In some embodiments of the present invention, referring to fig. 1, the heating device 2 includes a temperature control component 21 and a heating component 22, where the temperature control component 21 is used to control the heating component 22 to heat the energy storage battery 11, it is understood that the heating component 22 may be disposed inside the energy storage battery 11 or outside the energy storage battery 11, the heating component 22 may exchange heat with the energy storage battery 11, the heating component 22 generates heat after being electrified to heat the energy storage battery 11, and the temperature control component 21 may control the heating power and time of the heating component 22 to control the temperature of the heating component 22 and the temperature of the energy storage battery 11, so as to avoid that the temperature of the energy storage battery 11 is too low to affect the charging and discharging performance, and avoid that the temperature of the heating component 22 and the temperature of the energy storage battery 11 are too high to cause a safety accident.
In some embodiments of the present invention, the temperature control assembly 21 is further configured to determine a temperature adjustment mode of the temperature control assembly 21 prior to controlling the heating assembly 22 to heat the energy storage battery 11. The temperature control mode of the temperature control assembly 21 can be selected by a user, the temperature control assembly 21 can be provided with a knob for selecting the temperature control mode, and the temperature control modes selectable by the knob are as follows: a thermostat mode, a manual thermostat mode, and a shut-off mode, and a user can switch the thermostat mode of the temperature control assembly 21 by rotating the knob.
When the temperature control assembly 21 is in the automatic temperature adjustment mode, the temperature control assembly 21 controls the heating assembly 22 to automatically heat the energy storage battery 11, so that the temperature of the energy storage battery 11 is maintained within a preset temperature range, performance degradation of the energy storage battery 11 in a low-temperature environment is avoided, and charging and discharging performances of the energy storage battery 11 are guaranteed. Optionally, the preset temperature range is 0 ℃ to 5 ℃, when the temperature of the energy storage battery 11 is lower than 0 ℃, the temperature control component 21 controls the heating component 22 to heat the energy storage battery 11, and when the temperature of the energy storage battery 11 is higher than 5 ℃, the temperature control component 21 controls the heating component 22 to stop heating the energy storage battery 11.
When the temperature control assembly 21 is in the manual temperature adjustment mode, the temperature control assembly 21 controls the heating assembly 22 to continuously heat the energy storage battery 11, so that when the ambient temperature is extremely low, the heating assembly 22 always keeps heating the energy storage battery 11, and larger temperature fluctuation caused by too fast heat exchange between the energy storage battery 11 and the external environment is avoided, so that the stability of the energy storage battery 11 is improved.
It should be noted that, the temperature control component 21 may communicate with a BMS (battery management system) of the energy storage battery 11 to obtain parameters such as a temperature and a remaining power of the energy storage battery 11. When the temperature control assembly 21 is in the automatic temperature adjustment mode or the manual temperature adjustment mode, if the temperature of the energy storage battery 11 is greater than a sixth preset temperature, the temperature control assembly 21 may stop the heating of the energy storage battery 11 by the heating assembly 22, wherein the sixth preset temperature is T6, the first preset temperature is T1, T6 and T1 satisfy the following relationship, t6=t1+t0, and t0.ltoreq.t0.ltoreq.10deg.C.
For example, the first preset temperature is 0 ℃, and the sixth preset temperature is 5 ℃ or 8 ℃, so as to reduce the energy consumption of the heating assembly 22 when the energy storage battery 11 reaches the proper temperature.
When the temperature control assembly 21 is in the off mode, the temperature control assembly 21 controls the heating assembly 22 to inhibit heating of the energy storage battery 11, so that the heating function of the heating assembly 22 can be turned off in an emergency, and the safety of the heating device 2 is improved.
In some embodiments of the present invention, the temperature control assembly 21 is further configured to determine a power supply device for supplying power to the heating device 2 before controlling the heating assembly 22 to heat the energy storage battery 11, and the temperature control assembly 21 may communicate with the control device 3 to determine the power supply device for supplying power to the heating device 2.
