Problems solved by technology

[0002] In the existing technology, the use of electric vehicles is very limited due to many factors such as long charging time, poor battery life, and high price.
Therefore, if it is impossible to break through the bottleneck in the electric energy storage technology of electric vehicles, it will be difficult to make new energy vehicles widely used in a real sense

Embodiment Construction

[0048] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0049] Please refer to figure 1 , is a schematic structural view of the first embodiment of the electric vehicle provided by the present invention. The electric vehicle includes: a motor controller 1 , a power battery pack 2 , a range-extending battery pack 3 and a motor 4 .

[0050] Wherein, the motor controller 1 may be a bidirectional inverter motor controller. The so-called bidirectional inverter means that the motor controller 1 can realize the mutual interaction between DC (Direct Current, direct current) and AC (Alternating Current, alternating current). convert...

Abstract

The embodiment of the invention provides an electric car and a bi-directional inversion type motor controller. The bi-directional inversion type motor controller comprises bi-directional DC / DC modules I and II and a bi-directional DC / AC module which are connected through busbars. The bi-directional DC / DC module I comprises a battery pack port I connected with a power battery pack. The bi-directional DC / DC module II comprises a battery pack port II connected with a stroke-increasing battery pack. The bi-directional DC / AC module comprises three-phase line connecting ports I and II, wherein the three-phase line connecting port I is connected with a motor, and the three-phase line connecting port II is used for being connected with a power grid or a load. The bi-directional inversion type motor controller can obviously improve the battery cruising power of the electric car.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle and a bidirectional inverter motor controller. Background technique [0002] In the prior art, the use of electric vehicles is very limited due to many factors such as long charging time, poor battery life, and high price. Therefore, if it is impossible to break through the bottleneck in the electric energy storage technology of electric vehicles, it will be difficult to make new energy vehicles widely used in a true sense. Therefore, how to increase the battery life of electric vehicles is a technical problem that those skilled in the art have been eager to solve. Contents of the invention [0003] In view of this, an embodiment of the present invention provides an electric vehicle and a bidirectional inverter motor controller, which can significantly improve the battery life of the electric vehicle. [0004] In order to solve this technical pro...
