The temperature sensor monitors the temperature data of the coolant at the inlet connector 111 and the outlet connector 112 of the liquid cooling equipment. The temperature sensor transmits the monitored temperature data to the management system via a bus (CAN / Ethernet) and adjusts the temperature of the coolant in the liquid cooling equipment after human-machine interaction.
[0070] Among them, the test equipment 300 is used to collect parameters such as voltage, current, temperature, and internal resistance of the module under test 200 in real time based on the charging and discharging strategy (such as NEDC and WLTC standards) and the operating conditions simulation, and dynamically adjust the current / voltage threshold.
[0071] Please see Figure 12 and Figure 13 The liquid cooling plates 1 of two adjacent module test fixtures 100 are interconnected. The liquid cooling plates 1 of the two adjacent module test fixtures 100 are a first liquid cooling plate 101 and a second liquid cooling plate 102, respectively. The first liquid cooling plate 101 is provided with a first liquid cooling connector group 1011, which includes a first liquid cooling inlet connector 10111 and a first liquid cooling outlet connector 10112. The second liquid cooling plate 102 is provided with a second liquid cooling connector group 1021, which includes a second liquid cooling inlet connector 10211 and a second liquid cooling outlet connector 10212. The first liquid cooling outlet connector 10112 is connected to the second liquid cooling inlet connector 10211, and the first liquid cooling inlet connector 10111 is connected to the second liquid cooling outlet connector 10212. The first liquid cooling plate 101 and the second liquid cooling plate 102 are connected via the first liquid cooling connector group 1011 and the second liquid cooling connector group 1021. This enables a more uniform heat distribution and more efficient heat conduction, helping the two modules 200 under test maintain a stable temperature during testing, avoiding localized overheating, and improving overall thermal management efficiency. The coolant can circulate over a larger surface area, thus improving cooling efficiency. It also reduces the complexity of the cooling system, decreasing the number of pipes and connectors. This not only simplifies system design but may also reduce maintenance costs and failure risks. Furthermore, it optimizes the coolant flow path; connecting the liquid cooling plates 1 reduces coolant consumption and pump energy consumption, resulting in a more energy-efficient cooling solution.
