The Causes Of Thermal Runaway Of Lithium Batteries And Safety Precautions

  Thermal runaway is the main cause of battery safety problems, so what causes  thermal runaway  of lithium batteries?   First, the external factors of the battery. If the ambient temperature of the battery is too high, and the battery does not dissipate heat well, or the internal winding is poor, resulting in poor battery heat dissipation. In addition, companies need to pay special attention to another situation, that is, the battery spine is sometimes hot.  The metal spine of the battery has copper and aluminum and has a relatively good thermal conductivity. For circuits in components with some high heat sources, it is important to ensure that they are kept away from the battery spine to adequately dissipate heat.   Again, the internal factors of the battery. One is a micro-short circuit. There are two types of micro-short circuits.   One is the short circuit in the battery production process, including burrs; the other is the use of the process in t...

Why A Walk-in Explosion-Proof Chamber Is the Safest for EV Battery Pack Testing ?

  Lithium Batteries for electric vehicles need proper testing. While testing, battery explosion can happen so we need an explosion-free test chamber. In this article, we will discuss a very   useful walk-in explosion-proof test chamber . Using electric energy keeps growing steadily on earth. Lithium-ion batteries are chiefly utilized in such instances, so they’re studied from the previous decades, together with the intention to increase the degree of basic security ensured within their own performance. Anyway, basic protection problems remain, and the most important issue is to prevent the growth of poisonous incidents. These incidents might be affiliated with short circuits, including over-charge/over-discharge electrical currents and overheating. These risky conditions can cause exothermic chain responses in the storage technique, which may discharge hazardous or sterile gases and, lastly, catch fire. These issues need to get confirmed in lots of software and specifically wh...

IEC 62619 Safety Requirements for Lithium Batteries Industrial Application

  IEC 62619 specifies tests and requirements for secure secondary lithium batteries and cells used in industrial uses such as static applications. When there is   an IEC 62619 standard   specifying evaluation requirements and prerequisites of cells used in particular applications and will be in conflict with this record, the former takes precedence. Listed here are a few examples of software that use batteries and cells under this document’s scope. Because IEC 62619 covers, batteries for various industrial uses, it comprises these requirements, which might be typical and minimal to the several software. Electrical safety is included only as part of the risk evaluation of Clause 8. Regarding details for fixing electrical security, the end-use program standard requirements need to be thought about. This test applies to batteries and cells. If the battery is split into smaller components, the more compact device can be analyzed as the owner of this battery. The producer ackn...

How to Use and Troubleshoot Industrial Vacuum Drying Oven Properly? - Part 2

  We are aware a vacuum drying oven is just a box-type draining apparatus that dries dry stuff under non-positive strain. It employs a vacuum pump to remove moisture from the atmosphere. Therefore, a vacuum cleaner condition is shaped at the chamber, which lessens the drinking water’s boiling point and hastens the drying rate. The industrial vacuum drying oven gets the benefits of quickly drying particular goods, tiny contamination, and no injury for these dehydrated objects’ inherent high quality. However, do you know the vacuum drying ovens ought to be summoned before it’s properly used? Even as we realized,  vacuum drying  is commonly utilized in food, medicine, the lighting industry, chemical business, and other sectors such as low-temperature drying. It’s the benefits of quick-drying, external contamination, and no injury to this dehydrated stuff’s inherent high quality. To boost consumers’ efficacy utilizing the vacuum drying chamber’s effectiveness, the customer se...

Industrial Vacuum Drying Oven – Functionality and Benefits - Part 1

  Industrial vacuum drying ovens are incredibly versatile items with software from lab study, technology, and the marketplace. Even a vacuum drying oven is most commonly employed for brittle drying procedures, like drying miniature components or eliminating chlorine solvents. The very minimal strain environment additionally reduces oxidation throughout elimination. A regular vacuum can run at temperatures too large as 200C into 250C. To buy a higher-excellent  vacuum drying test chamber , some features you need to search for, in addition to suitable, programmable controllers and also a keyboard port. Vacuum toaster ovens can also be obtainable with technical features like mold restoration or residual petrol investigation to stop further drying. For drying rancid solvents, find a secure vacuum drying oven that was permitted for these particular products. An industrial vacuum drying oven can also be referred to as an industrial vacuum drier. A scorching atmosphere principally he...

Fault Diagnostics of EV Battery with Battery Module Test Equipments

  Besides ensuring vehicle occupants’ safety, the battery life needs to be maximized via the module layout and battery life management strategy. Running current, thickness, charge/discharge speed, and temperature all strongly impact battery life.  As a result of increasing time and cost pressure facing OEMs for the most recent generation of electrification technology, a brand new dedicated center was opened for comprehensive battery modules testing. The program drives which kind of battery module and package testing is necessary. Battery module and package testing  entail hardly any testing of the inner chemical reactions of their respective cells. Common performance-based tests comprise drive-cycles, peak power capacity, BMS software validation, along other application-specific characterization evaluations. Battery module test equipment is essential at every stage of the item life-cycle, such as R&D, production, and depot repair.   Challenges of Battery Module T...
