Lithium batteries can be used as a starting power source for vehicles, but attention should be paid to their output power limitations and safety issues.

Advantage

Lithium batteries are widely used in mobile electronic devices due to their lightweight, high energy density, and long lifespan. Compared to traditional lead-acid batteries, lithium batteries have higher energy density and can provide longer usage time. In addition, lithium batteries are smaller in size, lighter in weight, and easier to carry and install.

Applicability analysis

In practical car starting applications, lithium batteries can be used as auxiliary power sources, such as power supplies for car purifiers or audio systems. But if lithium batteries are to be used as a starting power source for vehicles, the following conditions must be met: firstly, lithium batteries need to provide sufficient current to provide high-energy power in a short period of time to start the engine. Secondly, lithium batteries need to have a constant output voltage and output power in order to maintain sufficient inter period starting energy for a long time. In addition, due to the safety issues of lithium batteries, correct installation and protection measures must be taken to strictly limit the occurrence of abnormal situations such as overcharging, overdischarging, and battery short circuits.
