Do spaced second boss 221, formed recessed correspondingly with first boss 811 between two neighboring second boss 221
Groove, then first boss 811 snap in correspondingly in this groove；Similarly, the side wall internal face of upper cover body 81 also is provided with
One boss 811, accordingly the peripheral outer wall face of the side wall of upper backup pad 21 be provided with second boss 221, first boss 811 is one by one
Accordingly snap in the groove being formed between two second boss 221.As shown in figure 3, between upper cover body 81 and lower cover 82
It is additionally provided with fan 9, fan 9 is located just between outlet terminal 212 and input terminal 211, to form a complete battery
Module 1.
For two adjacent battery modules 1, the position that the outlet terminal 212 of underlying battery modules 1 is adjacent
Input terminal 211 in the battery modules 1 of top electrically connects so that being in be connected in series between two battery modules 1.Above
The upper backup pad 21 of underlying battery modules 1 that is adjacent of lower supporting plate 22 of battery modules 1 between place resistance to height
Warm thermal insulation board 4, for example, ceramic wafer or metallic plate.
As shown in Fig. 2, Fig. 9 and Figure 10, the second wiring board 10 is arranged in the top surface of the battery modules 1 of the top
On, the total input-wire end of two battery modules 1 after series connection and total leading-out terminal are all connected to the second wiring board 10, the second wiring board 10
For controlling charge status and the fault management of battery.The size of the second wiring board 10 be more than battery modules 1 size, second
The part stretching out battery modules 1 of wiring board 10 is arranged on by fixed structure in the installation cavity body in shell body 3.As Fig. 9
With shown in Figure 10, fixed structure includes the lower pillar stand 112 being molded on drain pan 31 bottom interior surface, is fixed on lower pillar stand 112 and pushes up
Upper pillar stand 111 in portion, the second wiring board 10 is arranged on the top of upper pillar stand 111, and upper pillar stand 111 and lower pillar stand 112 are
Multiple, multiple lower pillar stands 112 and upper pillar stand 111 are respectively positioned on the periphery of battery modules 1.
It is additionally provided with radiator 12 between the top surface of the second wiring board 10 and the top inner surface of top shell 32；Relay
5 are placed in drain pan 31, and charging wire is sequentially connected to relay 5, battery modules 1 and the second wiring board 10；Order wire connects

Leading-out terminal, one end that electric discharge negative line is located in shell body 3 is connected to the first end of incoming cables of the battery modules 1 positioned at bottom.
The battery bag of above-mentioned embodiment, due on the carriage assembly 2 in same battery modules 1, in each installation region
Battery on same row is connected in parallel by first conducting strip, increases the electric current in this loop, and the of adjacent two row's batteries
One conducting strip 61 is connected again, to increase the voltage in this installation region；It is conductive that battery in two installation regions passes through the 3rd again
Piece is connected, and increases the voltage in this battery modules 1 and loop current further；Meanwhile, again using string between two battery modules 1
Connection connects, and further increases voltage and the loop current of battery bag, thus improving output voltage and the output of this battery bag
Power, to form the charge and discharge mode of high input voltage and high output voltage so that the battery bag of this structure can be applied big
In the field of power apparatus, for example, welding cutting equipment, hay mover, battery-operated motor cycle etc..In charge and discharge process, when being located at
During a battery failure on same row, a battery connected in parallel is only needed to be in normal working condition it becomes possible to ensure
Circuit communication in whole battery modules 1, thus reduce the probability that battery bag breaks down.
In addition, the setting direction of polarity in installing hole 23 for three batteries on same row is identical, on adjacent two rows
The setting direction of the polarity of battery is contrary, battery overall U-shaped arrangement on carriage assembly 2, is on the one hand easy to the installation of battery
Work, on the other hand can reduce the space shared by cabling of the first conducting strip 61 in each installation region and electric wire, each
The first end of incoming cables in battery modules 1 and the first leading-out terminal are directly adjacent at the internal face of shell body 3, reduce the body of shell body 3
Long-pending so that the compact conformation of battery bag.The setting of equilibrium wiring board 7, is easy to gather the voltage of battery in each installation region at any time,
When to prevent the voltage of battery in each installation region be higher or lower than predeterminated voltage, the voltage of battery is adjusted so that battery
Voltage is in predeterminated voltage, carrys out the voltage of balancing battery, battery is played a protective role；Meanwhile, equilibrium wiring board 7 is as gear
Plate, plays position-limiting action to the installation site of battery.
The setting of radiator 12, the heat that the second wiring board 10 is given out is transferred on shell body 3 through this radiator 12,
Shell body 3 carries out heat convection again with outside air, accelerates radiating rate；The setting of fan 9, accelerates equilibrium wiring board 7 and electricity
Heat produced by pond, through carrying out the speed of heat convection with outside air, improves the radiating effect of battery bag.The setting of thermal insulation board 4
Put, when preventing the battery in underlying battery modules 1 from flame phenomenon occurring, this spray is buffered by metallic plate or ceramic wafer
Fire, it is to avoid the battery that this flame is ignited in the battery modules 1 being adjacent, thus play a protective role to battery.In addition, setting
Explosion-proof valve, it is to avoid in shell body battery modules occur explosion accident, battery bag is played safeguard protection effect.As deformation,
Explosion-proof valve only need to be arranged on the side wall of shell body.
