5.8G Highway traffic composite card battery matching scheme
In order to realize highway multi-path identification and improve the purpose of accurate charging, the highway expressway card began trial operation in 2009. Since the research on the 5.8GHZ transmission frequency band was not mature enough at the time, the transmission frequency band of 433MHZ was adopted, and the lithium manganese button battery CR3032 was the most suitable battery solution at that time.
With the research and exploration of the 5.8GHZ frequency band in recent years, it is found that upgrading the 433MHZ frequency band to the 5.8GHZ frequency band is the best solution for the compatibility of MTC users and ETC users.
As a supporting power source for 433MHZ composite card, lithium-manganese button battery is no longer suitable for frequency band upgrade. Lijia Technology has optimized and improved the positive electrode and electrolyte based on the original design, and the CRW ultra-high power battery has been developed. The current working power is enhanced by ten times and the operating temperature is greatly expanded. Through data comparison and analysis, CRW battery can meet the working parameters of 5.8GHZ composite card. The specific parameters of the battery can be found in the product product display new product column of the company website.
