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.
A small minority of senators, even a minority of one, can use the rules to delay or defeat objectionable legislation. The Senate's toleration of unlimited debate, in the form of the filibuster, has been its most notable difference from the House, whose rules favor the majority.
