Battery Storage Switching Solutions

Battery Storage Switching Solutions

Batteries have been used for energy storage for 100 plus years. Durakool’s long heritage of switching DC power for electricity generation & storage was initially with lead acid low voltage DC and more recently, lithium-ion HVDC battery systems. Our DSC contactors switch up to 2000A at 60VDC & our DEVR series can carry as much as 1000A at voltages as high as 1000VDC. Typical applications (also for our Temperature & resistor solutions) include telephone exchanges (48VDC) and solar or wind power buffering. DEVRs are also used for portable, emergency, field back-up power installations where reliability & low weight are important.

EV Battery Charging Applications - Relays & Contactors

EV Battery Charging Applications - Relays & Contactors

Electric vehicles, in one form or another, have been around for over 100 years. Early vehicles used lead acid batteries and worked at 6V and upwards. Lead acid EV’s are still around in the 21st century in large numbers (think forklift trucks or golf carts, for example) but Lithium based batteries are replacing them, especially in applications such as cars, vans and trucks.

Blowout Magnets - What They Are & Why Use Them?

Blowout Magnets - What They Are & Why Use Them?

The one big problem facing anyone switching a high current DC load is how to turn off the arc which is generated when the switching contacts open. By comparison, switching AC is easy, the arc is self-extinguishing every time the waveform crosses zero which happens several times, depending on the AC frequency, whilst the contacts open and move apart.

AUTOMOTIVE HIGH VOLTAGE - TWO IN ONE!

AUTOMOTIVE HIGH VOLTAGE - TWO IN ONE!

NEW 120A 1000VDC Double Pole Contactor - DEVR10DP! Two separate 120A/1000VDC HVDC contactors in a single package, which may be switched together or independently. The two-in-one configuration greatly reduces space required and the complex (and costly) interconnections needed for traditional standalone pre-charge contactors.

HVDC Contactors and Failure Modes

HVDC Contactors and Failure Modes

A useful Durakool technical presentation regarding correct and incorrect HVDC contactor positioning. Typically an electric vehicle (EV) will have two main contactors positioned in the feed from the battery to the electronic motor drive. There may be others used as part of the pre-charge, discharge or charging circuits. The principle function of the main contactors is...
