Introduction

The failure of a vehicle’s battery is an emergency situation that every car owner may face. In such cases, car jump starters and portable external battery chargers become essential tools. This blog post will delve into the working principles and technical aspects of these tools, as well as how to handle emergency situations when a vehicle’s battery fails.

  1. Working Principles and Technical Analysis of Car Jump Starters

A car jump starter is a multifunctional device that not only helps start a vehicle but also serves as a portable external battery charger. Its working principles are based on the following aspects:

Battery Capacity and Output Power

Car jump starters are typically equipped with high-capacity lithium-ion batteries, such as 12000 mAh. These high-capacity batteries provide sufficient power to start a vehicle. Additionally, car jump starters have high output power, usually ranging from 200 to 600 amps, to meet the requirements of different vehicles.

Protection Circuits

Car jump starters are built with various protection circuits to ensure safe usage. These circuits include overcurrent protection, overvoltage protection, short-circuit protection, and more. They prevent battery over-discharge or damage while safeguarding the vehicle’s electronic systems from harm.

Charging Functionality

In addition to jump-starting cars, car jump starters can also be used as external battery chargers. They are typically equipped with USB ports to charge devices such as smartphones and tablets.

  1. Working Principles and Technical Analysis of Portable External Battery Chargers

A portable external battery charger is a device used to charge a vehicle’s battery. Its working principles are based on the following aspects:

Charging Method

Portable external battery chargers usually employ constant current charging, which provides a steady current to charge the battery. This charging method ensures high charging efficiency without causing any harm to the battery.

Charging Voltage and Current

The charging voltage and current of external battery chargers need to be adjusted according to the requirements of the vehicle’s battery. Generally, the charging voltage for vehicle batteries is 12 volts, with a charging current ranging from 2 to 10 amps.

Charging Protection

Portable external battery chargers are typically equipped with various protection features to ensure safe charging. These include overcharging protection, overcurrent protection, short circuit protection, and more. These protective measures prevent battery overcharging or damage.

  1. Dealing with Emergency Situations of Battery Failure

When faced with a vehicle battery failure, car jump starters and portable external battery chargers can help you handle the emergency. Here are some measures to consider:

Using a Car Jump Starter

Connect the positive and negative terminals of the car jump starter correctly to the corresponding terminals of the vehicle’s battery, then start the vehicle. The high output power of the jump starter will provide enough energy to start the vehicle.

Using a Portable External Battery Charger

Connect the portable external battery charger correctly to the vehicle’s battery and follow the charger’s instructions for charging. The charger will employ constant current charging to restore the battery’s energy.

Seeking Professional Assistance

If you are unfamiliar with the operation or unable to resolve the issue, it is advisable to seek professional help. Contact a roadside assistance service or an automotive repair centre, as they can provide expert assistance and support.

Conclusion

Car jump starters and portable external battery chargers are essential tools for dealing with emergency situations caused by vehicle battery failure. Understanding their working principles, technical aspects, and proper usage methods can help you quickly resolve problems during emergencies. Remember, safety always comes first. If you are unsure about the operation or encounter difficulties, seek professional assistance.
