Embodiment
It will carry out implementing full and accurately using one of which technical scheme in patent embodiment of the present invention.If it is by dry cell batteries
Arrange and be fixed on inside Battery case in order, can be connected between each battery pack can also be in parallel.Each Battery case
It is made up of 6 battery packs, temperature controller, 4 radiator fans, 4 temperature sensors, battery management system, 8 blocks of heat sinks.
Each battery pack is by single battery group, 8 pieces of TEC thermoelectric slices, battery packs.Battery pack is made up of 9 section monocells.It is every two section monocell it
Between be connected one section of fuse, the fuse is arranged on monocell in the small-rabbet that covers, is also connected between each two battery pack
One section of fuse, this is insurance module part.Further design connected mode is as follows wherein between each main modular：
One, battery modules：Because the size of 18650 monocells is diameter in 18mm or so, length is left in 65mm
The right side, therefore be fixed together composition single battery group using thermal shrinkable sleeve or close mode from 9 section lithium batteries in patent of the present invention,
Battery pack is constituted by battery again.Temperature controller is connected in the total anode and total negative terminal of battery pack in addition, monocell is carried out
Protection.Often section li battery shell is coated with the cushion such as heat conduction but the paper tape of insulation, can not only protect monocell from damage
Hinder and short circuit can be prevented and produced dangerous.
Two, insurance modules：Each batteries have single fuse to be linked in battery pack, to prevent single battery mistake
Heat and jeopardize integral battery door overheat；When the too high rated value more than fuse of temperature occurs in single battery, fuse will be automatic
Fuse to protect whole battery pack.Each battery pack and Battery case are connected outside the total fuse of a section, total fuse in addition
One shell of set is protected.It will be welded per batteries fuse finely, to prevent loose contact or high pressure height from miscarrying
Raw harm.
Three, temperature control modules 1：In each battery pack, lid, bottom monocell pallet, 8 pieces of TEC thermoelectric slices on monocell
Constituted temperature control module 1.Because the size of TEC thermoelectric slices is 40 × 40 × 3.8mm or so, thus it is single in the bottom of battery pack
It is single that the side of cylindrical shell and battery-pack exterior casing in battery tray is glued with lid and bottom on 8 pieces of TEC thermoelectric slices, monocell
Battery tray is constituted by the good metal alloy of heat conductivility, constitutes a unified entirety.When the temperature of battery pack is higher than
During the temperature of external environment, convey to temperature controller by 4 temperature sensors in the outside in Battery case and carry out
Arrange and analyze, the sense of current of TEC thermoelectric slices is flowed through by all buses and polygon control survey that concentrate in Battery case, is made
TEC thermoelectric slices nestle up that face refrigeration of battery, so as to produce a refrigeration to whole single battery group；If otherwise battery
When the temperature of group is less than the temperature of external environment, the sense of current of TEC thermoelectric slices is flowed through by control, TEC thermoelectric slices are abutted
That face heat production of battery, so as to produce a heating effect to whole single battery group.But these are all temperature controls to be leaned on
The Reasonable Regulation And Control of device processed and scheduling, different grades are divided into different temperature ranges, when freeze when heat production when not
Work is needed to have a clear and definite line of demarcation.
Four, temperature control modules 2：In each Battery case, by temperature controller, 4 radiator fans, 8 blocks of heat sinks, 4
Temperature sensor constitutes temperature control module 2.8 blocks of heat sinks are made up of the good metal alloy plate of heat conductivility, and its two sides is all
It is close to TEC thermoelectric slices.When the temperature of battery pack is higher than the temperature of external environment, the heat of the hot junction generation of TEC thermoelectric slices
By radiating, plate module can be conducted quickly.At the same time, the data conducted according to temperature sensor, temperature controller enters
Row comprehensive analysis and the duration of runs of control radiator fan and rotating speed, the conduction of accelerated heat after processing.
