Finding and Killing Receive Noise. Obviously there is an almost infinite marketplace full of devices that may generate noise and I can only afford to buy a few here and there. If you have something you want tested, I would be happy to do so; contact me and ship it over. Note that the primary emphasis here is on the HF bands, 1.

Its help for amateurs also extends into helping industry resolve interference problems, from the creation of good industry standards to the development of case-by-case solutions should problems still occur. The working state of the battery is very important to the safety of an EV. Online estimation of the state of charge SOC is essential in obtaining the battery working conditions.
In order to achieve an accurate estimation of the SOC, the battery model should be adjustable when the battery is aged. A combined battery model is used to depict the relationship between the open circuit voltage OCV and the SOC of the battery. The main battery model parameter for estimation is the internal resistance and it is jointly estimated with the SOC online.
Experimental results show that the SPKF based joint estimation method is effective. Zhiwei received the B.
