Description
Technical field
The utility model is related to electric vehicle battery system, more particularly to a kind of battery system of electric motor car high-voltage safety
System.
Background technology
The characteristics of new-energy automobile is because of zero-emission, no pollution, is developed rapidly in recent years.The work(of vehicle motor
Rate is increasing, it is desirable to which course continuation mileage is more and more remote, and these features require battery capacity more and more higher, but it is limited to electricity
Pond group battery core monomer capacity.It is that more battery modules in parallel form battery pack to increase one of measure of capacity at present, accordingly very
Many battery producers all devise the battery pack standard container of oneself uniqueness, and there are different requirements in different car enterprises, causes to lead to
With, if the battery modules arrangement in the change battery quasi- case of mark group can waste the plenty of time, the payment of serious delayed product.Separately
Outward, if multiple battery packs are connected into a standard battery module, then multiple standard battery modules are incorporated into high-voltaghe compartment
Parallel connection is carried out, then can reach increase battery capacity, reduce the purpose of product development cycle.But multiple standard battery modules are straight
Connect and be incorporated into high-voltaghe compartment, many hidden danger can be triggered, such as electric spark occurs when plugging high-pressure insert, in addition, there is part
Standard battery module is not controlled by service switch, and electric current is excessive in single service switch causes fuse and service switch chi
Very little mismatch etc..
Utility model content
The utility model provides a high tension battery bag for safety, it is adaptable to which multiple battery systems are introduced into high-voltaghe compartment
Safe design, mentality of designing is simple, and low cost, general strong.
The utility model solves the technical scheme that its technical problem used:
A kind of battery system of electric motor car high-voltage safety, including battery management system and the mark that is in series by battery pack
Quasi- battery module, the standard battery module is connected by high-tension terminal with service switch, is connected by first between service switch
Connected by the second connecting copper bar and battery management system again after connecing copper bar parallel connection;Is connected with the middle of second connecting copper bar
One fuse.
Further scheme, the high pressure connecting hole on the first high pressure connection terminal and high-tension terminal on the service switch connects
Connect, the through hole in the second high pressure connection terminal and the first connecting copper bar is connected;The standard battery module is by plug and height
Pressure socket is connected.
Further scheme, the electric current flowed through on the service switch is the standard battery module that the service switch is controlled
Charging and discharging currents.
Further scheme, the service switch includes switch, and the switch is in series with second fuse.
Battery management system in the utility model(BMS)It is existing, is the system carried in electrokinetic cell, it is mainly
For intelligent management and each battery unit is safeguarded, prevent battery from overcharge and overdischarge occur, extend the use longevity of battery
Life, monitors the state of battery.
The utility model is connected a service switch using each standard battery module, and by the output of standard battery module
End is connected by high-tension terminal with the input of service switch, then each service switch controls often to cover standard battery module respectively,
Make multiple standard battery module independent operatings, it is possible to avoid partly percentage of batteries system being avoided not controlled by service switch
Do not controlled by service switch;And the electric current flowed through on each service switch is the charging and discharging currents of the standard battery module, its
Size of current is controllable, is easy to the fuse chosen and service switch size matches.If multiple standard battery modules are direct
The front end of service switch is incorporated into, can be because pressure difference be electric spark situation occur in plug high-pressure insert, together between these systems
When can be because electric current be excessive cause fuse and service switch size mismatch problem in single service switch;If being by part
System is incorporated into the rear end of same service switch, and these battery systems can be caused not controlled by service switch, it is impossible in time by high pressure
It is electrically cut off, field maintenance potential safety hazard is than larger.
So battery system of the present utility model can avoid electric spark phenomenon occur when high-pressure insert is plugged, protect
Shield personal safety;Can also avoid causing fuse and service switch size mismatch to be asked because electric current is excessive in single service switch
Topic.
In addition, second fuse is equipped with each service switch, can be to the monomer in each standard battery module
Battery is protected.
Be together in parallel for the output end of service switch using connecting copper bar by the utility model, and connects first in its output end
Fuse is used for protecting total battery system, can also effectively protect the second fuse in multiple service switch, effective drop
Low-risk, it is cost-effective.
Service switch in the utility model is to be pure electronic and hybrid vehicle high-voltage electric power system in maintenance
The repair and maintaining that safety is provided and the function that safeguard protection is played to power system.It is the product that can be directly bought from market.
