Referring to fig. 1 of the drawings, a temperature regulation control system of a battery pack according to an embodiment of the present utility model includes a battery pack 100, a first temperature acquisition unit 200, a second temperature acquisition unit 300, a controller 400, and a temperature regulator 500, wherein:
the battery pack 100 is composed of a plurality of groups of batteries, is installed on the photovoltaic cleaning equipment and is used for supplying power to the photovoltaic cleaning equipment; the first temperature acquisition unit 200 is arranged on the outer surface of the battery inside the battery pack and is used for acquiring the internal temperature of the battery pack; a second temperature acquisition unit 300, disposed on the outer surface of the battery outside the battery pack, for acquiring the temperature of the periphery of the battery pack; the controller 400 is connected with the first temperature acquisition unit and the second temperature acquisition unit respectively and is used for sending a temperature control signal according to the temperature difference between the internal temperature of the battery pack and the temperature of the periphery of the battery pack; the temperature regulator 500 is disposed inside the battery pack and connected to the controller, and is used for heating or cooling the battery pack according to the temperature control signal.
Specifically, photovoltaic module is cleaned by adopting photovoltaic cleaning equipment in a photovoltaic power station, a battery pack 100 is installed in the photovoltaic cleaning equipment, power is supplied to the photovoltaic cleaning equipment, and the battery pack 100 comprises a plurality of batteries. In the actual charge and discharge process, the battery can generate heat, so that the temperature difference between the battery outside the battery pack and the battery inside the battery pack is overlarge, the temperature of the battery inside the battery pack is high, the temperature of the battery outside the battery pack is low, and the charge and discharge efficiency of the whole battery pack is unbalanced. Therefore, a first temperature acquisition unit 200 is provided inside the battery pack 100, a second temperature acquisition unit 200 is provided around the battery pack 100, and the battery temperatures inside and around the battery pack 100 are acquired in real time and transmitted to the controller 400; the controller 400 transmits a temperature control signal to the temperature regulator 500 according to a temperature difference between the internal temperature and the circumferential side temperature of the battery pack.

The temperature regulator 500 is connected to the controller 300, and, upon receiving a temperature control signal transmitted from the controller 400, increases or decreases the temperature of the periphery of the battery pack 100 according to the control signal.
Because the battery pack can generate heat during charge and discharge, the temperature of the battery inside is higher than that of the battery outside generally, and a temperature difference is generated inside the battery pack, so that the charge and discharge efficiency of the battery pack is influenced in the continuous charge and discharge process, and the normal operation of the photovoltaic cleaning equipment is further influenced. The temperatures of the inside and the periphery of the battery pack are collected through the first temperature collection unit 200 and the second temperature collection unit 300, so that when the temperature difference of the battery pack is abnormal, the temperature difference of the battery pack is timely regulated and controlled through the controller 400 and the temperature regulator 500, the battery pack 100 is enabled to work at a proper temperature, the performance of the battery pack is improved, and the working efficiency of the photovoltaic cleaning equipment is improved; and the temperature regulator 500 is provided inside the battery pack, enabling precise regulation.
Based on the foregoing embodiments, in the present embodiment, a battery pack includes at least one center battery and a plurality of unit batteries disposed around the center battery; the battery pack also comprises a plurality of clapboards, and a baffle is arranged between every two batteries; the first temperature acquisition unit comprises a plurality of temperature sensors, and each temperature sensor is arranged on the surface of a central battery in the battery pack and is used for acquiring the current battery temperature of the central battery in real time; the temperature regulator comprises heating wires, and the heating wires are wound on the outer surface of each single battery.
