Description
Technical field
The invention belongs to the automotive electronics applied technical field, be specifically related to the cooling system design of plug-in hybrid-power automobile with battery pack.
Background technology
Electrokinetic cell is the hybrid vehicle kernel component, the superior direct quality that influences vehicle performance of its performance.Lithium ion battery is the new battery that the rises nineties in last century, has that volume is little, specific energy and specific power height, voltage height, the life-span is long and advantage such as environment friendly and pollution-free.But lithium ion battery is comparatively responsive to temperature, it shows different charging and discharging curve characteristic (capacity, internal resistance, power etc.) under different temperature, the difference of temperature is the main cause that causes the battery consistency difference in the same power brick, and the power brick bulk life time descends significantly after causing battery in groups.
For the large-sized power battery that car load uses, because the battery cell layout is more, and is subjected to the limitation of arrangement space to influence flow field uniformity, just there are the uneven temperature potential problems in itself.If only depend on the Homogeneouslly-radiating that battery prescription levelling and power brick structural design can not fine solution power brick, must the outfit cooling system.
Efficiently radiates heat when battery pack temperature is too high and ventilation can guarantee the even distribution in temperature field; And extract out fast outside the Battery case by available ventilation when pernicious gas produces, reduce infringement the driver.By monitoring equipment, heat transfer medium, blower fan, battery case, refrigerant system design to reach the purpose of heat management.Selecting the suitable type of cooling is the prerequisite of each battery module temperature of equalization.Can be divided into according to coolant: water-cooled, air-cooled; Wherein water-cooled adopts water or ethanol as coolant, possess the position insensitive, the advantage that the adaptive temperature scope is wide, but have complex structure, cost height, safeguard shortcoming such as complexity, so use less at present; Though air cooling way has shortcomings such as the low and adaptive temperature narrow range of efficient, and the car load air-conditioning system in conjunction with after have and improve significantly, add and possess simplicity of design, cost is low, be easy to realize etc. advantage is the main flow of present application.The air cooling system of battery is divided into series connection and two kinds of parallel connections, though series connection has simple and the low characteristics of cost, has the big shortcoming of the battery pack temperature difference, and cooling system in parallel is subjected to car load arrangement space limitation, and cooling effectiveness is lower.
The serial mixed power battery pack is as car load power major impetus source, and its service conditions is quite abominable, the present invention is directed to serial type hybrid automobile rectangular lithium ion battery group and adopts air cooling, has effectively overcome the above-mentioned shortcoming of cooling air mode.
Summary of the invention
Order of the present invention ground is to satisfy plug-in hybrid-power automobile exploitation needs, a kind of Hybrid Vehicle lithium-ion battery systems is disclosed, radiator structure at the rectangular lithium ion battery system, promote the uniformity and the cooling effectiveness in battery pack temperature field in use, improve the reliability and the consistency of battery performance, thereby improve the performance and the safety in operation of car load, to promote the hybrid vehicle exploitation.
A kind of Hybrid Vehicle lithium-ion battery systems, it includes Battery case, is installed in the group of battery modules in the Battery case, is installed in the battery management system and the high tension apparatus part of close car load forward engine room one end in the Battery case; Battery case is by being bolted under the car load chassis;
It is characterized in that: described Battery case designs Battery case air outlet at the Battery case other end near boot one end near car load forward engine room one end design Battery case air inlet; Described group of battery modules has some groups, and they become two row to be symmetrically arranged along the turnover wind direction of Battery case, and the group of battery modules in each row is arranged in parallel; About leave air intake wedge shape conduit between the two row group of battery modules, air intake wedge shape conduit is big at the internal diameter near the air inlet place, along with the prolongation in air intake path, internal diameter dwindles gradually, improves cooling effectiveness.About leave the air-out conduit between the outside of two row group of battery modules and the Battery case, the air-out conduit communicates with the Battery case air outlet; Be provided with guide fluid grating in described each Battery pack module group by air intake wedge shape conduit terminal position simultaneously, the front end of guide fluid grating is connected with the end of group of battery modules, and the end of guide fluid grating is towards the air intake direction of air intake wedge shape conduit.After wind is come in from air inlet, if there is not guide fluid grating, air can directly flow to the Battery case rear portion after air inlet is come in, the both sides battery is not played cooling effect, needing to increase windage so makes air evenly spread to the battery pack both sides, be pooled to the air outlet place by the air-out conduit with battery surface at last through heat-exchanged air, extracted out outside the Battery case, the battery assembly is played the effect of cooling by blower fan.
The least significant end that relies on air-out direction in described group of battery modules is provided with deep bead, and the two ends of deep bead extend to the air-out conduit of Battery case both sides always, guides the wind of air intake wedge shape conduit into the air-out conduit.
The present invention compares with existing correlation technique, advantage is that the air channel is designed in the layout gap that makes full use of between the battery modules, overcome the big problem of serial radiating mode and radiator structure in parallel space that existing power brick radiator structure exists, solved the gas long flow path, cooling effect is not obvious, into and out of the bigger contradiction of the air port temperature difference, and the design of this radiator structure has not only guaranteed the temperature homogeneity of battery pack internal cell monomer, and it is simple in structure, easy and simple to handle, manufacturing process is simple, and cost is lower.
