Description
Technical field
The present invention relates to the air-cooled type lithium battery pack heat management systems and method of a kind of high-protection level, belong to electric car
Battery pack field of radiating.
Background technique
The heat management of lithium battery pack is not only most important to battery life, also most important to the safety of battery.
Traditional battery pack thermal management algorithm --- air cooling technique is not able to satisfy wanting for the degree of protection of lithium battery pack not only
It asks, and since the air cooling system inlet and outlet temperature difference is big, causes the biggish temperature difference between battery core and battery core, the injury to lithium battery
Greatly, therefore at present it sees substantially without use value.
Traditional lithium battery pack thermal management algorithm with high-protection level generally uses liquid cooling mode, at present major part factory
Single liquid cooling plate is only arranged in the bottom of battery modules in the liquid cooling bottom plate that family uses, and the single liquid in the bottom of battery modules
Cold plate radiating mode will cause temperature difference very big up and down inside battery cell, right in fast charging and discharging and low-temperature prewarming
The injury of battery is larger.Only tesla uses the full side surface liquid cooling mode of all batteries.But current liquid cooling medium is using antifreeze
Liquid or refrigerant are directly cooling, and the latter is equivalent to direct-expansion type evaporator.Refrigerant direct-expansion type is cooling due to refrigerant
Temperature is too low, will cause serious cold shock to battery and causes the great temperature difference of inside battery, causes to battery very big
Injury does not have practical value substantially yet.Using it is more be anti-icing fluid, contain water in anti-icing fluid, for the liquid more than welding position
Cold bottom plate, in use, welding position are easy breakage, and internal anti-icing fluid is caused to be revealed；Full side is used for tesla
Face is to liquid cooling pipe, although soldering opening is located at battery pack to outside, once hitting, the liquid cooling tube damage between battery core can also be made
It is revealed at anti-icing fluid, and soldering opening is distributed in full side, the probability that soldering opening is destroyed is big.No matter which kind of situation, leakage is prevented
Freezing liquid can make battery pack short-circuit if contacting with the battery in battery pack, can all cause serious safety accident.
In addition, no matter which kind of liquid cooling mode, the refrigeration system of active is dependent on, for dynamic lithium battery on electric car
Packet, once parking shutdown, liquid cooling system will be completely in off-mode, and the local thermal runaway of battery is often in parking of automobile
Occur when state, dieseling of the recurrent electric car in parking be mostly caused by thermal runaway, this when
Heat management system does not work.And most of thermal runaway is caused due to battery local temperature heating (factors such as impurity) overheat
Caused by the destruction of battery core internal expansion causes short circuit, therefore thermal runaway in such cases is difficult to avoid.
In addition, current liquid cooling system is not energy-efficient, because no matter what season to open electric vehicle in, as long as battery
Temperature is higher than setting value, such as 35 DEG C -42 DEG C, and refrigeration system requires to open heat dissipation, and refrigeration system needs to consume more battery
Storage.