Specifically, for example, the battery pack is composed of seven lithium iron phosphate batteries, and generally the most middle 1-2 batteries are provided as the center battery, and the rest of the unit batteries are provided around the center battery. Preferably, fig. 2 shows a structure diagram when a plurality of single batteries are placed, the heating wire 1 is uniformly wound on the surface of each single battery 3, a partition board 4 is arranged between two adjacent batteries, and the partition board 4 enables the adjacent batteries to be close to each other as much as possible and separates the positive electrode from the negative electrode of the adjacent batteries. A temperature sensor 2 is arranged at the top of each single battery 3, the temperature sensor 2 is connected with a controller (not shown in the figure), and the acquired current battery temperature of the corresponding single battery 3 is sent to the controller; the controller combines the received current temperature of the central battery sent by the first temperature acquisition unit, sends a temperature control signal to the heating wire 1 according to the temperature difference between the temperature of the single battery and the temperature of the central battery, and the heating wire heats up or stops heating according to different temperature control signals.
In this embodiment, because the battery pack of the photovoltaic cleaning device is generally smaller in volume, the heating wire is used as a temperature regulator, so that the charging and discharging temperature difference of the battery pack can be accurately controlled, the battery pack is not excessively large in volume and occupies extra space, and the heating wire has the advantages of low cost and easiness in acquisition.
On the basis of the previous embodiment, the temperature regulation control system of the battery pack provided by the utility model further comprises a switch which is respectively connected with the controller and the temperature regulator; when the switch is in a conducting state, the controller sends a temperature control signal to the temperature regulator; when the switch is in the off state, the controller stops sending the temperature control signal to the temperature regulator. The embodiment further sets a switch, and drives the heating wire (temperature regulator) to work through the controller by utilizing different working states of the switch: when the temperature difference of the battery is outside a preset temperature range, the heating wire is heated according to the control signal; and when the temperature difference of the battery is within the preset temperature, the controller stops outputting a control signal to the heating wire, so that the temperature of the heating wire is reduced. The switch can preferably adopt a MOS tube driving circuit.
In one embodiment, the thermostat 400 includes: the power supply control chip is connected with the controller, receives the temperature control signal and outputs positive electricity/negative electricity; and the semiconductor refrigerators are connected with the power supply control chip, one semiconductor refrigerator is arranged between every two adjacent single batteries, and the semiconductor refrigerator is heated or cooled after receiving forward/reverse electricity.
Specifically, the semiconductor refrigerator (TEC, thermoElectricCooler) is a sheet-like device made of semiconductor materials by utilizing the Peltier effect, can realize heating and refrigeration by changing the current direction, and is a temperature control component with higher temperature control precision at present. Due to the TEC material characteristics, when different voltage signals are received, different working states (refrigeration/heating) can be switched, and when forward current flows through the TEC, the TEC works in a heating mode; when negative current flows through the TEC, the TEC operates in a cooling mode. TEC temperature adjusting units (for executing heating or cooling treatment according to the input forward power or reverse power) are added between adjacent single batteries of the battery pack, and the temperature of each single battery is adjusted by matching with a power supply control chip (for controlling the output of the forward power or the reverse power). The output of the power control chip is determined by a temperature control signal sent by the controller.
In one embodiment of the present utility model, as shown in fig. 3, a temperature regulation control system of a battery pack includes: the battery pack consists of a plurality of groups of batteries, is arranged on the photovoltaic cleaning equipment and is used for supplying power to the photovoltaic cleaning equipment; the first temperature acquisition unit is arranged on the outer surface of the battery inside battery and is used for acquiring the internal temperature of the battery inside battery; and the second temperature acquisition unit is arranged on the outer surface of the battery outside the battery pack and used for acquiring the temperature of the periphery of the battery pack.
Specifically, a power supply battery pack is installed in the photovoltaic cleaning robot and consists of a plurality of batteries, and preferably a lithium iron phosphate battery is adopted. In the process of charging and discharging each battery unit, the temperature of the battery unit outside the battery pack is low, the temperature of the battery unit close to the inside is high, the battery temperature greatly affects the discharging performance of the battery, and each battery temperature imbalance can lead to unbalanced charging and discharging of each battery unit of the whole battery pack, so that the performance of the battery pack is affected. Therefore, a temperature acquisition unit is arranged in the battery pack to acquire the temperature difference between the battery in the battery pack and the battery on the periphery, and the temperature of each battery is monitored in real time.
