The shortcomings of of long duration is also the factor for restricting electric car development.To solve the above problems, mainly have two schemes on Vehicles Collected from Market,
First, parallel hybrid power is used as the energy (internal combustion engine and the equal drivable wheel of battery), second, by secondary power to vehicle-mounted
The series system that battery is recharged, the secondary power are the distance increasing unit being mentioned below.
Distance increasing unit has the advantages that low in energy consumption, endurance is strong, mesh as a kind of emerging electric motor car energy solution
Before be commercially available and widely use.But electric car species is various on current market, storage battery model is inconsistent, and power demand is not
Unanimously, installation requirement is inconsistent, cause on the market distance increasing unit controller it is multifarious, specification is mixed and disorderly, poor universality.Existing market
On driving motor of electric vehicle power, therefore support the use that distance increasing unit power is various, and main flow has 1KW, 2KW, 3KW etc., often
Voltage corresponding to a kind of controller again, main flow 48V, 60V, 72V.Therefore, the increasing journey for each voltage with power
For device, different controllers will be corresponded to set respectively.
In addition, existing distance increasing unit controller function is not perfect enough, electric vehicle accumulator excessively it is time-consuming just charge and full of when increase
Situations such as journey device continues to work can cause storage battery life consumption；Generator fuel oil surplus is not clear also to largely effect on electric car
Endurance.
The content of the invention
The invention provides a kind of distance increasing unit controller being remotely controlled using Wi-Fi, solves distance increasing unit of the prior art
Controller poor universality, control function, which is not enough improved, causes storage battery life consumption, the problem of influenceing electric car endurance.
The technical scheme is that a kind of distance increasing unit controller being remotely controlled using Wi-Fi, including controller and correspondingly match somebody with somebody
The Wi-Fi equipment put, controller are internally provided with main control MCU, main control MCU respectively with sensor, voltage x current collecting unit,
Wi-Fi Transmit-Receive Units, electric-motor drive unit connect with digital converter unit signal；Wi-Fi Transmit-Receive Units by Wi-Fi network with
Wi-Fi equipment wireless connection；Electric-motor drive unit and digital converter unit are connected with distance increasing unit generator control simultaneously.
The distance increasing unit controller being remotely controlled using Wi-Fi of the present invention, its feature are also included：
Described distance increasing unit generator is connected with rectifier bridge, and the rectifier bridge other end takes back controller, and control is taken back in rectifier bridge
Storage battery is parallel with the loop of device processed.
Described Wi-Fi equipment uses mobile phone or remote control.
Present invention has the advantages that on the composition basis of existing distance increasing unit, a Wi- is added in controller part
Fi Transmit-Receive Units, controlled by outside Wi-Fi equipment (such as mobile phone) so that producer and user can use same controller
Different motor types is adapted to respectively, and the species for solving controller is various with the skimble-scamble problem of specification.The controller simultaneously
Storage battery use can also be fed back by Wi-Fi network to outside Wi-Fi equipment Real-time Feedback fuel oil surplus and course continuation mileage
Situation, so as to avoid the occurrence of, storage battery crosses consumption traveling or storage battery is had been filled with still in situation about being charged using distance increasing unit, there is provided increases journey
Device generator opens and closes the function of prompting or automatic switch, extends battery life, strengthens battery truck endurance.
