Description
Technical field
The utility model belongs to battery boosting technology field, and in particular to a kind of novel quick-charging circuit device.
Technical background
In recent years, it has increasingly been attracted attention by people in the development of energy automobile, in increasingly developed today, new-energy automobile
Cruising ability improving year by year, this requires the promotions of the batteries to store energy ability of automobile.Generally acknowledged at present is fast filled with Tesla
Super charge, it is probably 2 ~ 3 hours grades that about half an hour, which can fill 80% electricity and other several automobiles,.But
So high charging current, brought harm is significant.Such as on January 6th, 2106, one in Norway's Yale this tower was super
Charging station, tesla Model S charging are on fire；On March 16th, 2017, the super charging station of Golden Bridge in Shanghai, tesla Model
S charging is on fire.Leading to reason on fire is the charge power of superelevation.It is reported that super charging station is that tesla takes pride in the most
One of technology, user can be full of half mileage with 20 minutes, be completely filled within 75 minutes or so.But bring is therewith
The instantaneous power of 120kW or so, so high charge power, there is great security risks.
Utility model content
The utility model provides a kind of novel quick charge device, and charge power is relatively low, meets security performance
It is required that.
To achieve the above object, the utility model uses following technical scheme:
A kind of novel quick-charging circuit device has the charging input end for passing sequentially through electrical connection, electric current caching dress
It sets, voltage constant device, switch K, current storage means,
The connection of the input endpoint of the charging input end and power supply；
The electric current buffer storage includes the super capacitor being electrically connected with charging input end；
The voltage constant device includes the chip being electrically connected with super capacitor；
One end of the switch K is connected electrically in the anode of battery in the current storage means, and the other end is electrically connected battery
Cathode.
Further, the current-limiting apparatus being electrically connected is provided between the super capacitor and chip.
Further, the current-limiting apparatus is current limiter.
The utility model structure is simple, in traveling energy supplement during the journey, the charging time to be shorter, when theoretical calculation
Between only tens seconds to a few minutes or even shorter.In the meantime, automobile can not influence super capacitor to electric power storage with normally travel
Pond charging.Due to the intrinsic characteristic of capacitor, can not long-time storage electricity, only capacitor is temporarily stored as charge set here
It is standby.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Wherein, in figure, 1, super capacitor, 2, current limiter, 3, chip, 4, battery.
Specific embodiment
As shown in Figure 1, a kind of novel quick-charging circuit device, it is characterised in that: it, which has, passes sequentially through electrical connection
Charging input end, electric current buffer storage, voltage constant device, switch K, current storage means, the charging input end and power supply
Input endpoint connection；The electric current buffer storage includes the super capacitor 1 being electrically connected with charging input end；Though super capacitor 1
Right charging rate is fast, but when electric discharge, voltage can be reduced with the time, this just necessarily requires constant by a voltage
Device exports constant voltage, and to meet the voltage requirement charged to battery 4, therefore the chip of TI can be used in we
BQ25504 realizes this function；The voltage constant device includes the chip 3 being electrically connected with super capacitor 1；The switch K's
One end is connected electrically in the anode of battery in the current storage means, and the other end is electrically connected the cathode of battery.The super capacitor 1
The current-limiting apparatus being electrically connected is provided between chip 3, the current-limiting apparatus is current limiter 2, is avoided because of electric current when capacitor discharges
It is excessive, circuit is damaged.External power charges to capacitor charging, capacitor to battery 4, battery 4 is Automobile drive power supply,
Three circuit control systems separate, and do not interfere with each other.Chip 3 selects the chip BQ25504 of the chip BQ25504:TI of TI inputting
When voltage is between 80mV to 3V, the constant direct current output of 3V can be generated.
The workflow of the utility model is as follows:
Apply external power (direct current) charging, switch K is disconnected, and is at this time super capacitor charging, the used time is very short, and (tens seconds arrive
A few minutes)；After super capacitor charges, external power is disconnected, close a switch K, and super capacitor is to charge the battery at this time.
