1. The electic cars are expected to account for XX of the cars by 2020, depending on the oil prices. This increase would bring about great stress to nation's electricity. 2. One common way to encounter such problem is to discriminate prices, as always used to urge people to use washing machines in low-peak hours. And a study from a University...... 3. But batteries are not like washing machines, since different battries have different capacity and may need different time to recharge. Also, the new tech may allow them to be recharged very quickly. Besides, hybrid cars can use petrolum instead of electricity. 4. Then the machine designed by the University will find its use. It use computer to calculate how much should be needed to recharge. A person only have to tell the computer when it will use the car and how long it will drive, then machine will calculate then when to charge the battery. 5. A kind of such machine has been developed in Japan by Nissan. The inventors also want this device to act as energy reservior to help reserve energy when typhoon or earthquake occurs.
Far better, reckon Alex Rogers and his colleagues at Southampton University, in England, for car owners to be represented in their interactions with the local power supplier by agents that can negotiate a deal on their behalf.
