Benefits of technology

The electrical car driving system uses two types of power sources: one for starting up an engine while another voltage level helps maintain good performance even if there are sudden changes like overheated wires that could affect its ability to start up properly. This allows multiple charged batteries at once to provide more flexibility than just having only one type of source available.

Problems solved by technology

This patents describes how electric car manufactures have been trying to reduce their carbon footprint while maintaining good fuel economy standards through increased emissions control laws. One solution involves adding more lithium ion technology into hybrid electric vehicles - specifically replacing traditional fossil fuels like gasoline and diesel oil with clean sources such as solar cells. Another option would involve developing new types of batterles called zero emission lead acid storage batteries (ZESBs), where they could store electrical charges during operation instead of relying solely upon conventional AC/DC converders.
