Description
Technical field
The present invention relates to new-energy automobile fields.
Background technique
Currently, the power supply mode of traditional new-energy automobile low voltage control unit is to pass through new-energy automobile high voltage supply list
Member takes high-voltage electricity, is converted into the electricity used for low voltage control unit by DCDC (high voltage direct current turns low-voltage direct) control unit
After pressure, charge for vehicular electricity storage vapour.Electric power storage tank discharge is the power supply of each quasi-controller.
Above traditional electric car vulnerabilities scan device power supply uses low-voltage power supply, power supply mode must pass through battery with
High-tension battery group high pressure is converted to low pressure (12V or 24V) to charge the battery using DCDC controller by DCDC controller, is led to
Crossing electric power storage tank discharge is that all controllers power supply or more electric car power supply mode has disadvantage are as follows:
The increased costs of battery integral vehicle cost
New-energy automobile course continuation mileage and complete vehicle quality have much relations, and complete vehicle quality is heavier, and continuation of the journey decline is faster.With storage
Battery is in quality generally 30KG or so (specific related to capacity).Occupy very big specific gravity on complete vehicle quality.
Battery is sufficiently bulky, occupies vehicle inner space, reduces vehicle available space.
Summary of the invention
The technical problem to be solved by the present invention is to realize that high tension battery can be used in one kind to replace low tension battery, lead to
Cross the system that DCDC carries out voltage conversion and energy distribution.
To achieve the goals above, the technical solution adopted by the present invention are as follows: a kind of electric car light current power supply system, it is electronic
Automobile is equipped with the high-tension battery group being made of battery cell, and the high-tension battery group is equipped with high pressure and is always just always bearing with high pressure, described
High pressure is always just always born with high pressure and is separately connected the input terminal of DCDC controller, the output end of the DCDC controller be low pressure always just
It is always born with low pressure, the low pressure always bears the power input that vehicle-mounted electric component is always just being separately connected with low pressure.
Light current general power when the maximum power of the DCDC controller is less than or equal to vehicle launch, the electric component
Low pressure between DCDC controller, which is always just always born with low pressure, is connected with capacitor.
The capacitor that low pressure between the electric component and DCDC controller is always just always being born with low pressure be equipped with it is multiple, it is more
A capacitor constitutes shunt capacitance group.
Low pressure between the electric component and DCDC controller always just on be in series with fuse.
The electric car includes pure electric automobile, mixed electrical automobile, alkene material automobile.
The advantage of the invention is that reducing vehicle cost, secondary battery unit, periphery auxiliary harness cost are saved, vehicle takes storage
Battery, complete vehicle quality decline, vehicle continuation of the journey increases, but also making vehicle that can become larger using space.
Detailed description of the invention
Below to width attached drawing every in description of the invention expression content and figure in label be briefly described:
Fig. 1 is electric car light current power supply system schematic diagram；
Label in above-mentioned figure is equal are as follows: 1, high-tension battery group；2, battery cell；3, DCDC controller；4, shunt capacitance group；
5, capacitor；6, low pressure is always born；7, fuse；8, low pressure is being always just；9, electric component；10, high pressure is always born；11, high pressure is being always just.
Specific embodiment
Below against attached drawing, by the description of the embodiment, for example related each component of a specific embodiment of the invention
Shape, construction, the mutual alignment between each section and connection relationship, the effect of each section and working principle, manufacturing process and
Operate with method etc., is described in further detail, to help those skilled in the art to inventive concept of the invention, technology
Scheme has more complete, accurate and deep understanding.
Electric car is that conventional fuel oil automobile upgrade, and has no and optimizes in terms of weak electricity system, only simple
It is single to substitute the small generator of traditional vehicle using DCDC controller 3 and carry out but in view of current electric car has on-board high-voltage
System is stored with the electricity that driving vehicle is exercised, thus high-tension battery group 1 (power battery) can be used and replace low pressure electric power storage
Pond carries out voltage conversion by DCDC controller 3 and energy distributes.
During electric car starts, in the case where some electric vehicle controllers are relatively fewer, can directly it lead to
Light current can be provided to controller after fuse 7 by crossing DCDC controller 3.Electric vehicle controller is more together, starts punching
In the case where hitting greatly, 5 parallel connection of capacitor can be used to adjust vehicle launch impact, solve the electricity of vehicle-mounted low pressure power unit
Source powerup issue makes vehicle cancel low tension battery, saves integral vehicle cost and reduces kerb weight.
As shown in Figure 1, electric car is equipped with the high-tension battery group 1 being made of battery cell 2, electric car includes electronic vapour
Vehicle, all kinds of mixed electrical automobiles and alkene material automobile etc..High-tension battery group 1 provides high drive energy for new-energy automobile.High-tension battery
1 output electricity of group provides electric current by total minus 10 composition of high pressure total positive 11 and high pressure for exterior vehicle driving motor.
Draw in total minus 10 circuit of high pressure total positive 11 and high pressure that high-tension battery group 1 is exported and take high-tension current, passes through high pressure
Turn low-voltage DC/DC controller 3 and be converted to light current voltage used in controller, after shunt capacitance group 4 and serial fuse 7, leads to
Crossing low pressure total minus 6 and low pressure total positive 8 is all weak electrical appliance components 9 of automobile to provide electricity.
If shunt capacitance group 4 is formed in parallel by dry condenser 5, the excellent dynamic and starting-impact of electrical equipment is predominantly solved.Tool
In practical applications, if weak electrical appliance component 9 is less, and light current general power when vehicle launch is less than DCDC controller 3 to body
When maximum power, capacitance group can be cancelled and directly used.If it is maximum that light current general power when vehicle launch is greater than DCDC controller 3
When power, the capacitor of adjustable shunt capacitance group 4 is adapted to starting power.Concatenated fuse predominantly solves to set in electricity consumption
When standby short circuit or excessive electricity consumption instantaneous power, fuse protection is carried out, the damage of DCDC controller 3 is prevented.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out is used, or without changing
It is within the scope of the present invention into the conception and technical scheme of the invention are directly applied to other occasions.
