Battery Manufactory

As the most mainstream energy storage device at present, lithium batteries are widely used in various electronic devices such as mobile phones, laptops, mobile power supplies, electric vehicles, etc. However, lithium batteries of different devices show obvious differences when charging. These differences are not only due to the characteristics of the battery itself, but also closely related to the design logic of the charger. This article will analyze the core differences between different devices charging lithium batteries from the dimensions of charging method, protocol support, and safety protection. I. Charging mode: constant current and constant voltage are the basis, and the details are different. The standard charging process of lithium batteries is divided into two stages: constant current charging and constant voltage charging: the initial stage is fast charging with constant current. When the voltage rises to the rated value (such as 4.2V or 4.35V, depending o...
