Caution in installing on board electrical appliances

Some people like to build their car into a "mobile home": a car TV, a car refrigerator, a car vacuum cleaner, an air purifier, etc. are installed in the car all at once, and even mobile phones and laptops are charged in the car However, the quality of on-board products is uneven, or improper installation and use bring hidden dangers to vehicle safety

It is not recommended for car owners to install by themselves


First of all, the additional electrical equipment must be dedicated to the vehicle, such as DVD and other audio-visual appliances must be dedicated to the vehicle. As various technical parameters have been considered by the manufacturer, the selection of special on-board electrical equipment can guarantee the rated voltage, current, anti-interference, stability and other aspects. In addition to the above technical details, it is necessary to invite professionals from professional automobile service stations to install wiring, because modern automobile circuit design and layout tend to be electronic, and the requirements for installing electrical appliances are very standardized. When the car is running, the environment is very bad. If it is roughly installed, it will be easily damaged or fall off in the bumpy, high temperature and humid environment due to the weak connection and poor sealing, resulting in short circuit, damage to electrical equipment and fire.

Don't be greedy for bargains

Now, there is a lot of information about small car appliances on the shopping website - the low price of these products only needs dozens of yuan, and the high price is thousands of yuan. However, little attention has been paid to the risks behind these appliances. Car owner Mr. Wang: "I bought several low-cost car chargers and car refrigerators on the Internet. The car charger was burnt, and the fuse of the cigarette lighter was burnt out." After carefully examining the packaging boxes and online messages, he found that many of these on-board appliances did not have a manufacturer or address. When they were delivered by express, there was only one packaging box. Some products did not even have instructions, and they could not be compared with the electronic products in automobile 4S stores.

Careful use of vehicle inverter

In order to charge mobile phones and laptops on the car, some car owners will install an on-board inverter on their car. It is understood that the on-board inverter is a device that can convert 12V (diesel vehicle is 24 V) DC into 220 V AC. with it, you can use the electrical appliances that are usually used at home in the car, and charge the battery at the same time.

"When you buy on-board inverters, you must choose a good brand, because poor quality on-board inverters are easy to get hot and hot after working for a period of time. In summer, when the temperature in the car is high, explosion may occur." Industry experts have warned that the original 12V voltage on the car, even if there is a problem, is not very harmful to the car owner, but if it becomes 220V voltage, once the inverter has a problem, the consequences may be very serious, "in addition, when using the on-board inverter, you should pay attention to clean the dirt at the plug in time, so as not to cause poor contact or abnormal overheating of the converter.".
It is not suitable to use multiple vehicle electrical appliances at the same time


According to industry insiders, there are mainly two kinds of on-board electrical appliances, one is to connect the cigarette lighter, the other is to install the wiring by itself. No matter which installation method, improper use will bring safety hazards. Vehicle electrical appliances should not be used too much at the same time. In addition, it is not recommended to use some vehicle electrical appliances such as kettle, rice cooker, etc. The spare wiring points and circuit load of the original circuit in the car are limited. If the car owner increases a large number of on-board electrical appliances, it will lead to short circuit of wires and damage of electrical equipment.
