Description
Art
The power battery box that electric car uses is the utility model is related to, belongs to electric automobiles.
Background technology
At present, the power battery box that electric car uses, all it is only to focus on radiating, it is impossible to perceive the work of battery well
Temperature and control detonation, hidden danger is left in electrokinetic cell in.
The content of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of power battery box, can be very good monitoring electricity
Chi Xin operating temperature state, avoids deflagration accident.
Technical scheme is used by the utility model solves its technical problem：On battery top, safety relief is set
Valve, when battery internal pressure reaches certain value, safety relief valve is opened, and discharges pressure；Battery internal pressure is discharged into
During certain value, safety relief valve is closed.Battery, battery connect post, connect post conductor tab, temperature control sensor, safety relief
Valve is arranged in Battery case.Groove is set on Battery case, and groove floor seals with battery, relative with safety relief valve
Locate perforate.Connect in battery and temperature control sensor, collecting temperature information transfer to control panel, control panel are set on post connection conductor piece
According to battery operating temperature situation corresponding to single or two temperature control sensors, by comparing, temperature anomaly can be accurately identified
Battery, and show, when temperature reaches certain value, control panel shut-off battery power supply.
When power battery box works, connect because temperature control sensor is arranged on battery on post connection conductor piece, can not only be fast
Speed perceives the contact situation of connection conductor piece, moreover it is possible to quick sensing battery internal operating temperature situation.When a middle battery
When core goes wrong, internal temperature can be raised quickly, the two temperature controls sensing on connection conductor piece being connected with this battery
Device can all collect temperature rise signal and be transferred to control panel, and control panel identifies the battery of temperature anomaly by comparing, and
Show.When first battery or last battery go wrong, or a battery connection conductor piece occurs
During problem, battery internal temperature can be raised quickly, the temperature control sensor on connection conductor piece that only this battery is connected,
Collect temperature rise information transfer and identify the battery of temperature anomaly, and show by comparing to control panel, control panel
Come.When battery temperature reaches certain value, control panel shut-off battery power supply.
Fuel gas can be produced when being worked due to battery, is squeezed when collision internal short-circuit, can cause certainly
Combustion, temperature, pressure is drastically raised, and when pressure reaches certain value, safety relief valve is opened.Again due to being set on Battery case
Groove, groove floor are sealed with battery, and relative with safety relief valve to locate perforate, HTHP battery liquid is released to outside Battery case
Put, so as to protect other batteries in Battery case.When battery internal pressure is discharged into certain value, safety relief valve closes
Close, protect the battery to go wrong to work on.
The beneficial effects of the utility model are：It is quick on the draw accurate, it is simple in construction, can not only each battery of accurate response
Operating temperature situation, moreover it is possible in hypertonia to case release in vitro pressure, protect other batteries, avoid the occurrence of chain quick-fried
Combustion.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the positive structure diagram of power battery box.
Fig. 2 is the side structure schematic view of power battery box.
1. casing in figure, 2. batteries, 3. batteries connect post, 4. connection conductor pieces, 5. temperature control sensors, 6. safety reliefs
Valve, 7. groove floors, 8. control panels.
Embodiment
In Fig. 1, the top of battery 2 sets safety relief valve 6, and battery 2, battery connect post 3, connect post conductor tab
4th, temperature control sensor 5, safety relief valve 6 are arranged in Battery case 1.
When power battery box works, connect because temperature control sensor 5 is arranged on battery on the connection conductor piece of post 3, can be most fast
Speed perceives the internal operating temperature situation of battery 2.When a middle battery 2 goes wrong, internal temperature can be raised quickly,
Two temperature control sensors 5 on connection conductor piece 4 being connected with this battery 2 can all collect temperature rise signal and be transferred to
Control panel 8, control panel 8 identify the battery 2 of temperature anomaly, and show by comparing.When first battery 2 or
When last battery 2 goes wrong, the internal temperature of battery 2 can be raised quickly, the only connected connection of this battery 2
Temperature control sensor 5 on conductor piece 4, temperature can be collected and raise information transfer to control panel 8, control panel 8 is by comparing, identification
Go out the battery 2 of temperature anomaly, and show.When the temperature of battery 2 reaches certain value, control panel 8 turns off battery electricity
Source.
Due to fuel gas can be produced when battery 2 works, it is squeezed when collision internal short-circuit, can causes certainly
Combustion, temperature, pressure are drastically raised, and when pressure reaches certain value, safety relief valve 5 is opened.Again due to being set on Battery case 1
Put groove, groove floor 7 seals with battery, relative place's perforate with safety relief valve 6, and HTHP battery liquid is to Battery case
Discharged outside 1, so as to protect other batteries 2 in Battery case.When the internal pressure of battery 2 is discharged into certain value, safety
Relief valve 6 is closed, and protects the battery 2 to go wrong to work on.
