Why Did My E-Bike “Suddenly Die”? Understanding BMS Protection.

Is your e-scooter or e-tricycle losing several battery bars the moment you accelerate or climb a hill? Don’t blame the battery capacity just yet! This “false empty” phenomenon is often caused by temporary voltage drop under high current.

Lithium-ion batteries are widely used in various fields ranging from consumer electronics to electric vehicles and energy storage systems due to their high energy density and long service life. However, the potential fire and explosion risks of these batteries during storage make safe storage a critical issue that enterprises and consumers must attach great importance to. Proper storage methods can not only prevent accidents but also extend the service life of batteries and ensure safety in use. This article will explore in detail the safe storage methods for lithium-ion batteries and provide comprehensive guidelines to minimize risks to the greatest extent during usage and storage.

Lithium-ion batteries (LIBs) are complex electrochemical and mechanical systems, subject to dozens of international safety standards. In this FAQ, we will discuss key environmental aspects of LIB safety, review common safety standards for lithium-ion batteries, and consider the use of custom battery test chambers to ensure the safety of test personnel.

With the intelligent upgrading of industrial equipment and the advancement of the "lead-acid to lithium-ion replacement" policy, the demand for lithium-ion batteries in segmented fields has continued to surge. According to data from the Global Industrial Lithium-Ion Battery Market Report 2024 by GGII (High-Tech Industrial Research Institute), the penetration rate of global industrial equipment lithium-ion batteries will reach 45% in 2025. Among them, 24V, as the mainstream medium-voltage specification, will see an annual demand growth rate of over 30% in scenarios such as special equipment, robots, and medical devices. Currently, the development of 24V lithium-ion batteries presents three major trends: first, the prominent demand for customization, which needs to adapt to the power, space, and environmental requirements of different equipment; second, the lithium iron phosphate (LFP) system becoming the mainstream, occupying over 60% of the industrial market with its high safety and long service life; third, the integration of intelligent BMS (Battery Management System), where support for remote monitoring and fault early warning has become a standard feature. To help equipment manufacturers efficiently solve the technical matching, cost control, and compliance challenges in the customization and selection of 24V lithium-ion batteries, ETOP Lithium Battery, combining 23 years of experience in customizing lithium-ion batteries, has organized industry data and practical cases to compile this selection and procurement white paper. Focusing on core customization points (such as parameter definition, BMS design, and scenario adaptation), this paper provides practical references for technical teams in product selection and procurement teams in cost accounting.

In the actual use process, the change of the internal resistance of the battery is also affected by various factors such as temperature and SOC. This article is an overview of the research results of internal resistance characteristics in recent years by relevant technical staff of Guoxuan Hi-Tech.

Battery technology has always been the key to the next iteration of many consumer products. It directly pinches the pulse of the product in terms of battery life and portability. Any small step forward is a big step forward for consumer products. Of course, it is also extremely critical for automobiles. In the process of transforming to electrification, whether the power battery of new energy vehicles can be improved qualitatively will directly affect the pace of automobile development in the next decade. Previously, Toyota officials mentioned that among all new forms of battery technology, solid-state batteries are considered to be the closest to mass production. Its high energy density, high voltage and even bendable characteristics are far superior to traditional power batteries. Achieve strides. So far, how far has the solid-state battery developed, and how far is it from mass production? In this article, we will share some information with you in various aspects.

When it comes to pure electric vehicles, the biggest problem is probably the cruising range. Friends who drive new energy electric vehicles in the north know that the cruising range will be greatly reduced in winter. As a result, they did not dare to turn on the air conditioner for heating, so they could only endure the severe cold and shiver in the compartment. It directly leads to the extremely poor experience of new energy vehicles. To solve this problem, we have to rely on the battery management system. Today, the editor will talk to you about this topic.