When the power supply device for supplying power to the heating device 2 is the energy storage battery 11, the temperature control component 21 controls the heating component 22 to heat the energy storage battery 11 to a first preset temperature. When the power supply device for supplying power to the heating device 2 is not the energy storage battery 11, the temperature control component 21 controls the heating component 22 to heat the energy storage battery 11 to a second preset temperature. The first preset temperature is lower than the second preset temperature, so that when the energy storage battery 11 supplies power to the heating device 2, the energy storage battery 11 can be heated to the first preset temperature with lower temperature, so that the electric energy consumption of the heating component 22 is reduced, and the endurance time of the energy storage battery 11 is prolonged. When one of the first external power supply socket 13, the solar panel 12 and the second external power supply socket 14 supplies power to the heating device 2, the energy storage battery 11 can be heated to a second preset temperature with higher temperature, so that the energy storage battery 11 can be in an optimal working temperature range, and the charge and discharge performance and the service life of the energy storage battery 11 can be improved.
For example, the first preset temperature is 0 ℃, the second preset temperature is 5 ℃, and when the power supply device for supplying power to the heating device 2 is the energy storage battery 11, the temperature control component 21 controls the heating component 22 to heat the energy storage battery 11 to 0 ℃ and then stops heating, so as to reduce the power consumption of the heating component 22. When the power supply device for supplying power to the heating device 2 is not the energy storage battery 11, the temperature control component 21 controls the heating component 22 to heat the energy storage battery 11 to 5 ℃ and then stops heating so as to improve the charge and discharge performance and the service life of the energy storage battery 11.
In some embodiments of the present invention, the temperature control component 21 is further configured to obtain the temperature of the energy storage battery 11 and the external environment temperature in real time, and when the heating component 22 is controlled to heat the energy storage battery 11 to the first preset temperature:
if the external ambient temperature is less than or equal to the third preset temperature, the heating assembly 22 is controlled to heat the energy storage battery 11 at intervals according to the first heating beat until the temperature of the energy storage battery 11 reaches the first preset temperature. If the external environment temperature is greater than the third preset temperature and less than the fourth preset temperature, the heating assembly 22 is controlled to heat the energy storage battery 11 at intervals according to the second heating beat until the temperature of the energy storage battery 11 reaches the first preset temperature, wherein the third preset temperature is less than the fourth preset temperature, and the heating time of the first heating beat is greater than the heating time of the second heating beat, so that when the energy storage battery 11 supplies power to the heating device 2, the heating beat of the heating assembly 22 can be adjusted according to the temperature of the energy storage battery 11 and the external environment temperature of the heating assembly 22, so that the energy consumption of the heating assembly 22 is reduced, and the energy storage battery 11 can quickly reach the first preset temperature at a low temperature.
Specifically, the external ambient temperature may be the temperature of the environment surrounding the heating assembly 22, such as the temperature of the environment 1cm to 10cm from the heating assembly. The heating element 22 can be located the periphery wall of energy storage battery 11, the temperature control subassembly 21 can be equipped with the ambient temperature sensor that is used for detecting the outside ambient temperature of heating element 22, when heating element 22 heats energy storage battery 11, the temperature of heating element 22 is higher than the temperature of energy storage battery 11, the temperature rising rate of the outside environment of heating element 22 is fast, the heating rate of energy storage battery 11 is slow, if heating element 22 continuously heats and stops after making the temperature of energy storage battery 11 reach first preset temperature, waste heat of heating element 22 and the waste heat of the outside environment of heating element 22 can be caused, therefore, when energy storage battery 11 supplies power to heating device 2, can adjust the heating beat of heating element 22 according to the temperature of energy storage battery 11 and the outside ambient temperature of heating element 22, make heating element 22 carry out the interval heating to energy storage battery 11, thereby can make full use of the waste heat of heating element 22 and the waste heat of the outside environment of heating element 22 promote the temperature of energy storage battery 11, thereby be favorable to reducing the energy consumption of heating element 22, promote the duration of energy storage battery 11.
