Hybrid vehicle storage battery and battery management unit encapsulating structure
Technical field
The utility model relates to storage battery and battery management unit encapsulating structure, relates in particular to a kind of hybrid vehicle storage battery and battery management unit encapsulating structure.
Background technology
In automobile industry, orthodox car adopts internal combustion engine that power is provided, yet internal combustion engine need consume fossil fuels such as gasoline, diesel oil when power is provided, and fossil fuel produces vehicle exhausts such as great amount of carbon dioxide, sulfur dioxide, contaminated environment in combustion process.And along with the minimizing day by day of earth fossil fuel, people begin to consider new energy approach, and hybrid vehicle arises at the historic moment like this, and hybrid power is meant by fossil fuel and storage battery provides power jointly.
Compare with orthodox car, hybrid vehicle in use, various external equipments, for example air-conditioning, stereo set are also more and more, therefore the amount of power supply demand to various external equipments also becomes big.Generally be to adopt the low pressure lead acid accumulator that various external equipments powers in orthodox car, and general what adopt is the high storage battery power supply of storage performance at hybrid vehicle, lithium-ions battery for example, this be because of:
Orthodox car needs storage battery that the current start engine is provided in start-up course, along with vehicle becomes big, engine displacement is also big more, therefore the electric current that needs storage battery to provide is also big more, the battery capacity of general minicar is between 32~45Ah, compact car is between 42~60Ah, middle-and-high-ranking big discharge capacity car is generally between 60~90Ah, luxury big discharge capacity vehicle even can use the storage battery of 120Ah left and right sides capacity, therefore orthodox car 12V storage battery battery capacity is generally bigger, and this causes storage battery weight big and to account for volume big; But hybrid vehicle is equipped with high voltage power battery pack and drive motors, in start-up course, utilize the high-tension battery group to provide electric current direct ato unit to drive motors, starting current to storage battery requires to reduce greatly, therefore, the storage battery battery capacity of using in the hybrid vehicle is generally all smaller, simultaneously because the lithium-ions battery energy density is big, so lithium-ions battery is in light weight and to take volume little, this helps the automobile lightness and saves the space;
In addition, lithium-ions battery is compared with the low pressure lead acid accumulator, also has following advantage:
The cycle life of lithium-ions battery generally is 4-5 times of traditional lead acid accumulator cycle life;
Lithium-ion battery charge-discharge efficient is higher, helps energy-conservation;
Lithium-ions battery does not contain heavy metal harmful substance, environmental protection.
Different with orthodox car low pressure lead acid accumulator is, the hybrid vehicle storage battery, for example lithium-ions battery in use need carry out excessive too small, temperature conditions of charging and discharging currents, voltage etc. to storage battery by battery management unit and control with life-saving.In the prior art, for storage battery and battery management unit are fixed on the automobile, general elder generation is encapsulated in the battery case after several secondary battery units are connected, and battery management unit is encapsulated in other the shell, distinguishes self-contained battery case and shell then.Done following 2 deficiencies like this:
1) because storage battery battery module and battery management unit encapsulate respectively, cause wiring between the two elongated, these wiring meetings come in contact with other wirings, are difficult to discern and might be short-circuited;
2) because storage battery battery module and battery management unit encapsulate respectively, cause the battery module layout not compact, integrated not high, it is big to take volume.
In view of this, in fact be necessary to propose a kind of hybrid vehicle storage battery and battery management unit encapsulating structure, avoid that wire harness and other wirings come in contact between storage battery and battery management unit, and be easy to identification, while battery module compact in design, integrated height, it is little to take volume.
