Требуют ли моторные испытания новых энергетических транспортных средств установки охладителя или нагревателя?

Для испытания двигателя нового энергетического транспортного средства требуется как охладитель, так и нагреватель, поскольку испытания двигателя охватывают широкий диапазон температурных условий для обеспечения производительности и стабильности работы двигателя в различных условиях эксплуатации. Охладитель: В ...

Chiller: In high load operation of the motor or high ambient temperature, the motor and its controller will generate a large amount of heat. The chiller absorbs and takes away this heat by circulating coolant, helping to maintain the motor temperature within a controllable range and avoiding performance degradation or damage caused by overheating. The chiller ensures temperature management during the testing process, especially during full load testing, efficiency testing, or durability testing, to simulate the cooling needs of the motor in actual use.

Heater: In low-temperature environments or when cold start testing is required, the motor may face difficulties in starting or performance limitations. At this point, the heater becomes particularly important as it can quickly heat the coolant or test the environment, simulate the working state in a low-temperature environment, test the low-temperature starting performance, low-temperature warming performance of the motor, and work efficiency in cold climates.

Therefore, new energy vehicle motor testing is usually equipped with a cold and hot integrated machine or separately equipped with a chiller and heater to achieve comprehensive temperature control of the motor, meet the testing requirements in various ranges from low temperature to high temperature, and ensure that the motor can operate stably and reliably throughout the entire temperature range. This can not only verify the heat dissipation ability of the motor under high temperature conditions, but also test its starting and operating performance under low temperature conditions.