And the ring temperature sensor is connected with the controller and used for collecting the current environmental temperature of the working environment where the battery pack is located in real time. The working environment of the photovoltaic cleaning equipment is generally in the field, the temperature change is large, and supercooling or overheating can influence the capacity of a power supply battery of the photovoltaic cleaning equipment, so that the long-term use of the battery is not facilitated. Therefore, when the ambient temperature changes, the battery temperature also needs to be adjusted. The temperature rising/reducing condition of the surrounding environment can be known through the ring temperature sensor, so that the battery temperature can be regulated in advance, and the service life of the battery pack can be prolonged.
The controller is respectively connected with the first temperature acquisition unit, the second temperature acquisition unit and the ring temperature sensor and is used for sending a temperature control signal according to the temperature difference between the internal temperature and the peripheral side temperature of the battery pack; and the system is also used for sending a temperature control signal according to the temperature difference between the current environment temperature and the early warning air temperature, and particularly, the early warning air temperature is usually at extreme temperatures, such as the extreme high temperature or the extreme low temperature which can be operated by the battery pack.
Specifically, if the temperature difference of the battery pack is outside the preset temperature range, the controller outputs a temperature rise control signal to the temperature regulator, and otherwise, outputs a temperature reduction control signal. When the temperature difference is outside a first preset temperature range, the controller outputs a temperature rise control signal; and when the air temperature difference is outside a second preset air temperature range, the controller outputs a cooling control signal. Based on the temperature control signal sent by the controller, the battery temperature inside the battery pack and the battery temperature at the periphery are balanced. The controller may employ a common variety of PID controllers, such as outputting PWM temperature control signals via discrete PID controllers, and the like.
And the temperature regulator is arranged inside the battery pack, connected with the controller and used for heating or cooling the temperature of the periphery of the battery according to the temperature control signal. Specifically, for example, each battery (except for one or two central batteries in the middle of the battery pack) is wound with a group of heating wires, an MOS tube is arranged between the heating wires and the controller, the MOS tube receives a temperature control signal to control the heating wires to raise/lower the temperature, and the heating wires are used as temperature regulators, so that the battery pack has the advantages of simplicity and convenience in operation and easiness in implementation.
The working environment of the photovoltaic cleaning equipment (such as a photovoltaic cleaning robot) is generally in the field, the environmental temperature is greatly changed, and the capacity of the battery pack is influenced by supercooling or overheating, so that the long-term use of the battery pack is not facilitated. Therefore, when the ambient temperature changes, it is also necessary to adjust the temperature of each battery in the battery pack. According to the embodiment, the ring temperature sensor is additionally arranged on the basis of the embodiment, so that the temperature rising/reducing condition can be known, the battery temperature can be conveniently adjusted in advance, certain flexibility is realized when the battery temperature is controlled, the battery performance is improved, and the service life of the battery is prolonged.
An embodiment of the utility model provides a photovoltaic cleaning device, which comprises the temperature regulation control system of any battery pack. Specifically, the photovoltaic module is a core part in the solar power generation system, and the photovoltaic module is generally placed in the open air, and due to weather changes such as sand dust, strong wind and the like, and natural reasons such as bird droppings pollution and the like, covers such as stains, sand dust and the like which are difficult to remove are formed on the photovoltaic module, so that the power generation rate of the photovoltaic module is seriously affected. Therefore, a photovoltaic cleaning apparatus is required for cleaning a photovoltaic module in a photovoltaic power generation system to improve the working efficiency of the photovoltaic power generation system. The photovoltaic cleaning equipment is also provided with a battery pack which is used as a power supply source of the photovoltaic cleaning equipment; preferably, the battery pack is formed by adopting the lithium iron phosphate battery, and has better safety performance and high-temperature performance and longer service life.