Further, the third preset temperature is smaller than the fourth preset temperature, the heating time of the first heating beat is longer than the heating time of the second heating beat, and when the external environment temperature of the heating assembly 22 is lower, the temperature rising speed of the energy storage battery 11 can be increased, so that the energy storage battery 11 can quickly reach the first preset temperature.
In some embodiments of the present invention, the heating time of the first heating cycle is t1, the heating time of the second heating cycle is t2, and t1 and t2 satisfy the following relationship: t1=t2+t0, 1 s.ltoreq.t0.ltoreq.10s, 0S < t2.ltoreq.30s. The third preset temperature is T3, and T3 satisfies the following relation: t3 is less than or equal to-5 ℃ below zero at 10 ℃.
For example, when the third preset temperature is-5 ℃, the fourth preset temperature is the same as the first preset temperature and both are 0 ℃, the heating time of the first heating beat is 15S, the heating time of the second heating beat is 10S, the power supply device for supplying power to the heating device 2 is the energy storage battery 11, and the external environment temperature of the heating component 22 is less than or equal to-5 ℃, the temperature control component 21 controls the heating component 22 to perform interval heating, and the heating time is 15S each time until the temperature of the energy storage battery 11 reaches 0 ℃. When the power supply device for supplying power to the heating device 2 is the energy storage battery 11 and the external environment temperature of the heating component 22 is more than-5 ℃ and less than 0 ℃, the temperature control component 21 controls the heating component 22 to perform interval heating, and the heating time is 10S each time until the temperature of the energy storage battery 11 reaches 0 ℃.
In some embodiments of the present invention, the heating interval time of the first heating cycle is smaller than the heating interval time of the second heating cycle, so as to further increase the temperature rising speed of the energy storage battery 11.
In some embodiments of the present invention, the heating interval time of the first heating cycle is t11, the heating interval time of the second heating cycle is t12, and t11 and t12 satisfy the following relationship: t12=t11+t10, t10.ltoreq.t10.ltoreq.10S, 0S < t11.ltoreq.10S. For example, the heating interval time of the first heating cycle is 3S, the heating interval time of the second heating cycle is 6S, and when the temperature control component 21 controls the heating component 22 to heat the energy storage battery 11 at intervals according to the first heating cycle, the heating component 22 heats the energy storage battery 11 for 15S, and after stopping heating for 3S, the energy storage battery 11 is heated for 15S again, so as to cycle. When the temperature control assembly 21 controls the heating assembly 22 to heat the energy storage battery 11 at intervals according to the second heating beat, the heating assembly 22 heats the energy storage battery 11 for 10S, and heats the energy storage battery 11 again for 10S after stopping heating for 6S, so that the cycle is repeated.
In some embodiments of the present invention, the temperature control component 21 is further configured to obtain a remaining electric quantity of the energy storage battery 11 in real time, and adjust the first heating cycle or the second heating cycle according to the remaining electric quantity of the energy storage battery 11, where the remaining electric quantity is positively correlated with a heating time of the first heating cycle, the remaining electric quantity is negatively correlated with an interval time of the first heating cycle, the remaining electric quantity is positively correlated with a heating time of the second heating cycle, and the remaining electric quantity is negatively correlated with an interval time of the second heating cycle, that is, the higher the remaining electric quantity of the energy storage battery 11, the longer the heating time of the first heating cycle and the second heating cycle, the lower the remaining electric quantity of the energy storage battery 11, and the longer the interval time of the first heating cycle and the second heating cycle, so that the energy storage battery 11 can more fully utilize the waste heat of the heating component 22 and the waste heat of the environment outside the heating component 22 to raise the temperature of the energy storage battery 11, and when the remaining electric quantity of the energy storage battery 11 is lower, the heating component 22 can heat the energy storage battery 11 to a first preset temperature with less energy consumption. In addition, when the remaining power is lower than the preset remaining power, the temperature control component 21 may prohibit the energy storage battery 11 from supplying power to the heating device 2, so as to avoid overdischarge of the energy storage battery 11, and the preset remaining power may be 25% or 10%.
