The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description only to explain the utility model, is not used to limit the utility model.
As shown in figure 1, a kind of new type lithium ion battery group, has housing 10, lithium ion battery 20 and protection circuit plate 30,
Housing 10 includes lower drain pan 11 and cap 12, in the bottom of lower drain pan 11 formed with battery case 110, is housed in battery case 110
There is lithium ion battery 20, protection circuit plate 30 is connected with one end of lithium ion battery 20, protection circuit plate 30 is arranged on bottom
On one side panel 112 of shell 11, formed with contact 31,32 on protection circuit plate 30, contact 31,32 is from forming in side panel
Through hole 111 on 112 is to exposing outside.In battery discharge, contact is output contact, and when being charged to battery, contact is input
Contact.It is prior art above, refers to patent CN201420807511.X files.
Wherein, there are heater element 33, the heater element 33 and the installation side of lower drain pan 11 on the protection circuit plate
The phase-change material layers 34 with temp regulating function are provided between the inwall of side panel 112.
Due to the more than one of heater element 33 on protection circuit plate, if any the adjustment of the power tube, power supply of circuit final stage
Pipe, dropping resistor etc., therefore, the corresponding heater element are corresponding in each heater element and lower drain pan 11 also to be multiple
Phase-change material layers 34 are set between the inwall of the side panel 112 of installation side.
Wherein, the phase-change material layers 34 are to be attached to the thin slice on heater element surface, its thickness 3-5 millimeters.
Wherein, the phase-change material layers 34 accordingly fix estersil using corresponding fixed estersil such as Laird.
The utility model is provided with phase-change material between the heater element on circuit board and the corresponding side wall of shell so that
Heat caused by heater element can be absorbed by phase-change material, and can be delivered to by battery-pack exterior casing outside battery pack, be protected
The radiating effect of discharge prevention plate is demonstrate,proved, is advantageous to strengthen the reliability of battery supply.
Further, insulation board 36 and cushion pad 35 are provided between the protection circuit plate and lithium ion battery 20,
Wherein, the cushion pad is offered on insulation board 36 and cushion pad 35 and is used between insulation board and protection circuit plate
Lithium so passes through the insulation board 36 and cushion pad from the corresponding connection through hole 37 that electronic cell makes electrical contact with protection circuit plate
35 setting, after the lithium ion battery 20 electrically connects with protection circuit plate, when shaking or by external impact, it can guarantee that
