Today, the high-voltage batteries used in electric vehicles all offer maximum safety and longevity. If you're still hesitant to switch from a gas-powered car to an electric vehicle (EV) because you're worried about the safety of your battery, don't worry! According to a number of reports, many people are very concerned about the dangers of electric vehicles and their high-voltage batteries. In fact, high-voltage batteries are very safe to use under normal operating conditions, and there are relatively few problems. In fact, the high-voltage battery on an electric vehicle is as simple, reliable and safe as the battery in an electronic clock. At present, the most widely used lithium-ion high-voltage batteries in electric vehicles are equipped with high-voltage contactors, which can safely and effectively disconnect the current under normal operating conditions.
As an industry-leading manufacturer, TDK offers a range of high-voltage contactors to meet the needs of high-current DC contactor relay applications. HVCS (High Voltage Contactors) are essential not only for electric vehicles, but also for charging stations, commercial vehicles (e.g. buses, trucks and heavy equipment), uninterruptible power supplies and renewable energy storage systems.

TDK has designed its high-voltage contactors with safety in mind. As an integral part of an electric vehicle battery disconnect (BDU), a HVDC contactor is part of a system that is used to disconnect the battery and extinguish the arc generated in the contactor in the event of an emergency or failure. These types of failures can include battery issues, mechanical issues, or damage caused by external factors. Battery Disconnect Device (BDU): Enables the connection of a power source or battery pack to the power system in an electric vehicle (EV). 】
By expanding TDK's portfolio of HVDC contactors, TDK has developed a new series of HVC43 products that is 30 percent lighter than its predecessor. The inflatable ceramic arc chamber is suitable for small current designs below 250A and can quickly disconnect and extinguish the high loads currently found in electric vehicles.
TDK high-voltage relay contactors are an important component of the vehicle's electrical safety system and an important component in the vehicle BDU controlled by the battery management system (BMS). In the event of a failure, the BDU must disconnect the lithium-ion battery to avoid damage to the battery. When this situation is severe, it can cause a fire or even **. Battery Management System (BMS): The electronic systems that manage EV rechargeable batteries to ensure that voltage, temperature, coolant flow (where applicable), and current are within safe limits, while redirecting energy back into the battery system. 】
In electric vehicles, high-power electrical equipment switches between open and closed states, and an arc is generated between the two contacts of the switch. In hazardous situations, this arc can be very destructive if not extinguished. TDK Merchant |TDK High Voltage Contactors|DC Power Contactor |High Voltage Relay Contactor|
As more and more consumers choose electric vehicles, there will be fewer reports of the very few safety issues that arise in exceptional circumstances, which will further drive the shift to an internal combustion engine-less vehicle environment. With the addition of a HVDC contactor in a high-voltage battery system, the safety of the vehicle will be further improved, and the on-demand power supply will be realized, and the charging speed will also be faster.
Continuing its efforts to develop technologies that improve the safety of high-voltage batteries, TDK quickly introduced the industry's first TDK high-voltage DC contactor design with improved short-circuit performance.
Today, car users don't have to worry about safety and convenience, and they can choose their vehicles according to their values. This means that drivers get the same safety and performance experience as traditional gas-powered cars, while also helping to improve the environment, which is a win-win situation for all!