In some embodiments of the present invention, the temperature control component 21 is further configured to obtain the temperature of the energy storage battery 11 in real time, and when the heating component 22 is controlled to heat the energy storage battery 11 to the second preset temperature, control the heating component 22 to continuously heat the energy storage battery 11 until the temperature of the energy storage battery 11 reaches the second preset temperature, thereby, when the non-energy storage battery 11 supplies power to the heating device 2, the heating component 22 can be controlled to continuously heat the energy storage battery 11 regardless of the power consumption of the heating device 2, so that the temperature of the energy storage battery 11 quickly reaches the second preset temperature, thereby being beneficial to improving the charge and discharge performance and the service life of the energy storage battery 11.
In some embodiments of the present invention, the temperature control component 21 is further configured to obtain the temperature of the heating component 22, and when the temperature of the heating component 22 is higher than the fifth preset temperature and/or the temperature of the heating component 22 is not obtained within the first preset time, the temperature control component 21 sends an alarm signal to the control device 3, in other words, when one or both of the conditions that the temperature of the heating component 22 is higher than the fifth preset temperature and the temperature of the heating component 22 is not obtained within the first preset time are met, the temperature control component 21 sends an alarm signal to the control device 3 to improve the safety of the battery heating system 10.
In some embodiments of the invention, the fifth preset temperature is T5, T5 satisfies the relationship 45 ℃ to T5 to 80 ℃, the first preset time is T111, and T111 satisfies the relationship 0S < t111 to 15S. Optionally, the fifth preset temperature is 50 ℃, and the first preset time is 10S. It can be understood that under normal usage conditions of the temperature control assembly 21 and the heating assembly 22, the temperature control assembly 21 controls the temperature of the heating assembly 22 not to exceed the fifth preset temperature, when the temperature of the heating assembly 22 is higher than the fifth preset temperature, it indicates that at least one of the temperature control assembly 21 and the heating assembly 22 is abnormal, the temperature control assembly 21 cannot control the temperature of the heating assembly 22 below the fifth preset temperature, the temperature of the heating assembly 22 exceeds the usage temperature thereof, the heating assembly 22 is burnt, and the energy storage battery 11 is in thermal runaway. Thereby, when the temperature of the heating assembly 22 is higher than the fifth preset temperature, the temperature control assembly 21 sends an alarm signal to the control device 3, so that the control device 3 takes corresponding safety measures, and the risk of burning the heating assembly 22 and thermal runaway of the energy storage battery 11 is avoided.
Meanwhile, the temperature control component 21 obtains the temperature of the heating component 22 at intervals of a first preset time, so that the temperature control component 21 can dynamically adjust the temperature of the heating component 22 according to the heating requirement of the energy storage battery 11. For example, the temperature control assembly 21 may adjust the temperature of the heating assembly 22 by controlling the amount of heat generated by the heating plates in the heating assembly 22. When the temperature of the heating component 22 is not obtained by the heating component 22 within the first preset time, it is indicated that at least one of the temperature control component 21 and the heating component 22 is abnormal, the temperature control component 21 cannot effectively control the temperature of the heating component 22, the heating component 22 is burnt, and the energy storage battery 11 is in thermal runaway. Thus, when the temperature of the heating assembly 22 is not obtained by the heating assembly 22 within the first preset time, the temperature control assembly 21 sends an alarm signal to the control device 3, so that the control device 3 takes corresponding safety measures, and the risk of burning the heating assembly 22 and thermal runaway of the energy storage battery 11 is avoided.
