Embodiment
The preferred embodiment of the present invention is introduced below with reference to Figure of description, citing proves that the present invention can be implemented,
Its technology contents can be made more clear and readily appreciated to those of skill in the art's complete description present invention.The present invention
It can be emerged from by many various forms of embodiments, its protection domain is not limited only to the embodiment mentioned in text,
Figures and description herein substantially illustrates rather than the limitation present invention.In the accompanying drawings, structure identical part is with phase
Represent that the similar component of structure or function is represented with like numeral label everywhere with number designation.
The invention will be further described with reference to the accompanying drawings and examples.
As shown in figure 1, the preferred embodiment of the present invention provides a kind of echelon profit of new-energy automobile old and useless battery
With system, including：The battery bag of n capacity class identical battery modules in parallel composition, and high-voltage wiring harness, relay, guarantor
Dangerous silk, switch；In the connector that the customization of battery bag output end matches with electri forklift power input, in addition to battery control
Unit, illumination control circuit, battery control unit conversion electric power and illumination conversion electric power, will draw after multiple battery modules in parallel
Always just total minus two buses, batteries in parallel connection control unit conversion electric power and illumination conversion electric power between two buses.
In the present embodiment, illumination conversion electric power is the conversion electric power that a direct current 80V turns direct current 24V, for being controlled to illumination
System power supply processed；Battery control unit conversion electric power is the conversion electric power that a direct current 80V turns 12V, for giving battery management list
Member power supply.Also include emergency switch and wake-up switch, total positive relay and always negative relay or fill lifting motor, movable motor
Power port, battery management unit can be controlled by emergency switch and wake-up switch respectively；Two buses be connected on respectively total positive relay and
Always on negative relay, draw external interface from total positive relay and total negative relay and be used to connecting outside lifting motor, OK
Walk motor and charge port.Also include preliminary filling relay and preliminary filling resistance, total positive relay is in parallel with preliminary filling relay, prevents from filling
Charger voltage and cell voltage pressure difference are excessive during electrical initiation.Also include Y-direction electric capacity, in battery bag output end parallel connection Y-direction electric capacity
Output current is filtered.
Specifically, in the present embodiment, new-energy automobile old and useless battery bag is disassembled to obtained module, single mode group is 23 strings
2 and structure, its rated voltage is 73.6V, capacity 40Ah, and the voltage range of fork truck motor normal work be about 50 to
100V, former lead-acid battery energy storage system capacity are 560Ah, to meet the use of the normal order of classes or grades at school of fork truck, keep echelon battery and original
Energy-storage system battery capacity is equal, by n=14 modules in parallel, forms 560Ah, 73.6V, common 41.2kWh energy-storage system.
The inherent safety features of lithium ion battery are more inferior than lead-acid battery, although this programme uses relatively safer phosphoric acid
Lithium iron battery, but safe design is still the most important thing in whole scheme.Because all modules connect in parallel, and it is whole
Individual system voltage is relatively low（Compared to the high-pressure system that passenger car is more than 300V）, therefore Manual maintenance switch MSD
（ManualServiceDisconnector）It need not install.Install fuse additional（Fuse）To prevent battery bag due to interior external circuit
The danger such as excessively stream that the wrong occupation mode such as short circuit, excess load discharge and recharge triggers, overheat, burning.Consider fork truck in running
Go out in if battery leakage, smolder, fork truck collision etc. it is unexpected, answer emergency power off, therefore install emergency switch additional.
The internal resistance of lead-acid battery is much larger than lithium battery, illustrates in fork truck running, and the heating of lead-acid battery bag is much larger than
Lithium battery pack, while the operating temperature difference of lead-acid battery and lithium battery is little.Former lead-acid battery enters by the mode of natural cooling
Row radiating, thus the natural type of cooling that can similarly rely on of echelon lithium battery pack radiates, and does not produce heat accumulation, with ensure compared with
Low cost and energy consumption.
The Lighting Control Assembly of part electri forklift needs 24V low-tension supplies to be powered for it, through investigating fork truck running
The peak value electric power of middle Lighting Control Assembly is 200W, therefore is turned in a battery bag bus end 200WDC/DC direct current in parallel
Power supply is changed, input voltage range is 66 to 160V, output voltage 24V.One is drawn from DC/DC output cathodes, by customized
Terminal connector is connected with fork truck lighting circuit, is inputted as illuminator positive pole, Lighting Control Assembly negative pole and bus negative pole
Share.
Electri forklift general work needs the startup of high frequency time, slowed down, and lifting, from power output/electric current, these are dynamic
Work means instantaneous power/electric current of high frequency time, i.e. Instantaneous peak power is much larger than mean power, and transient current is much larger than average
Output current.Mode of operation accordingly, carrying out electrical equipment and wire harness type selecting by maximum current can cause super safety standard to design, cost mistake
It is high.Therefore, design of Reducing Rating can be taken to add actual condition proof method, it is ensured that security appliance reliability.It is optional by taking 3 ton forklifts as an example
The retired relay echelon of new-energy automobile for being 250A with rated current is utilized, and wire harness type selecting sectional area is 50mm2, and fuse is advised
Lattice are rated current 250A, blowout current 400A.
German REMA boards battery dedicated connector male customized（320A, IP23）, the positive and negative mother of access echelon battery bag
Line, with fitting, to realize that electric energy exports with the female at fork truck end.REMA boards dedicated connector female customized, exported with charger
Bus connects, suitable to match somebody with somebody with the connector male of battery bag.
Another aspect of the present invention provides above-mentioned new-energy automobile old and useless battery to be made for the system of electri forklift
