Description
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;
