metal chromium. Therefore, lithium batteries can be said to be the preferred power supply device for electronic products at present.
GPS mobile phones, PDAs with GPS, and a part of vehicle GPS and GPGPS navigation equipment knowledge introduction-features-category: mainly introduces the performance and efficacy of GPS navigation equipment, as well as the use of lithium batteries for GPS navigation Introduction of power supply types such as power supply, dry battery power supply, solar power supply, and vehicle power supply. The S modules all use lithium batteries. The least amount of lithium battery used in these devices is only a few hundred mAh, and the big guys with 7-inch screens like the Shinco GD-70C even have as much as 3800 mAh, but most products are still concentrated in the range of 1000-2000 mAh.
The most inconvenient thing about using this power supply method is that once the power runs out, it is difficult to find a replacement unless you have a second battery on hand. We are fortunate that the lithium batteries of many GPS modules can be used with some Nokia batteries. If you happen to have a Nokia mobile phone, you can pay attention to it when you buy it.
Dry battery power supply
Dry cell battery was invented many years earlier than lithium battery, and we began to use this power supply method in the 18th century. It has been used to this day, and it can be seen that it still has its own advantages. And the most obvious is that it is very convenient to obtain dry batteries, and just walk into a convenience store to bring your GPS back to life.
At present, the vast majority of GPS products powered by this method are those professional GPS handsets, and there are already a few car GPS and GPS modules. If it is a product powered by dry batteries, you can bring more dry batteries when you go out for emergencies on the road. This is probably its biggest advantage over lithium batteries. However, dry batteries are large and heavy, which is a fact that has to be faced.
Solar power supply
Solar energy can be said to be a new type of completely non-polluting energy that humans are using and actively developing, so the use of solar power is also the general trend . In order to solve the problem of battery life when traveling, the GPS module can be said to be the first to use the solar energy function.
Using this type of power supply, the GPS module represented by the Gurry Sunbird is equipped with a large solar panel in addition to the lithium battery in the fuselage to convert light energy into electrical energy. At present, there are very few products using this power supply method. Although the problem of battery life has been solved, this power supply method is not stable, which will also affect the use effect of the product.
Vehicle power supply
Vehicle power supply is basically designed for in-vehicle GPS products. Guaranteed solution. However, not all products can use car power supply, and there are more and more opportunities for GPS products to be used elsewhere, so it is not always possible to use the car power supply to power your navigation equipment.
In addition, these GPS products can also be used when using DC power supply and USB cable for charging, here we do not attribute them to the scope of ‘power supply’. Therefore, the power supply methods of navigation products are nothing more than the above four types. Don’t forget to consider them when purchasing GPS products.
