As for the problem of an electric car related to electric energy supply, the invention provides a charging system of the electric car. The charging system of the electric car is characterized by comprising a parallel-operated power supply unit, an electric power multi-element transmission module, a vehicle storage battery multi-element charger and a charging multi-element leading-out terminal, wherein the parallel-operated power supply unit is protected by a high-voltage relay device and a low-voltage relay device and can provide a three-phase electrical signal and a monomial electrical signal; the electric power multi-element transmission module has a breaker function and can conduct the opening or closing operation on a power-up state through manual operation or electric drive; when abnormal conditions such as overload, short circuit, undervoltage and undercurrent occur, the current can be broken down automatically; the vehicle storage battery multi-element charger can convert the received electric signals in an alternating mode to electric signals in a direct current mode through the electric power multi-element transmission module; by means of the charging multi-element leading-out terminal corresponding to the vehicle storage battery multi-element charger, quick charging can be conducted on multiple electric cars at one time.
Description
Technical field: [0001] The field of the invention is a charging system, especially a charging system for an electric vehicle. Background technique: [0002] With the rapid development of human society, global oil resources are becoming increasingly depleted and the natural environment on which human beings depend is deteriorating. As a convenient and fast means of transportation in modern civilized society, automobiles have brought great promotion and convenience to the development of human society and people's lives, but at the same time, they are also eating up fuel consumption, which accounts for 75% of the total oil energy consumption. And it also brings huge pollution to people's living environment. Electric vehicles are based on electricity as the power source, and electric vehicles replace fuel engines with electric motors. Electric vehicles can not only achieve zero emissions, low noise, and no pollution, but also can save a large amount of increasingly depleted pe...
