Abstract
The utility model discloses a phase change battery pack system. The current sealed battery pack structure is utilized, the phase change battery pack system has an excellent evacuation effect, a problem that the leakproofness of the battery pack is reduced after the battery pack is used for a long time is solved, and the phase change battery pack system timely is used for performing evacuation operation on battery packs of which the vacuum degree is insufficient; the phase change battery pack system is easy and convenient to operate, excellent in effect and high in reliability.
Description
Technical field
The utility model relates to a kind of battery pack system, especially a kind of phase transformation battery pack system.
Background technology
Due to day by day increasing the weight of of global energy crisis and environmental pollution, the development of auto industry also must be taked new solution, and electric automobile just enters into people's sight line gradually.Have benefited from the advantages such as the high voltage, high-energy-density of power lithium-ion battery, good cycle performance, cleanliness without any pollution, be considered to the most promising vehicle power mains.
Power lithium-ion battery must be worked in certain temperature range, and its performance just can be in optimum state.In temperature range, work outward, not only affect cell discharge performance, shorten battery life, and under the condition of high temperature, work and also can reduce the coefficient of safety of battery, further bring that battery discharges gas, smolders, the consequence of leakage, even may cause that battery burns.Therefore, the temperature of power lithium-ion battery is controlled just becomes a major issue.
In prior art, conventionally in battery case, be filled with corresponding cooling fluid or phase change material, and battery case is done to Seal Design, utilize the capacity of heat transmission of cooling fluid or phase change material to dispel the heat to battery pack, then on the architecture basics of existing battery case, it is carried out to vacuum pumping simply.After work a period of time, due to the air-tightness problem of battery pack, can make the vacuum degree of battery pack reduce, the boiling point of phase change material does not mate with the working temperature of battery pack, directly affects the radiating efficiency of battery pack.
Utility model content
The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, a kind of phase transformation battery pack system is provided, comprise that inside arranges the battery pack of the sealing of phase change material, vacuum tube and vacuum pump, in described battery pack, vacuum valve is set, one end of described vacuum tube is connected with vacuum valve, and the other end is connected with vacuum pump.
Battery pack, vacuum tube and the vacuum pump of sealing is connected to each other and forms with respect to extraneous sealing system, vacuum valve is set for connecting vacuum tube in battery pack, and controls being communicated with of vacuum tube and battery pack; Vacuum pump carries out vacuum pumping by vacuum tube to battery pack.
As preferably, the inner set temperature transducer of above-mentioned battery pack and pressure sensor, arrange control unit on described vacuum pump, and described temperature sensor is connected with control unit with pressure sensor.
At the inner set temperature transducer of battery pack and pressure sensor, to the temperature of battery pack and in compress into row monitoring in real time, then by data feedback to control unit, by control unit, control vacuum pump and whether carry out work.
As preferably, described control unit is connected with pressure sensor with temperature sensor, set temperature data and pressure data in described control unit.
Control unit is connected with pressure sensor with temperature sensor, temperature sensor and pressure sensor by the temperature of battery pack and in compress in real time monitoring of row, then feed data back to control unit, control unit is by comparing with built-in temperature data and pressure data, judge the vacuum state of battery pack, if the vacuum state variation of battery pack, need to carry out vacuum pumping, control vacuum pump and start working; Otherwise the vacuum state of battery pack is good, vacuum pump does not carry out work.
As preferably, described vacuum valve comprises single-way vacuum valve.
Use single-way vacuum valve to connect vacuum tube and battery pack, utilize its excellent one-way conduction performance, avoid extraneous gas to impact battery pack.
As preferably, described phase change material comprises hydrogen fluorine ether.
Hydrogen fluorine ether possesses good thermal stability, and safety is nonflammable, and ODP value is zero, and to ozone, without destruction, greenhouse effect are low; Moderate boiling point, boil-off gas heat-transmission is little, and drying property is good; Surface tension is little, can infiltrate micro gap; There is no ignition point, do not belong to the danger of Fire Prevention Law regulation; On the not impact of most of resin, metal, be suitable as good Heat Conduction Material.
After the technical scheme that use the utility model provides, utilize the structure of existing Packed battery pack, possess excellent vacuumizing effect, avoided the battery pack problem that sealing reduces after long-time use, in time the poor battery pack of vacuum degree is carried out to vacuum pumping; Easy and simple to handle, effect is excellent, and reliability is high.
Accompanying drawing explanation
Fig. 1 is phase transformation battery pack system schematic diagram.
1. battery pack wherein, 11. temperature sensors, 12. pressure sensors, 2. vacuum tube, 3. vacuum pump, 31. control units, 4. vacuum valve.
Embodiment
This utility model discloses a kind of phase transformation battery pack system, comprise that inside arranges the battery pack 1 of the sealing of phase change material, vacuum tube 2 and vacuum pump 3, single-way vacuum valve 4 is set in battery pack 1, one end of vacuum tube 2 is connected with single-way vacuum valve 4, the other end is connected with vacuum pump 3, the system that battery pack 1, vacuum tube 2 and vacuum pump 3 form with respect to external world's sealing, the phase change material using in this scheme is hydrogen fluorine ether.
The inner set temperature transducer 11 of battery pack 1 and pressure sensor 12, control unit 31 is set on vacuum pump 3, temperature sensor 11 is all connected with control unit 31 with pressure sensor 12, and control unit 31 can receive the feedback information of temperature sensor 11 and pressure sensor 12 detections.The interior set temperature data of control unit 31 and pressure data, temperature sensor 11 and pressure sensor 12 by the temperature of battery pack 1 and in compress in real time monitoring of row, then feed data back to control unit 31, control unit 31, by comparing with built-in temperature data and pressure data, is judged the vacuum state of battery pack 1.If the vacuum state variation of battery pack 1, need to carry out vacuum pumping, control vacuum pump 3 and start working; Otherwise the vacuum state of battery pack 1 is good, vacuum pump 3 does not carry out work.
