Specifically, in the present embodiment, module new-energy automobile old and useless battery packet disassembled, single mode group are 23 strings
2 and structure, rated voltage 73.6V, capacity 40Ah, and fork truck motor work normally voltage range be about 50 to
100V, former lead-acid battery energy storage system capacity are 560Ah, to meet the use of the normal shift of fork truck, keep echelon battery and original
Energy-storage system battery capacity is equal, by n=14 modules in parallel, constitutes 560Ah, 73.6V, the energy-storage system of total 41.2kWh.
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 entire scheme.Since all modules connect in parallel, and it is whole
A 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 pack due to interior external circuit
The danger such as overcurrent, overheat, the burning that the mistake occupation mode such as short circuit, excess load charge and discharge causes.Consider fork truck in operational process
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 operational process, the fever of lead-acid battery packet 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 by natural cooling mode into
Row heat dissipation, thus the also the same of echelon lithium battery pack is radiated by the natural type of cooling, and does not generate heat accumulation, with ensure compared with
Low cost and energy consumption.
The lighting control system of part electri forklift needs 24V low-tension supplies to power for it, through investigating fork truck operational process

Terminal connector is connect with fork truck lighting circuit, is inputted as lighting system anode, lighting control system cathode and busbar cathode
It shares.
Electri forklift general work needs the startup of high frequency time, slows down, and lifting, from output power/electric current, these are dynamic
Work means that instantaneous power/electric current of high frequency time, i.e. Instantaneous peak power are much larger than mean power, and transient current is much larger than average
Output current.Operating mode accordingly, carrying out electric appliance and 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 utilizes, and harness type selecting sectional area is 50mm2, fuse rule
Lattice are rated current 250A, blowout current 400A.
Germany REMA boards accumulator dedicated connector male connector customized（320A, IP23）, access the positive and negative mother of echelon battery pack
Line, with fitting, to realize electric energy output with the female at fork truck end.REMA boards dedicated connector female customized is exported with charger
Bus connects, suitable to match with the connector male connector of battery pack.
