Modern lithium battery systems rely heavily on communication interfaces to monitor status, ensure safety, and exchange data with host devices. A Battery Management System (BMS) acts as the “brain” of a lithium battery pack, and communication protocols are the language it uses to talk with chargers, controllers, computers, and user interfaces. This article explains […]
Below is a clear, BMS-focused explanation of how many data cables (signal wires) each communication protocol requires, plus what’s usually added in real battery systems. 1. RS232 Data cables required 2–3 signal wires Signal Purpose TX Transmit data RX Receive data GND Signal ground (required) Typical wiring Minimum:TX + RX + GND → 3 wires […]
Lithium-ion batteries have become the standard power source for everything from consumer electronics to electric vehicles, thanks to their high energy density, long cycle life, and relatively low self-discharge. However, their unique electrochemical characteristics make proper charging crucial. One of the most important rules in lithium-ion battery charging is that the charging current should not […]
Lithium-ion batteries have become ubiquitous in modern electronics due to their high energy density and long cycle life. However, their unique chemical characteristics make proper charging crucial for both safety and longevity. Among all charging methods, the CC/CV (Constant Current / Constant Voltage) method is universally recommended. 1. Chemical Characteristics of Lithium Batteries Lithium batteries store […]
In today’s battery technology landscape, lithium-ion batteries (NMC/NCA) and lithium iron phosphate (LiFePO4 or LFP) batteries are the two dominant chemistries. Together, they power the global transition to clean energy—supporting applications ranging from electric vehicles and consumer electronics to home energy storage and telecom backup systems. Although both belong to the lithium family, their chemical structures lead to […]
In the world of cylindrical lithium-ion batteries, 18650 and 26650 are two of the most well-known and widely used formats. They have been on the market for many years and are still essential in many industries today. The numbers in their names act like an “ID card”: The first two digits indicate the diameter (in millimeters) The next […]
If you open a lithium battery protection board and take a closer look, two components immediately stand out: the protection IC and one or more MOSFETs. They are always there, whether it is a simple single-cell protection board or a high-current battery pack used in industrial equipment. People often ask which one is […]
When people talk about batteries, the conversation often starts with numbers — energy density, cycle life, cost per watt-hour. In practice, however, battery selection is rarely that simple. Different battery chemistries behave very differently once they are placed into real products, operating in real environments, with real users. What looks good on a datasheet does […]
A dual-circuit BMS (Battery Management System) refers to a battery management system that utilizes two separate, independent circuits to manage and protect a battery pack. These circuits are typically designed to handle battery monitoring, protection, charging, and discharging etc., with dual circuit enhance the overall performance, safety, and reliability of the system. Key Characteristics of a […]
Lithium Polymer (LiPo) batteries are widely used because they are light and powerful. However, many people ask: Why can’t a LiPo battery be made exactly the same size as the battery case? The answer is safety. Why LiPo Batteries Cannot Fit Tightly in the Case LiPo batteries need extra space to “breathe.” During […]
