Embodiment
A kind of lithium battery that can be used in low temperature environment of the present embodiment, including lithium battery group 1 and battery case 2, lithium
Battery pack 1 is arranged in battery case 2 in cellular, and heat conduction is set between lithium battery group 1 and between lithium battery group 1 and battery case 2
Material 3；The outside of conduction material 3 sets carbon fibre heating cloth 4, and carbon fibre heating cloth 4 mainly includes carbon fiber exothermic part, battery case
2 housing outer layers are thermal insulation layer 5；Set in lithium battery group 1 and detector unit 7, electricity sensing are set on protection board 6, protection board 6
Device 8, microprocessor and control module, the surface of battery case 2 set discharge connection mouthful 9, charging connection jaws 10, the and of status indicator lamp 11
Shift knob 12；Microprocessor connection detector unit 7, electrical quantity sensor 8, shift knob 12 and control module, control mould
Block connects carbon fibre heating cloth 4 and status indicator lamp 11；In a tubular form, carbon fiber exothermic part mainly includes by carbon carbon fiber exothermic part
The heating body of fibrous material cladding heating wire formation；Discharge connection mouthful 9 connects the discharge circuit inside battery case 2, charging
Line mouthful 10 connects the charging circuit inside battery case 2；Charge-discharge circuit inside the connection battery case 2 of shift knob 12；Heat conduction thing
Matter 3 is conduction oil；Electronic switch, control module connection electronic switch are set on the discharge and recharge power bus of lithium battery group 1；Carbon is fine
Dimension electrothermal cloth 4 is arranged on the interior side-wall surface of battery case 2, and uniformly cladding is arranged in outside conduction material 3 carbon fibre heating cloth 4；Temperature
Degree detecting element 7 is NTC thermistor, and the B values of detector unit 7 are that 3435K, resistance value are 10K.
When battery will be at low temperature in use, first have to open shift knob 12 on battery case 2, this shift knob 12 is to add
Thermal switch.The built-in temperature sensor 7 of protection board 6, when detecting internal temperature of battery less than 10 DEG C, now status indicator lamp 11
In amber light it is bright, lithium battery group 1 can be powered to carbon fibre heating cloth 4, carbon fibre heating cloth 4 generate heat and by lithium battery group 1 outside
The conduction material 3 of portion's filling conducts heat to lithium battery group 1, the internal temperature of lithium battery group 1 is lifted, when the temperature of lithium battery group 1 reaches
Microprocessor controls carbon fibre heating cloth 4 to power off by control module on to protection board 6 at 25 DEG C, stops heating；While battery
The thermal insulation layer 5 of the shell of case 2 effectively preserves heat, and now the green light in status indicator lamp 11 represents that battery can normally make
