How to start the car with emergency starting power
With the increase in the popularity of automobiles, there are more and more cases where the vehicle battery is exhausted and cannot be started. Emergency starting power supplies have received widespread attention in recent years as a portable solution. This article will introduce in detail how to use emergency starting power to start a vehicle, and attach relevant data on recent hot topics and hot content.
1. Working principle of emergency starting power supply
The emergency starting power supply is essentially a large-capacity lithium battery that helps the vehicle start by providing instantaneous high current. Its working principle is to replace traditional batteries and provide temporary power support when the battery power is low.
| part | Function |
|---|---|
| Lithium battery pack | Store electrical energy |
| Intelligent protection circuit | Prevent overcharge and overdischarge |
| LED lighting | Emergency lighting function |
| USB interface | Charge electronic devices |
2. Usage steps
1.Check vehicle condition: Confirmed that it is a battery problem that causes the inability to start, rather than other mechanical failures.
2.Preparation tools: Make sure the emergency power supply has sufficient power (it is recommended to maintain more than 80% power).
| vehicle type | Minimum power required |
|---|---|
| small car | 200-300A |
| Medium SUV | 400-500A |
| Large off-road vehicle | 600A or more |
3.Connect power: - The red clip is connected to the positive terminal of the battery (+) - The black clip is connected to the metal part of the car body (ground)
4.start vehicle: - Wait 30 seconds for the power supply to recognize the voltage - Try to start, no more than 5 seconds each time - Try again after an interval of 1 minute
5.Disconnect: - Disconnect the black clip first - then the red clip
3. Precautions
1.Safety first: Make sure the clip does not contact other parts of the metal body to avoid short circuit.
2.ambient temperature: Extremely cold weather will affect the performance of the power supply, so it is recommended to preheat it in advance.
| temperature range | Performance impact |
|---|---|
| >0°C | normal use |
| -10°C～0°C | Efficiency reduced by 20% |
| ＜-10°C | Not recommended |
3.Regular inspection: Charge the emergency power supply every 3 months to maintain optimal condition.
