Description
Technical field
The present invention relates to a kind of lithium dynamical battery modules, exactly, are related to a kind of safe lithium dynamical battery mould of overall process
Block.
Background technique
Using the electric car spontaneous combustion safety accidents even on fire from explosion etc. frequent occurrence of lithium battery driving, trace it to its cause general
Cause all over assert that lithium battery itself is dangerous, but obvious logical problem is that the gasoline of burning is undoubtedly more dangerous, number
Automobile in terms of hundred million is all on the way run daily, and structure is also extremely complex compared with existing electric car, one in science judgment
It surely is not worship the unique property of lithium battery in structure design aspect rather than simply draw a conclusion and shirk responsibility.
Existing lithium battery power assembly design logic generallys use large-scale integrated mode, and foundation is that complete vehicle weight is flat
Weighing apparatus is managed convenient for heat pipe sealed, by crash requirements etc., and there is also be further improved the sky promoted from the point of view of practical effect
Between, for example, when by sharp impacts to be still deformed short circuit on fire from explosion for battery, can still go out since algorithm is not scientific
Existing internal short-circuit causes spontaneous combustion, and the technology path for continuing to use fuel-engined vehicle simply increases continual mileage, causes to include charging system
Stability, the reliability decrease of numerous systems inside are artificially produced because system designs unreasonable initiation safety accident.
The safe lithium dynamical battery module of overall process of the present invention changes present common practice, by the battery of a monolith
Assembly is divided into the series-parallel combination of international standard safe voltage module, even if meeting with the environmental impact of most serious, hard electricity
Pressure security module can only scatter and will not deform, and the dynamic change trend of each battery core of inside modules is regular to be followed, once occur
Exception can give warning in advance in time, and modular manner is more convenient for producing mobile, maintenance, and assembly system modes selecting is more
Flexibly, the relatively reliable safety of whole system.
Summary of the invention
The present invention relates to a kind of safe lithium dynamical battery module of overall process, 48 volts of specified human safety voltage, Soft Roll lithium electricity
Pond battery core in groups after together with sensor, data line and power cable are unified be cast for firm module with professional glue, professional glue is ring
Oxygen resin, silica gel or polyurethane, sensor and data line are completed in module service life overall process to module operating temperature, electricity
The real-time record of the modules operating history such as core operating voltage, realizes the dynamic safety monitored control of module.
Current invention bring the advantage that changing present traditional method, the battery assembly of a monolith is divided into international mark
The series-parallel combination of quasi- safe voltage module, even if meeting with the environmental impact of most serious, hard voltage security module can only dissipate
Opening will not deform, and the dynamic change trend of each battery core of inside modules is regular to be followed, once be abnormal to shift to an earlier date in time
Early warning, modular manner are more convenient for producing mobile, maintenance, and assembly system modes selecting is more flexible, and whole system is more
Add reliable and secure.
Inventive embodiments.
The present invention is further illustrated below by a specific embodiment.
Fig. 1 is module one embodiment structural schematic diagram of the present invention.
Fig. 2 is module safety control principle drawing of the present invention.
Fig. 3 is that module of the present invention puts figure on automobile chassis.
In figure, 10: soft-package battery group；20: module safety control system；30: output voltage acquires conversion unit circuit；
40: battery temperature acquisition unit circuit；50: data processing transmission unit circuit；60: electronic tag unit circuit；70: charge and discharge
Interface；80:48 lies prostrate lithium dynamical battery module；90: automobile chassis battery flat.
The present embodiment is an electric taxi, 48 volts of lithium dynamical battery modules shown in Fig. 1, inside with hardness D85 with
On ethoxyline resin antiflaming glue soak entirely and melt totally 26 soft pack cells, temperature sensor, each battery core voltage have been adopted before casting
Collection data line and the power cable at total output both ends are connected on module safety control system (20) plate, the peace of module shown in Fig. 2
Full control system entirely uses in life cycle in the operating of module electric energy, and battery pack is in safety monitoring state, output voltage always
Acquire every battery core voltage change of conversion unit circuit (30) real-time monitoring, battery temperature acquisition unit circuit (40) real-time monitoring
These data can be kept records of and independently be divided by battery pack temperature variation, data processing transmission unit circuit (50)
Analysis, electronic tag unit circuit (60) assign exclusive identification code before each battery pack qualification is dispatched from the factory, when going out in battery use process
When now abnormal, clear data record can be generated by peripheral system early warning relevant people, at an electric taxi bottom shown in Fig. 3
Disk battery flat (90) symmetrically puts 14 48 volts of lithium dynamical battery modules (80), the power cable directly company of plug between module altogether
It connects, 27 ampere-hour of battery core capacity, each 2500 watt-hour of module capacitance amount, volume is less than 8 liters, and 15 kilograms of weight or so, 48 volts belong to
Human safety voltage, when production is mobile and maintenance can safety operation, module carried out various extreme peaces before volume production
Complete test, including it is fully charged after carry out intensive gunslinging safety test, Engineering Design overall goal considers most dangerous several
Kind extreme situation, such as when encountering sharp impacts, 336 volts of high pressure of battery assembly can be shattered into 48 volts of security modules, and module is different
Chang Jiangu has buffer area not deform again, when encountering flood inundation on tracks, module short circuit give out light naturally electric energy become safety, short-circuit mistake
The journey time it is of short duration its own have high-temperature resistance, when encountering gunslinging bullet be enclosed in inside modules be unable to undergo what effect,
In terms of selection of charging, it both can choose directly plug and changed electricity, and also can choose roadside charging pile quick charge, battery assembly can
It is charged with 3C, the charging time is only 15 minutes or so.
