At this time, having a good car emergency power supply will be your lifesaver. But there are many brands and different functions on the market, how to choose? Today, let's analyze how to choose an excellent car emergency starting power supply from the functional point of view!
First of all, we need to understand the working principle and function of the automotive emergency start power supply.
Take the emergency starting power supply of Kedian animal as a case study).
The working principle of the automotive emergency starting power supply mainly involves multiple parts such as AC input, inverter, controller and mutual projection device. When starting the car, the car is first started by a self-throwing and self-relieving mutual projection device, while the system controller charges and manages the alternating current through the charger. When the alternating current is interrupted or overvoltaged, the controller system sends a command to switch to an inverter to power the car, while using the stored power from the battery to supply other products. When the input AC voltage is normal, the controller's system will issue a command to switch the inverter to the shutdown state, and the mutual projection device will start to convert from the inverter to AC power to provide power to other products, and also charge the battery pack.
In addition, the core function of the automotive emergency power supply is the ultra-high rate lithium battery protection, which can instantly output a starting current of several hundred amperes. This kind of power supply is usually equipped with a car charger or a home charger, and the capacity is generally 1 10 of the capacity of the product itself, which only provides supplementary functions for the product, and does not have the function of providing inverter inverter current. Under the control of the controller, the inverter will stop working. The input alternating current will power the car or other charging electronics through a mutual projection device (self-throwing and self-reset). When there is an interruption or overpressure of the alternating current, the controller system sends instructions to the mutual projection device, which switches into the inverter to supply power, and will use the power stored by the battery to power other products. When the input AC voltage is normal, the controller's system will issue a command, and the inverter will switch to the shutdown state. At this time, the mutual projection device starts to convert from the inverter to the AC bypass power supply, and provides AC power for charging other products. It also charges the battery pack.
How to choose the right car emergency starting power supply?
1. Clear needs: your journey of emergency power exploration
Scenario Analysis:Are you a traveler who likes to drive occasionally, or a warrior who often explores remote areas? Different scenarios will determine the function and capacity of the emergency power supply you need, compared to the small partners who often go out, the frequency of the car emergency starting power supply for daily life is not very high, but once it is used in an emergency, this time may be able to leave you a lot of time and money (a few hundred dollars less than a few hundred dollars at a time).

Second, the brand and type: the quality of the contest
Battle of Reputation:Choose a power supply brand with a long warranty period and good after-sales, based on quality and speaking with reputation.
Battery Choice:Should you choose a traditional lead-acid battery, or a lightweight lithium-ion battery? According to your preferences and usage habits to make a wise choice, the main difference between the two power supplies is the difference in the use of the scene environment and service life.
3. Core parameters: the mystery of the source of initiation
Capacity Wisdom:The capacity is directly related to the number of starts and power supply time. Choose the right capacity, so that your emergency power supply does not drop the chain at a critical moment.
Concerto of Voltage and Current:Make sure that the voltage and current of the emergency power supply are perfectly matched to your car, so that you can start without worry.
Fourth, additional functions: beyond the infinite possibilities of startup
Practical Light:In addition to the activation function, additional functions such as LED lighting, SOS distress signal, mobile phone charging, tire inflation and other additional functions will light up the light of hope for you in an emergency and cope with various driving emergencies.
Smart Protection:Some high-end emergency power supplies also have power display, self-test and other functions, and the suitable environment is suitable for low-temperature freeze-resistant, high-temperature and heat-resistant products, so that technology can escort your safety.
5. Service and after-sales: protect your driving safety
Warranty Shield:Carefully selected products also need to be supported by a comprehensive warranty policy. Check the warranty period of the product, and whether there is a charge during the warranty period, to add a layer of protection to your rights.
After-sales strength:Understand the brand's after-sales service system, whether it provides maintenance, replacement and other services. Choose a brand with strong after-sales support to keep your emergency power supply in tip-top condition at all times.
Finally, don't forget to refer to the evaluations and suggestions of other car owners, the products broadcast between car owners will be relatively good in terms of quality and after-sales, and you can choose a high-quality car emergency power supply that is really suitable for you, escorting safe driving! From novice to expert, are you ready? Let's embark on this gorgeous journey of choosing a car emergency power supply together! This is the emergency starting power supply for Kedian beast automobiles, focusing on the manufacture of automotive safety starting power supply
