Any electric car that uses batteries needs a charging system to recharge the batteries. The charging system has two goals: To pump electricity into the batteries as quickly as the batteries will allow. To monitor the batteries and avoid damaging them during the charging process.
A filibuster is a parliamentary procedure where debate over a proposed piece of legislation is extended, allowing one or more members to delay or entirely prevent a vote on the proposal.
The Senate's cloture rule originally required a supermajority of two-thirds of all senators present and voting to be considered filibuster-proof. For example, if all 96 Senators voted on a cloture motion, 64 of those votes would have to be for cloture for it to pass; however if some Senators were absent and only 80 Senators voted on a cloture motion, only 54 would have to vote in favor.
