Problems solved by technology
However, there are still some deficiencies in the utilization of electric energy, especially in the demand for electric energy in mobile electric devices. In the case of large demand, the continuous insufficient supply of mobile electric energy restricts the development of many industries. , the electric vehicle industry is a typical representative
[0003] Electric vehicles cannot meet the needs of long-distance operation due to their short mileage
A traditional power management system can only be responsible for and manage one battery box. Even if the user can choose to place multiple heavy battery boxes on the car to deal with the insufficient power supply of one battery box, it is inevitable that the In the process of driving, the power supply of a battery box suddenly runs out and the battery box needs to be replaced manually. This behavior will cause a lot of safety hazards to both people and ourselves on roads or expressways with many vehicles.
Moreover, the charging process of the electric vehicle battery box is time-consuming, even if there is a charging station on the road, it will be excluded from the consideration of car buyers
When the power source is insufficient, it is usually realized by measuring the voltage drop, and at this time the actual remaining power is very small, which often brings a lot of inconvenience to the user, especially when the power supply condition is not allowed
In addition, as the number of times the battery box is used increases, the power storage capacity of the battery box gradually weakens, further reducing the battery life of the electric vehicle

The invention discloses a power supply system, and particularly discloses a power supply system applicable to an electric automobile. The power supply system comprises a primary power supply device and a secondary power supply device, wherein the primary power supply device is insufficient to further provide an electric energy source; and the power supply system is independently and spontaneously switched into secondary power supply device power supply from primary power supply device power supply, so that the inconvenience when a standby battery is manually changed is avoided; and meanwhile, the charge speed of the power supply system is increased.
Description
technical field [0001] The invention relates to a power supply system, in particular to a power supply system and method suitable for electric vehicles. Background technique [0002] Today, when the construction of an environment-friendly society is advocated, with the decrease of petroleum resources and the serious pollution of the atmospheric environment, the use of electric energy is gradually favored by people because of its economical and clean advantages. However, there are still some deficiencies in the utilization of electric energy, especially in the demand for electric energy in mobile electric devices. In the case of large demand, the continuous insufficient supply of mobile electric energy restricts the development of many industries. , The electric vehicle industry is a typical representative. [0003] Electric vehicles cannot meet the needs of long-distance operation because of their short cruising range. A traditional power management system can only be resp...
