Embodiment
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
Below with reference to the accompanying drawings the electrokinetic cell 100 according to the embodiment of the present invention is described in detail.
Electrokinetic cell 100 according to the embodiment of the present invention can comprise: casing 10, battery core 20 and heating element 30.Battery core 20 can be multiple, and multiple battery core 20 can be sequentially arranged in casing 10 inside.Heating element 30 can be arranged in casing 10, and the contiguous whole battery core 20 of heating element 30 arranges to heat whole battery core 20 when the temperature of electrokinetic cell 100 is less than the first predetermined temperature simultaneously.Be understandable that, by arranging heating element 30, electrokinetic cell 100 can be made to heat whole battery cores 20 of electrokinetic cell 100 inside when the temperature of electrokinetic cell 100 is less than the first predetermined temperature, thus can effectively prevent electrokinetic cell 100 from use analysing lithium phenomenon, the normal use of electrokinetic cell 100 when ambient temperature is lower can be ensured, and ensure electrokinetic cell 100 charging normal when ambient temperature is lower.Wherein, alternatively, the first predetermined temperature can be-5 DEG C.
Two kinds of arrangements according to the heating element 30 in the electrokinetic cell 100 of the embodiment of the present invention are described below in detail.
The first arrangement: as depicted in figs. 1 and 2, heating element 30 can be arranged on the inner surface of diapire 11 of casing 10, and heating element 30 can be positioned at the below of whole battery core 20.In other words, heating element 30 is arranged between the inner surface of the diapire 11 of casing 10 and whole battery core 20.Thus, when the temperature of electrokinetic cell 100 is lower than the first predetermined temperature, heating element 30 can produce heat to heat the whole battery cores 20 be positioned at above heating element 30, thus the temperature of whole battery core 20 can be made to raise, can effectively prevent electrokinetic cell 100 from occurring analysing lithium phenomenon, but also the temperature consistency of whole battery core 20 can be made better, the temperature difference between battery core 20 is less, can ensure the normal work of electrokinetic cell 100 further and charge normal.
The second arrangement: heating element 30 can comprise: base plate (scheming not shown) and extension (scheming not shown), base plate can be arranged between the diapire 11 of battery core 20 and casing 10.Between adjacent battery core 20, interval is arranged, and extension can be multiple, and multiple extension can extend upwardly in the gap between two adjacent battery cores 20 respectively.That is, the heating element 30 of this kind of arrangement is provided with multiple extension on the heating element 30 of the first arrangement.By arranging multiple extension in base plate, can make when the temperature of electrokinetic cell 100 is lower than the first predetermined temperature, extension can heat the battery core 20 being positioned at extension both sides preferably, thus the efficiency that heating element 30 heats battery core 20 can be improved further, accelerate electrokinetic cell 100 normally work or charge normal the time needing to wait for, but also the consistency of the temperature of whole battery core 20 can be improved further, improve the design rationality of electrokinetic cell 100.
Wherein, alternatively, the extended height of extension is at least height over half of battery core 20.Preferably, the extended height of extension can be identical with the height of battery core 20, thus extension can be made effectively to heat the whole side surface of the battery core 20 adjacent with extension, improve the efficiency that heating element 30 heats battery core 20 further, improve the temperature consistency of whole battery core 20.
According to the electrokinetic cell 100 of the embodiment of the present invention, by arranging the heating element 30 of contiguous whole battery core 20, can in the temperature of electrokinetic cell 100 lower than effectively heating whole battery core 20 during the first predetermined temperature, ensure the normal work of electrokinetic cell 100 and charge normal, but also the temperature consistency of whole battery core 20 can be ensured, reduce the temperature difference between battery core 20, ensure the good working state of electrokinetic cell 100.
In examples more of the present invention, the thickness of heating element 30 can between 0.5mm ~ 2mm.Thus, it is less that the heating element 30 meeting above-mentioned thickness condition takies casing 10 inner space, and (such as the battery core 20) of being convenient to miscellaneous part in casing 10 is arranged, and improves the space connection and reasonable arrangement of electrokinetic cell 100.Preferably, the thickness of heating element 30 can be 1.0mm.
In concrete examples more of the present invention, heating element 30 can be electrical heating elements, and heating element 30 can be arranged in battery core 20 temperature higher than power-off during the second predetermined temperature and allow battery core 20 charge.Be understandable that, when the temperature of electrokinetic cell 100 is lower than the first predetermined temperature, heating element 30 starts to heat whole battery core 20, and when the temperature of battery core 20 is higher than the second predetermined temperature, heating element 30 power-off is to stop the heating to whole battery core 20.After heating completes, electrokinetic cell 100 can charge, thus electrokinetic cell 100 charging effect can be made good.Alternatively, the second predetermined temperature can be 10 DEG C.
Alternatively, heating element 30 can be electric heating sheets, but is not limited thereto.
Wherein, it should be noted that, as shown in Figure 2, between the diapire 11 of heating element 30 and casing 10, insulating barrier 40 can be provided with, thus effectively can improve the safety in utilization of electrokinetic cell 100.
According to the vehicle of the embodiment of the present invention, comprising: the electrokinetic cell 100 of charger, above-described embodiment, temperature sensor and controller.Charger is connected with heating element 30 with battery core 20 respectively, temperature sensor is arranged on electrokinetic cell 100 to detect the temperature of battery core 20, controller is connected with temperature sensor with charger respectively, and whether controller can control charger according to the testing result of temperature sensor and power to heating element 30.Charger can charge in battery core 20, also can power to make heating element 30 produce heat in heating element 30.When the testing result that temperature sensor detects battery core 20 is less than the first predetermined temperature, controller can control charger and power in heating element 30, heating element 30 produces heat to heat battery core 20, thus the temperature of whole battery core 20 can be made to raise with more than the first predetermined temperature; When the testing result that temperature sensor detects is greater than the second predetermined temperature, controller controls charger to be stopped powering to make heating element 30 stop heating battery core 20 to heating element 30, now, controller can optionally control charger according to the electricity of electrokinetic cell 100 and charges to electrokinetic cell 100.Such as when electrokinetic cell 100 electricity is lower and when being less than predetermined electricity, controller can control charger and charge in electrokinetic cell 100.
According to the vehicle of the embodiment of the present invention, comprise the electrokinetic cell 100 of above-described embodiment, the normal work of electrokinetic cell 100 can be ensured and charge normal, and the temperature consistency of whole battery core 20 can be ensured, thus the good working state of electrokinetic cell 100 can be ensured.
