A range extender all-in-one machine with infrared remote control digital frequency conversion function

Abstract

The invention provides an all-in-one range extender with infrared remote control and digital frequency conversion functions. The all-in-one range extender comprises a controller, a rectifier bridge and a power generator which are assembled together, wherein the controller comprises an infrared transmit-receive unit and a digital frequency conversion control unit; and an infrared remote control unit is independently configured. The all-in-one range extender provided by the invention is equipped with the infrared remote control unit, so that one and the same controller can be used for adapting to different motor types, and the problems about diversification and non-unified specifications of controllers can be solved for users; through the digital frequency conversion unit, the problem about storage battery damage caused by uncontrollable power generating pressure of the power generator can be solved, so that the service life of a storage battery can be greatly prolonged when strong power is provided, that is, the all-in-one range extender has the advantage that the storage battery is truly not damaged; through the mechanical-electrical integrated design, the problems that the heat productivity of the rectifier bridge is high and heat dissipation is difficult can be solved; and meanwhile, the wiring mode is simplified, thereby providing convenience and stability for the user.

Description

technical field [0001] The invention belongs to the field of electric vehicles, in particular to a range extender integrated machine with an infrared remote control digital frequency conversion function. Background technique [0002] With the development of energy saving and emission reduction technology, the development of pure electric tricycle and electric motorcycle technology has become inevitable. Existing pure electric tricycles and electric motorcycles rely entirely on storage batteries (storage batteries) to provide power, and the capacity of storage batteries (storage batteries) is certain, therefore, the mileage that the storage batteries can charge once for electric vehicles is limited. When the electric vehicle runs out of power in the battery, the battery cannot provide enough power for the electric vehicle, and the electric vehicle cannot move forward. However, the charging method using commercial power is extremely slow and requires a specific charging place...

AI Technical Summary

Problems solved by technology

[0006] 1. Because the power and voltage of the driving motor equipped with the electric vehicle are inconsistent, it is necessary to be equipped with range extenders of different power and voltage, and each type of range extender needs a matching starter, so the required starter There are at least 10 kinds of combinations and collocations, and there are many types, which is very inconvenient for both manufacturers and users

[0007] 2. The specifications of batteries on the market are also different, and the requirements for charging current are also different. However, the range extender controllers currently on the market adjust the speed and output of the generator according to the signal of the turning handle. The power generation of the generator is completely determined by the It is determined by the turning handle, not by the actual demand. As a result, under heavy load, the power generation is insufficient and the driving capacity is not enough to charge the battery. When the load is small, the power generation is excessive and the charging current of the battery is too large, which greatly damages the life of the battery.

[0008] 3. The starter, rectifier bridge, and generator are equipped separately, the circuit is complicated, the assembly is difficult, and the user usability and maintainability are poor.

At the same time, the heat dissipation of the rectifier bridge needs to add an additional heat dissipation aluminum part, and it can only dissipate heat by itself. While the cost increases, the heat dissipation effect is not good.
