[0035] Please refer toFigures 1 to 4 As shown, in this embodiment, a battery tray with a temperature acquisition function includes a tray body 1 and a temperature measurement component 2, where: The tray body 1 includes a first bearing surface 10. Along the first direction ( Figure 1 the X direction in []) a number of first receiving portions 100 are arranged at intervals. Each first receiving portion 100 is configured to carry a first type of battery 3 to be tested; The temperature measurement component 2 is arranged on the tray body 1. The temperature measurement component 2 is configured to detect the temperature of the first type of battery 3 in some or all of the first receiving portions 100 in real time when the first type of battery 3 is being tested.

[0036] It can be seen that by arranging a number of first receiving portions 100 on the first bearing surface 10 of the tray body 1, and cooperating with the temperature measurement component 2 to detect the temperature of the first type of battery 3 in some or all of the first receiving portions 100 in real time when the first type of battery 3 is being tested, through the precise monitoring of the battery temperature, the abnormal battery temperature situation can be found in time, and corresponding measures can be taken for treatment, effectively reducing the risk of safety accidents such as battery fire and explosion.

[0037] As an implementation manner, the tray body 1 further includes a second bearing surface 11. The second bearing surface 11 is arranged on the opposite side of the first bearing surface 10. Along the first direction, a number of second receiving portions 110 are arranged at intervals on the second bearing surface 11. Each second receiving portion 110 is configured to carry a second type of battery to be tested. The specifications of the first type of battery 3 and the second type of battery are different; The temperature measurement component 2 is further configured to detect the temperature of the second type of battery in some or all of the second receiving portions 110 in real time when the second type of battery is being tested.

[0038] Specifically, the first type of battery 3 and the second type of battery can be cylindrical batteries or square batteries.

[0039] It can be seen that by adding the second receiving portions 110, and the second receiving portions 110 carry the second type of battery, it can cooperate with the temperature measurement component 2 to detect two types of batteries with different specifications respectively, and has good compatibility.

[0040] As an implementation manner, the temperature measurement component 2 includes a first temperature sensor 20 and a power supply module 21. One first temperature sensor 20 is arranged in each first receiving portion 100. The power supply module 21 is arranged at one end of the tray body 1 in the first direction. The power supply module 21 is configured to supply power to all the first temperature sensors 20 through a wire harness 4.

[0041] It can be seen that by setting the power supply module 21, which is uniformly arranged at one end of the tray body 1, and supplying power to all the first temperature sensors 20 and the second temperature sensors through the wire harness 4, the power supply stability and reliability of the system are ensured.

[0042] Such as Figure 3As shown in the figure, as an implementation manner, a plurality of second accommodating portions 110 and a plurality of first accommodating portions 100 are correspondingly arranged in the first direction. An installation groove is formed through between the first accommodating portion 100 and the corresponding second accommodating portion 110. The first temperature sensor 20 is arranged in the installation groove. The first temperature sensor 20 is configured to detect the temperature of the first type of battery 3 in the first accommodating portion 100 in real time when the first type of battery 3 and / or the second type of battery is being tested, and / or detect the temperature of the second type of battery in the second accommodating portion 110 in real time.

There is no need to separately arrange temperature sensors in the first accommodating portion 100 and the second accommodating portion 110, which simplifies the overall structure and has a low cost.

[0044] As Figure 4 As shown in the figure, as an implementation manner, a plurality of second accommodating portions 110 and a plurality of first accommodating portions 100 are staggered in the first direction. One second temperature sensor is arranged in each second accommodating portion 110. The power supply module 21 is further configured to supply power to all the second temperature sensors through the wire harness 4; the first temperature sensor 20 is configured to detect the temperature of the first type of battery 3 in the first accommodating portion 100 in real time when the first type of battery 3 is being tested; the second temperature sensor is configured to detect the temperature of the second type of battery in the second accommodating portion 110 in real time when the second type of battery is being tested.

[0045] Specifically, both the first temperature sensor 20 and the second temperature sensor are thermistors. Through the thermistors, the temperature change of the battery can be accurately sensed. The first temperature sensor 20 and the second temperature sensor are respectively installed at the bottoms of the first accommodating portion 100 and the second accommodating portion 110 of the tray body 1 to ensure full contact between the temperature sensor and the battery surface, further improving the accuracy of temperature monitoring.

[0046] As an implementation manner, the temperature measuring assembly 2 further includes a data acquisition card. The data acquisition card is configured to receive the analog signals collected by the first temperature sensor 20 and / or the second temperature sensor through the wire harness 4 and convert the received analog signals into digital signals.

[0047] It can be seen that by adding a data acquisition card, and receiving the analog signals collected by the first temperature sensor 20 and / or the second temperature sensor through the wire harness 4 and converting the received analog signals into digital signals, the digital processing and accurate acquisition of temperature data are realized.

[0048] As an implementation manner, a first channel 5 extending in a first direction and passing through all the first receiving portions 100 is provided on the first bearing surface 10, and a second channel 6 extending in the first direction and passing through all the second receiving portions 110 is provided on the second bearing surface 11. The wire harness 4 is disposed in the first channel 5 or the second channel 6.

[0049] The provision of the first channel 5 and the second channel 6 can not only facilitate the taking and placing of the batteries on the tray, but also enable the respective receiving portions on the same bearing surface to communicate with each other, having a certain heat dissipation effect. At the same time, disposing the wire harness 4 in the first channel 5 or the second channel 6 facilitates the routing of the wire harness 4.
