1. When the equipment suddenly fails during the test operation, a corresponding fault display prompt appears on the control instrument and there is a voice alarm. The operator can quickly check which type of fault belongs to in the troubleshooting chapter of the operation of the equipment, and then the professional can quickly eliminate the fault to ensure the normal operation of the test. Other environmental test equipment will have other phenomena in use, it must be specific phenomena, specific analysis and exclusion. 　 2. If the low temperature fails to reach the target of the test, then you must observe the change of temperature. It is the temperature drop is very slow, or the temperature has a tendency to rebound after the temperature reaches a certain value. The former must check whether it will be before the low temperature test. After drying in the studio, the test chamber is kept dry and the test sample is placed in the work chamber. The test sample is placed in the work chamber. The test sample in the work chamber is placed too much, so that the air in the work chamber cannot be fully circulated. After eliminating the above reasons, It is necessary to consider whether it is a fault in the refrigeration system. In this case, it is necessary to ask a manufacturer's professional to perform the repair. The latter phenomenon is caused by the poor use environment of the equipment. The ambient temperature of the equipment and the location of the equipment ( the distance between the cabinet and the wall ) must meet the requirements (as specified in the equipment operation instructions ) . 　 3. In the damp heat test, the actual humidity will be reached Or the actual humidity is very different from the target humidity, and the value is much lower. The former phenomenon may be caused by dry gauze on the wet-bulb sensor. Check the water tank of the wet-bulb sensor for water shortage. The water level in the water tank is determined by If the water level controller is automatically controlled, check whether the water level controller water supply system is normal and whether the water level controller is working properly. Another possibility is that the wet ball gauze may cause the gauze to become hard due to the long use time or the purity of the water supply, so that the gauze cannot absorb the moisture and dry, and the above phenomenon can be eliminated only by replacing or cleaning the gauze. The latter phenomenon is mainly because the humidification system is not working. Check the water supply system of the humidification system. Check whether there is a certain amount of water in the water supply system. Control whether the water level of the humidifying boiler water level is normal and whether the water level in the humidifying boiler is normal. If all of the above is normal, then check the electrical control system, which requires professional maintenance personnel to perform the repair. 　 4. In the high temperature test, if the temperature change does not reach the test temperature value, the electrical system can be checked and the faults can be eliminated one by one. If the temperature rises very slowly, it is necessary to look at the air circulation system and see if the adjustment baffle of the air circulation is normally open. Conversely, check whether the motor operation of the air circulation is normal. If the temperature overshoots badly, then you need to set the PID setting parameters. If the temperature rises directly, over-temperature protection, then the controller fails and the control instrument must be replaced. 　　 The environmental testing equipment should also be regularly maintained. The condenser of the refrigeration system should be regularly cleaned. For the moving parts, lubrication should be performed according to the instructions, and the electrical control system should be regularly maintained and inspected. These tasks are indispensable. At present, there are mainly two types of pure electric vehicles and hybrid electric vehicles in the market. Pure electric vehicles are completely powered by electricity and do not generate any exhaust emissions, thus having the lowest pollution. Hybrid electric vehicles can be driven by both fuel and electricity, and the assistance of electricity can reduce fuel consumption and exhaust emissions. Compared to the two, pure electric vehicles are more environmentally friendly and can better adapt to use in specific environments.

With the advancement of technology and people's pursuit of environmental protection and low-carbon modes of transportation, electric vehicles will become the mainstream means of transportation in the future. More and more car manufacturers are beginning to invest in the research and production of electric vehicles, continuously improving battery technology and range, and improving the performance and user experience of electric vehicles.
