The invention relates to the field of electricity, in particular to a power supply system and a power supply method capable of storing redundant electric energy in batteries. The power supply system comprises a connection controller which is connected with a plurality of batteries respectively and is used for controlling the connection / disconnection state between the batteries and a voltage increasing and shunting device and simultaneously for controlling the connection / disconnection between the batteries and a charging device. The voltage increasing and shunting device is connected with the connection controller and comprises a voltage increasing structure and a current diverter. The voltage increasing structure is used for increasing the voltage of the electricity provided by the batteries. An input terminal of the current diverter is connected with the voltage increasing structure; one output terminal of the current diverter is connected with a vehicle; and another output terminal of the current diverter is connected with the charging device. The current diverter is used for dividing the electric energy with increased voltage into at least two parts, namely one part of electric energy which equals to the electric energy needed by the vehicle running at the highest speed, and the rest part of electric energy which is partly or wholly transmitted to the charging device and is stored in batteries connected with the charging device.
Description
technical field [0001] The invention relates to the field of electricity, in particular to a power supply system and a power supply method. Background technique [0002] Cars have been used as a means of transportation for more and more people. At present, the annual car sales are growing at a relatively high rate. Since most cars mainly rely on burning gasoline, diesel and other energy sources as power, the tail gas emitted by cars has aggravated air pollution. Automobile exhaust mainly includes: carbon monoxide, hydrocarbons, nitrogen oxides, sulfur dioxide, soot particles, odor, etc. According to statistics, every thousand vehicles emit about 3000 kilograms of carbon monoxide, about 200-400 kilograms of hydrocarbons, and about 50-150 kilograms of nitrogen oxides every day. For example, photochemical smog, the hydrocarbons and nitrogen oxides in automobile exhaust react chemically under the action of sunlight to generate ozone, which combines with other components in the...
