Q1

Why did the Joker steal the battery from Gotham's power plant?

The Joker needed the powerful battery from the atomic power plant to power his city-wide scheme.

Q2

How did the Joker take control of all electronics in Gotham?

After stealing Professor Ivo's artificial intelligence and combining it with the battery, the Joker deployed a citywide virus that seized control of every electronic system in Gotham. This included traffic lights, security cameras, and most importantly, Cyborg, whose systems were compromised and forced to help execute the Joker's plan. The Joker used this total technological control to proclaim himself mayor and hold the city hostage.
