Is Electric armour feasible with current technology?

I read about electric armor (also known as dynamic armor or electric reactive armor) that can protect armored vehicles from shaped charges of anti-tank weapons and I want to know if its feasible today.
according to wikipedia:
[Moderator: please don't do this without a link. The link is The link is https://en.wikipedia.org/wiki/Dynamic_Armor]
"Electrically charged armour is a recent development in the United Kingdom by the Defence Science and Technology Laboratory. A vehicle is fitted with two thin shells, separated by insulating material. The outer shell holds an enormous electric charge, while the inner shell is at ground. If an incoming HEAT jet needle of a conductive metal, like copper, penetrates both shells, it forms a bridge between them, and the electrical energy discharges rapidly through the jet, disrupting it. Trials have so far been promising, and it is hoped that improved systems could protect against kinetic energy penetrators"

what are the challenges in making something like this and putting it on something like a tank?. the electric armor can(in theory at least) work more than once at one spot or it get useless after the first penetration?. the wiki article mentioned successful tirals but I didn't managed to find much information about electric armor other than this article(link) from 15 years ago but is to technical for me.

Did you read the references from the Wikipedia article? One of them says.

https://www.economist.com/technology-quarterly/2011/06/02/the-armour-strikes-back said:
Antoine Vincent, in charge of electric armour for the European Defence Agency (EDA), says it has tested well against RPGs. A study by BMT Defence Services, a British firm, notes that electric armour, being lightweight, makes it easier to airlift vehicles. Even so, neither BMT nor the EDA think the technology will be deployed soon. It has proven difficult to rearm the metal plates from batteries fast enough to zap the second charge of a tandem warhead. Some of the power-management technologies being developed for electric vehicles may help on that front. But, says Mr Vincent, electric armour still does not deliver enough electricity to fry the metal in many kinetic-energy projectiles, which destroy armour with their impact. An RPG warhead may eject a copper spike weighing several hundred grams. Kinetic-energy projectiles can weigh several kilograms.

the website asks you to register/subscribe and pay for watching some of its content like that article so I didn't read it.
so it can work for multiple hits on the same spot as long as it can "charge" the metal plates fast enough?. what kind of technology developed for electric vehicles can help here?.

Not the website I linked.

Re-read. It can only stop lightweight warheads such as RPG. It won't stop more massive ones such a round fired by another tank.

I am talking about HEAT warheads and not kinetic penetrators used by tanks.
I am using your link and got only part of the article with "register to read this article in full" at the end. did you registered in that site?.

I did not read it in full. I got the quote from the fraction that was open.

this is all what I see and I used copy past with the link you provided... maybe you registered to this site once and forgot about it?.

can you tell me what type of "power-management technologies being developed for electric vehicles" the article talked about?.

Not specifically, but my guess is improved batteries and improved battery charging circuits.

The same power sources considered for rail guns have also been considered for this idea. In both cases, in my own experience, the idea was to have very how power generator spinning at high speed that is shorted to produce the required currents by extracting energy from the rotating mass.
