Description
Technical field
The present invention relates to a kind of electric cars.
Background technique
In recent years, the increasingly exhausted and environmental pollution of petroleum resources is got worse, and the utilization rate of electric car is more next
It is higher.But compared with the popularity rate of fuel vehicle and receptance, electric car is still too far behind to catch up.
Does is so influencing the basic reason of electric car popularity rate what?
(1) mileage travelled falls short of after battery disposably charges, because current all battery specific energies are low, caused by cruising ability
Not enough.
(2) charging time of battery is too long, and no matter such as battery can be all greatly lowered with quick charge in which kind of battery at present
Capacity and service life, and even so-called quick charge is also required to nearly half an hour, and is charged in peak times of power consumption
This can also be greatly increased, and influence the service efficiency of vehicle.
For these reasons, it changes power mode operation and gives birth to, for charging, when changing electricity first can save a large amount of
Between, next, which changes electricity and can avoid peak of power consumption, charges, and changing electricity again, to occupy parking stall few.But it changes power mode also and has and is certain
Restriction condition, mostly come from power battery pack cannot be general.
Currently, power battery used in different brands and the electric car of model is different, and each vehicle factor is all root
According to the inner space designed, designed of respective automobile.If an electrical changing station will be changed for the electric car of different brands and model
Electricity, then need to be equipped with the battery of different model, however enter the station change electricity electric car brand and model be it is uncertain, very
It is possible that will appear the inadequate situation of a certain size battery.If an electrical changing station is only the electric car of single brand and model
It carries out changing electricity, then just needing respectively to build a station for the electric car of different brands and model, wastes land resource.
