EMP Surge Protection Device for Vehicles

 

Why did I make the Surge Protection Device?

I became aware of the threat in 2007 and started thinking about it in 2013. I took some measures back then but the world situation did not dictate an immediate threat. Now the world situation is serious. To quote Senator Ron Johnson in reference to an Electro Magnetic Pulse EMP or Geomagnetic disturbance GMD "There is 100% certainty that this will happen some time in our future." When Russia invaded Ukraine I scrambled to make something to put on our many tractors that would be affordable. Compare my $60 device with EMP Shield's $400 device. 

How does it work? 

When the surge protection device detects a voltage spike it creates a dead short across the battery terminals pulling electricity away from the electronics to the battery where the battery absorbs the charge. This device is good for multiple surges. It is not a one time use device.

How do I know it will work?

Based on the math below and the electric component manufacturers specs, show it will work. I also tested it. As below I expect a .5 joule surge on a vehicle. I took a .7 joule cattle electric fencer and hooked it to a battery powered radio with a surge protection device. I turned them both on and the radio kept playing while it was getting pulsed with thousands of volts.

About the Surge Protection Device 

• Speed: Military specs for emp protection devices are that they react to voltage spikes in less than 5000 picoseconds. This device reacts in 1 picosecond. 

• Power: Typical emp yield is 50kv/m2 but a super emp weapon yield is 200kv/m2 or 26.4MW. Energy = Watts x seconds. 26.4mw x 17ns = .46 joules of surge power created by emp on a vehicle. This device is capable of handling 5 joules of energy which is 10 times more than what is expected.

How do you install it on a vehicle?

First before you get your device know what size rings you need based on your battery clamp bolt size. I am making 1/4 and 3/8. To install undo the nut on each battery cable clamp and put the red wire to the positive and the black wire to the negative. Use the zip tie to anchor the device to a near by wiring harness.
