In the Nevada desert, in the middle of the wasteland, in the land of mustangs, speed records, unique finds, petroglyphs, hot springs, and great discoveries, there is a battery storage HE3DA 20KWh, which celebrated its 2nd anniversary in mid-October.
As on the first anniversary, we came to see Camp David, which drives this store. Camp David is also the second oldest falcon farm in the USA. See: http://www.skyoutfalcons.com/

The project was created in collaboration with the company HE3DA and the University of Nevada in Las Vegas. The two parties have signed a cooperation and strategic partnership agreement. In this way, HE3DA has supported a world-renowned study of boiling water surviving organisms. The study was also financially supported by NASA, which brought about the unexpected discovery of the third genome of these Extremophiles.
The local media also informed about the project several times. The research was even described by the famous documentary filmmaker David Attenborough.

Only On 2: Lithium Batteries Help To Monitor Microbes in Gerlach Hot Springs
HE3DA has been given a unique opportunity to verify the function of its batteries in really extreme conditions, where temperatures vary by up to 30 ° C between day and night. In winter it is up to -20 ° C, in summer 40 ° C is no exception. There is a high concentration of alkali salts and superfine dust in the air. The ranch is supplied with energy inside this off-grid system by combined sources from 3 solar circuits, namely wind power plants, a natural gas unit, and geothermal energy. Charging currents can reach up to 250A and similarly the discharge currents are at a similar level.
In addition, the repository is a completely brushed system without a BMS, and its behavior is monitored by an electronic monitoring system, which, however, cannot in any way affect the operation of the batteries. So far, the electronic components of this system have proven to be the only faulty part. In the environment of alkaline salts, electrical contacts oxidize very quickly, and even expensive electronics cannot withstand these extreme conditions. The thermometers were changing for the fourth time, the voltage sensors had to be changed twice and only a perfect connection created a more reliable system. Logic circuits also suffer in this environment, which Adbitech has been improving for two years in cooperation with HE3DA. The control logic circuits were also replaced three times.
On the contrary, HE3DA batteries have shown maximum robustness and have been supplying electricity to the Camp David Ranch for two years now. Once a year there is a service where all the articles are compared to the same level. This service replaces the complex battery and electronic control systems (BMS-battery management system).
This storage, which can fit on one pallet and can be dropped by plane practically anywhere, aims to demonstrate the perfect usability of such a simplified system, which is suitable for geological, medical, or military missions in difficult conditions. It continuously supplies electricity and survives electromagnetic pulses that can completely shut down any electronics.
In 2018, HE3DA batteries replaced lead cells with a total capacity of almost 40 KWh. Since then, it has been running continuously, without any electronic control systems. They reliably cover energy consumption at a time when solar panels and other sources do not produce electricity.
The expected lifespan of the repository in these extreme conditions is 20 years. In contrast, lead cells had a lifespan of only 2-3 years.
