With the arrival of summer, various parts of the country have also entered a rainy season. At this time, various regions in the south and north may be affected by rainwater. As users of electric vehicles, waterproofing should be the key to facing this situation. So, let\'s talk about which parts of electric vehicles are most afraid of water, and how can we prevent water damage? So what kind of IP waterproof rating should be achieved? How to detect electric vehicle accessoriesIP waterproof ratingWhat about it?

Firstly, we should clarify which parts of electric vehicles need to pay attention to waterproofing. What is the required waterproof level for IP?

From the perspective of the overall design and key points of electric vehicles, the four major components of electric vehicles, namely the battery, motor, controller, and lighting fixtures, are constantly following the electric vehicle. These four components are also the main reasons for electric vehicles being short circuited due to water ingress and unable to ride.

1、 Motor water ingress

Nowadays, most electric vehicle motors on the market are rear mounted, and the motor is the lowest main component from the ground on which to ride, making it the most susceptible to water ingress. Once water ingress occurs, it becomes the main part that causes a short circuit. During cycling, if it involves deep water, it is easy for rainwater to enter the motor shaft, causing a short circuit in the motor circuit and resulting in the problem of being unable to ride. Moreover, the motor is the soul and core component of the electric locomotive, and its price is relatively expensive. Therefore, the IP waterproof level must be high enough to withstand the impact and immersion of water in all aspects. So only waterproof rating of IP67 or above is required. Because the IP67 waterproof rating means completely preventing dust from entering and withstanding strong water jets aimed at the motor from every direction without causing damage. When immersed in water for a short period of time under standard pressure, there should be no water that can cause harmful effects. So its detection can be done using the IP waterproof detection equipment from HiSilicon

2、 Short circuit caused by water ingress into the controller

The controller is usually arranged under the rear seat, which has relatively good airtightness and is not directly exposed to the air. However, there are also some simple electric vehicle controllers that are transferred under the vehicle beam at a lower position, which is prone to water ingress and can also cause short circuits when submerged in water. So the waterproof requirement for the controller should be IP66, which is quite reasonable. IP66 can withstand the spray of various water flows without affecting the use of the controller and the adverse factors caused by water, because the possibility of the controller being soaked in water is generally small, unless the electric vehicle is a top-level configuration and requires waterproof rating of IP67 or above. The IP66 and IP67 waterproof testing of the controller of the electric vehicle can also be carried out using the air tightness testing equipment of Hai Rui Si Automatic Technology, which can be applied to different working conditions and IP waterproof level testing

3、 Rainwater short circuit of battery

The battery is the power source of electric vehicles. If the battery is flooded, it can easily cause a short circuit, resulting in power failure and even the risk of electric shock. So, the detection of the IP waterproof level of the battery is also indispensable. Therefore, if you want electric vehicles to be waterproof, you need to achieve waterproofing for the three major components of the motor, controller, and battery. The waterproof testing of batteries can also be carried out using the air tightness leak detection equipment of Hairui Si Automatic Technology, because if the country is promoting new energy electric vehicles, the batteries of electric vehicles are definitely more complex than those of electric vehicles. Our company can also test the batteries of electric vehicles, so of course, electric vehicles are no problem

To further increase the sales of electric vehicles, the IP waterproof rating of their lighting fixtures must also be essential. Our company can also perform IP waterproof testing on the same lighting fixtures, such as IP65 waterproof testing for LED lights, IP65 waterproof testing for street lamps, IP66 waterproof testing for solar lighting fixtures, IP67 waterproof testing for underwater lighting fixtures, etc.

Looking at many global airtightness testing equipment companies, many brands of airtightness testing equipment have conducted extensive research and experimental work on waterproof testing, sealing testing, and IP level testing, and have achieved good results. In places where waterproof testing, sealing testing, IP level testing, and leakage testing are conducted, it is common to see the presence of Haier\'s air tightness leak detection equipment shuttling around, which to some extent indicates that the detection ability of Shenzhen Haier\'s air tightness leak detection equipment is extraordinary.
