DE 100 18 456 describes a kind of low pressure feedway, its charging device parallel operation being connected with power network. This low pressure feedway is supplied according to the quantity of the battery in parallel with stratie, the size of these straties Match to the size of battery and the driving battery of electric vehicle can be made to realize insulation according to optimal condition of work is corresponding.
DE 196 14 435 have studied a kind of battery, and it has the charging device and heating dress matched with the battery Put.Whole individual equipments is persistently arranged in a shell heat-insulatedly.Heater is by heating element heater and for measuring and adjusting The temperature-adjusting device for saving the temperature of housing interior volume is constituted.To the energy supply of heating element heater herein by generally with battery or The electrical connection of the output end of charging device is realized.
The content of the invention
A kind of battery and the motor vehicle with the battery are proposed according to the present invention.Battery is included in thermally insulating housing at least One battery battery core, wherein, electrical heating elements and thermostat are additionally provided with shell, and electrical heating elements and thermostat are logical Overregulate device to be so connected with each other, i.e. heating element heater is when being cooled to or less than prespecified minimum temperature with this degree Heating so that minimum temperature is maintained or reaches again.Battery is characterised by that heating element heater is embodied as flexible-belt.
Heating element heater can so be closely arranged on battery battery core and battery battery core is therefore efficiently heated.
In one embodiment, battery includes at least two battery battery cores and heating element heater is at least partially disposed on Between battery battery core.
It is possible thereby to make module obtain more efficient heating.
Adjuster can be integrated into the electronic-controlled installation of battery or battery management system herein.
Now, adjuster can suitably be realized with compact and cost.
Or PTC resistor includes heating element heater and adjuster.
This abnormal cost is suitable and simply realizes heating element heater and adjuster.
Heating element heater can be by least one battery battery core energy supply.
Now, the temperature treatment of battery is unrelated with the charge power supply of outside.
Here, can by by the energy supply of at least one battery battery core be defined as battery not with the outside for being charged for battery Power supply is carried out in the case of connecting.
This prevents the unnecessary electric discharge of battery battery core.
Additionally, adjuster may be designed at least using at least one battery when being supplied by least one battery battery core Determine the duration of heat in the case of the charged state of battery core.
This prevents the unnecessary electric discharge of battery battery core.
Additionally, adjuster may be designed to also using ambient temperature and/or in the case of the user-defined duration really Determine the duration of heat.
This prevents the unnecessary electric discharge of battery battery core.
In the implementation method that a kind of battery can be cooled down by cooling system, can be prevented in heating element heats Cooling.
This can be such that battery battery core is efficiently heated.
Even if according to prior art operating temperature can caused to be reduced to most in vehicle according to vehicle proposed by the present invention Cause below low temperature and therefore still to keep its whole service behaviour under the environment temperature that service behaviour is restricted.
The scheme that is advantageously improved of the invention is explained in the description.
Brief description of the drawings
Embodiments of the invention are described in detail by accompanying drawing and following description now.Wherein：
Fig. 1 shows the outside drawing of the one embodiment according to battery of the invention；
Fig. 2 shows the profile of shown battery in Fig. 1；And
Fig. 3 shows the profile according to another embodiment of battery of the invention.
Specific embodiment
Fig. 1 shows the outside drawing of the one embodiment according to battery of the invention 1.The shell of battery 1 has lead, its Realize the electrical contact with the battery battery core of battery.For example, a battery battery core or multiple battery battery cores can be connected to high-tension electricity On net or low voltage electric network.
Fig. 2 show in section battery 1 shown in Fig. 1.There are multiple battery battery core 3-1...3-n in internally, But unique battery battery core is also feasible.Also having in internally is used for the adjuster of electronic installation and logic circuit-exactly 4th, the region of heating element heater 6 (such as the resistance of the also referred to as PTC resistor with positive temperature coefficient) and temperature sensor 7-.Electricity Pond battery core 3-1...3-n is arranged in the shell 1-1 by cover closure, wherein, shell and cover plate have thermal insulation barriers 5.Heating unit Part 6 is embodied as the flexible-belt in the inside of battery 1 herein.
Figure 3 illustrates the implementation method of another exemplary of the invention.In this heating element heater 9 around battery battery core 3- 1...3-n wind and be more particularly set between battery battery core 3-1...3-n.Additionally, heating element heater can be as in the example It is distributed as shown.
Minimum temperature T is reduced to for ambient temperature0Following situation, by make heating element heater 6 or 9 with for example using Be maintained above for the temperature of the battery battery core in encapsulant (Pack) inside by the connection of thermoregulator 8 that pid algorithm is realized Minimum temperature T0.Saved land for this is modulated by adjuster 8 either from battery battery core, or accurate from outside power supply to heating element heater Really convey appropriate power.Heating element heater is so disposed herein, i.e. its heat is only used for battery battery core as far as possible, and to the greatest extent Heat therein may less be lost, and battery battery core need not be heated, that is, the centre for example between battery battery core.
Because the capacity of heat transmission of the material in the inside of the battery of also referred to as batteries is substantially better than thermal insulation barriers Capacity of heat transmission, and required heating power is at a fairly low, so heating element heater placement is wherein less important.Adjust Section device 8 can be integrated into other electronic-controlled installations of batteries or battery management system.
If heating element heater is PTC resistor, then the element can automatically adjust temperature.
Thermal insulation barriers are depended on for the necessary heating power of the temperature difference pursued between operating temperature and environment temperature Thickness and lead to battery electric lead cross section.If cross section is about 250mm2And thickness is about 5cm, then according to One battery of one embodiment needs 100 watts of heating power, to ensure the temperature difference of 20 Kelvins.
In one embodiment, prevent cooling from keeping away by by adjuster 8 or electronic-controlled installation or battery management system Exempt from heat to be lost by unshowned battery cooling system in the accompanying drawings.
In the case where vehicle is not connected with charging conductor, the power for heating element heater 6 can be derived from battery battery core 3-1...3-n。
Now can for advantageously, in the case of using the charged state of the battery battery core 3-1...3-n of battery 1 when Between the upper limitation duration of heat, to prevent over-discharge.
Except charged state, using ambient temperature or environment temperature and/or driver looking into duration for stopping Ask to limit the duration of heat, to prevent over-discharge.
