Detailed description of the invention
As shown in Fig. 1 to Figure 15, for existing defect, the protection main body of the present invention is as follows:
Exploitation is a kind of lithium cell electrokinetic cell bag, and existing cylinder type lithium battery exists two kinds of feelings in installation process
Condition, one is directly to use film material to bundle, and forms electrokinetic cell bag, and this electrokinetic cell bag there is problems of,
Easily accumulate heat, cause temperature to raise, self-expanding, leakage, spontaneous combustion, self-destruction, poor stability, for this problem, existing
Solution is, increases a framework, and it is still obvious that existing framework has phenomenon of expanding with heat and contract with cold, such as Chinese patent
The scheme announced in CN204927374U, its medium-height trestle uses moulding, has insulation and the effect of location, can facilitate cylinder
The assembling of shape lithium battery, but, above-mentioned structure is formed without air channel, and the heat radiation for battery core the most fundamentally solves, and deposits
In problems with: support is working of plastics, having inflammable characteristic, although plastic density is lower than metal, but support is solid,
Deadweight is relatively big, accounts for about 1/10th of battery core weight, and additionally antidetonation defening effect is the most bad.
Technical barrier to be solved is:
A difficult problem one: during electrokinetic cell works, single battery core exists flatulence of heat type effect, and the swell increment of multiple battery cores is accumulated at
Battery is wrapped, and will form huge deformation, and causing the dislocation of electrode position, current solution is that electrode design becomes U
Type, for making up the displacement between battery core and deformation.
A difficult problem two: in the case of single battery core is short-circuited, due to be proximate between battery core, do not have support carry out every
From, and the material of battery core and busbar is lithium material, and high temperature own is inflammable, can cause adjacent between the detonation of battery core.
A difficult problem three: cooling wind is in unordered flow regime, it is impossible to effectively lower the temperature for battery core, it is impossible in battery core
It is formed about uniform wind field, the non-uniform temperature at each battery core, cause battery core internal resistance inconsistent, power consumption increases.
A difficult problem four, from great, the density of lithium electricity battery core own is big, adds metal shell, and deadweight is bigger, deadweight account for vehicle body from
More than half of weight.
