Why is Long Standby Vehicle GPS Tracker Afraid of Cold?
In the winter, especially in the cold regions, the automotive financial risk control practitioners often face the following problems: long standby GPS tracker does not go online, battery power drops too fast, etc., especially happens more obvious in the second or third year. Product disconnection is particularly pronounced in low-temperature environments.One of the main culprits that lead to long-time standby GPS tracker work abnormally in the winter is the battery that it uses.There are two main reasons why the battery in the tracker cannot work normally: First, the battery is very sensitive to temperature. The low temperature will cause the cell activity to decrease, the battery capacity to be attenuated, and the battery charge and discharge performance to decrease. The experimental report shows that the three kinds of equipment with different working currents will have different degrees of attenuation in the environment of -20 °C. Under the pulse discharge of 900 mA for 30 seconds, the power attenuation is even as high as 47%.Second, the battery type is not properly selected. The battery that is used in most of the long standby products on the market adopts digital (camera) or three- meter (water meter, electricity meter, gas meter) and other low-power battery solutions. This scheme designed without considering the battery's performance in extremely cold conditions, because the peak current of the digital camera or the three-meter is generally not more than 1.5A. The long standby vehicle GPS tracker combines the characteristics of communication and positioning, and its peak starting current can reach up to 3A. In the low-temperature state, when the battery capacity is sufficient, the device can start normally. However, as the battery capacity declines, if the low-temperature improved battery is not used, it is likely that the device cannot start up and go online normally from the second year.Vehicles are often exposed to the wind, sun, cold and heat, etc. It can be seen that the harsh external environment of the vehicle makes the ultra-long standby GPS tracker has high requirements for battery temperature adaptability. The use of digital or three-meter low-power batteries obviously cannot meet the complex and harsh environmental requirements.In order to solve the pain point of ultra-long standby hardware low-temperature application, concox has spent more than two years developing low-temperature multiplier industrial-grade lithium manganese battery for the current characteristics of ultra-long standby product，which can minimize the impact of temperature on the products.In a test environment of -20 ° C, the low-temperature improved battery and the digital low-power battery were compared in a multi-wheel machine, and the device was woken up every 10 minutes. It was found that the device using the low-temperature improved battery had a 30% higher average wake-up time than the other device. In addition, the equipment using the digital low-power battery can not completely discharge the battery power, and the power failure often occurs. The device using the low-temperature improved battery wakes up continuously and the battery power can be completely released.Since concox launch the first long standby GPS tracker, we have been adapting to the risk control needs of the automotive finance industry and actively promoting product innovation and industry development. We will still provide you with the best quality products and services, and continue to work, move forward, and innovate.More at: www.iconcox.comwww.iconcox.com/products/asset_series.html
