How To How To Maximize The Safety Of Advanced Battery Systems Something For Small Businesses

In advanced battery systems, the quality of the power electronics components determines the quality, functionality, and reliability of the final product. Emphasis is placed on the use of wideband gap semiconductors and improved power topologies in the latest battery power management and charging systems. In advanced electronics, if the safety system does not operate quickly and reliably, the entire battery system can suffer a catastrophic failure that can seriously affect the product and its users.

The need for improved energy storage systems

Almost every advanced application space today requires a next-generation battery system. Smart grid energy systems require more storage, such as advanced electric cars, and these requirements are closely related. Each space has its own needs, but safe, reliable, and economical energy storage is its core requirement.

In critical life areas such as automotive safety, the importance of having an automatic safety subsystem is vital. The battery system of the new energy vehicle is equivalent to the fuel tank of the fuel car because the storage of energy needs to be safe. There is a lot of power in modern batteries, and a catastrophic failure would certainly involve thermal runaway (fire). The higher the publicity on the light of new energy vehicles, the more attention can be drawn to this danger, which is why safety issues should be addressed to avoid the adverse effects caused by public new energy vehicles.

In advanced battery systems, higher battery density requires appropriate safety protocols and equipment, as power levels are very challenging in managing short-circuit problems. To build a robust and safe method that helps ensure reliability over a given vehicle lifetime, manufacturers must integrate high-performance components into their designs.

The function of fuse and contactor

A fuse or similar device is a necessary circuit protection part that can protect the system by disconnecting the circuit under certain conditions. There are many types of fuses, but the main component of each wire is an engineering wire, usually metal, which is evaluated for failure (melting) in a controlled manner in the event of a temperature increase due to a short circuit. This disruptive protection ensures the safety of the course by completely cutting off the power supply.

However, this short-circuit has some disadvantages, the most prominent being that the power supply circuit under load does not necessarily have constant current. In designs requiring high power pulses, a wide range of currents encourages the use of higher current fuses, which can avoid causing unnecessary trips, but this makes the system more susceptible to overheating and thermal problems. This and irreversibility of fuses, has led to the increasing use of electromechanical safety devices, such as circuit breakers, which can because they do not rely on the functionality of destructive components.

A contactor is another electromechanical protection device, but it differs from a circuit breaker in that the contractor does not interrupt the circuit. A contactor is a device designed to be connected directly to a high-current load and operated by external control with a high-power switch. In situations requiring high skill, the power connector can be a circuit reset and preferred in the presence of high current levels. Although similar in operation to relays, contactors differ in robustness and in the usable function of controlling and suppressing the arc produced by switching.

In terms of battery systems, high-voltage contactors provide safe circuit continuity for hybrid and new energy vehicles, charging systems, and high-power industrial applications. These types of contractors can connect and reconnect circuits quickly and safely, managing arc and current situations. For example, in new energy vehicles, ordinarily open contacts securely connect the battery pack to the system and disconnect when the car is not in use.

Faster and more accurate solutions

A variety of circuit protection solutions can disconnect circuits faster than fuses and are closer to normal operating conditions without causing tripping, resulting in less damage than using a hot fuse.
