Abstract
The emergency continuation of the journey device after three-wheeled electric vehicle lithium battery is used up is taken turns the utility model relates to one kind two, shell including having connector, connector is connected with lithium battery/lithium battery group that external electric vehicle is filled, it is characterized in that, connector is connected by the normally opened contact controlled by relay with the capacitor assembly being set in shell, the control terminal of relay is connected with controller, the signal acquisition terminal connection capacitance voltage acquisition unit and lithium battery voltage acquisition unit of controller, capacitance voltage acquisition unit is connected with capacitor assembly, lithium battery voltage acquisition unit is connected by connector with lithium battery/lithium battery group that external electric vehicle is filled.When the controller of the utility model detects that two wheels, three-wheeled electric vehicle matched lithium battery/lithium battery group Voltage Drop are not enough to start two wheels, three-wheeled electric vehicle, controller controls the relay in shell and is attracted, so that two wheels, three-wheeled electric vehicle with emergency starting and can be continued a journey using the heavy-current discharge performance of capacitor, solves the problems, such as several kilometers last.
Description
Technical field
The utility model relates to a kind of for two wheels, the emergency continuation of the journey device of three-wheeled electric vehicle.
Background technique
Use two wheels, three-wheeled electric vehicle as the people of walking-replacing tool often to encounter this embarrassment: being away from home soon or
Destination is several kilometers only last, and how the matched lithium battery group of electric vehicle but depleted of energy cannot all start.Directly electricity
Motor-car is placed on scene and worries, again too laborious shifting destination onto or pushing back house.Especially encountered in scorcher or big cold day
Such case is even more to make the matter worse.
Utility model content
The purpose of this utility model is: after the conventional lithium battery group energy depletion of electric vehicle, providing additionally for electric vehicle
Electric power.
In order to achieve the above object, there is provided one kind two to take turns three-wheeled electric vehicle lithium battery for the technical solution of the utility model
Emergency continuation of the journey device after using up, the shell including having connector, connector and shell outer motored lithium battery/lithium battery group
It is connected, which is characterized in that connector is connected by the normally opened contact controlled by relay with the capacitor assembly being set in shell,
The control terminal of relay is connected with controller, and the signal acquisition terminal of controller connects capacitance voltage acquisition unit and passes through connector
External lithium battery voltage acquisition unit, capacitance voltage acquisition unit is connected with capacitor assembly, lithium battery voltage acquisition unit
It is connected by connector with lithium battery/lithium battery group.
Preferably, the microfarad numerical value of the capacitor assembly is greater than the ampere-hour numerical value of the lithium battery/lithium battery group
10000 times.
When the controller of the utility model detects that two wheels, three-wheeled electric vehicle matched lithium battery/lithium battery group voltage fall
It falls when being not enough to start two wheels, three-wheeled electric vehicle, controller controls the relay in shell and is attracted, and utilizes the high current of capacitor
Discharge performance makes two wheels, three-wheeled electric vehicle with emergency starting and can continue a journey, and solves the problems, such as several kilometers last.
Detailed description of the invention
Fig. 1 is schematic diagram provided by the utility model.
Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
As shown in Figure 1, the emergency continuation of the journey after a kind of two wheels three-wheeled electric vehicle lithium battery provided by the utility model is used up fills
It sets, the shell including having connector, shell is externally provided with lithium battery/lithium battery group that electric vehicle is filled, this lithium battery/lithium battery
Group is connected with connector.Connector is connected by the normally opened contact controlled by relay with the capacitor assembly being set in shell,
The control terminal of relay is connected with controller, and the signal acquisition terminal of controller connects capacitance voltage acquisition unit and passes through connector
External lithium battery voltage acquisition unit, capacitance voltage acquisition unit is connected with capacitor assembly, lithium battery voltage acquisition unit
It is connected by connector with lithium battery/lithium battery group.The microfarad numerical value of capacitor assembly is greater than the lithium battery/lithium battery group
10000 times of ampere-hour numerical value.Such as the corresponding matched capacitor assembly numerical value of 20 ampere-hour lithium battery groups is greater than 20 × 10000
=200000 microfarads i.e. 0.2 farad.
The principles of the present invention are: the quick charge of electricity container component and rapid large-current discharge performance, two take turns,
The matched lithium battery group of three-wheeled electric vehicle has travelled when for a long time exhausting electric energy and restarting the state for needing great start-up current, at this time by
Increase in the internal resistance of lithium battery/lithium battery group, needs to release high current Shi Erfang and do not go out high current to start.This time control
Device processed detects that lithium battery/lithium battery group Voltage Drop is more, and the capacitance voltage of capacitor assembly can support lithium battery/lithium
The normally opened contact of battery pack, relay is attracted, and connects capacitor assembly and connector.Connector passes through outsourcing cable connection to electricity
Battery/lithium battery group of Motor Car Institute dress, plays the high current moment output performance of capacitor, makes to depend merely on two wheel three-wheeled electrics originally
The two wheel three-wheeled electric vehicles that the mating lithium battery group of vehicle cannot start can star, and reach the emergency continuation of the journey of the utility model.
