On the road to zero emissions
Components for safer, more reliable electrical generation, storage, and charging
Omron has the power relays, sensors and connectors required for modern energy generation, storage and use.
As a global manufacturer with key competence in sensing and control technology, Omron provides an array of dependable and highly qualified electro-mechanical components that drive the performance, reliability, and safety of electrical equipment. For commercial buildings which account for a large amount of energy consumption, efforts are being called to reach “zero emission”. In residential, households are increasingly generating power to recharge electrical devices and vehicles. In both cases, this is achieved by the installation of stable renewable energy sources such as solar photovoltaic power generation systems and storage batteries. With these efforts, we are coming closer to realizing a decentralized society that does not rely on conventional power sources.
Featured applications
PV inverters
Recent development of mega-solar photovoltaic power generation systems is looking more into increasing the capacity of decentralized PV inverters to maximize power generation and reduce maintenance costs.
As PV inverters are being tailored to handle more and more power, the design of heat dissipation becomes challenging. To solve that, Omron has developed new lines of relays G9KA and G7EB that have the lowest contact resistance in the market. The new models minimize loss and generate less heat, allowing the designers to use smaller cooling fans and smaller heat sinks, thus reducing overall costs and improving efficiency.
Energy storage systems
Homeowners and businesses are now turning to storage batteries to increase solar self-consumption.
Furthermore, there is a trend in using high-capacity and high output batteries to recharge electric vehicles and provide back-up power. The new high capacity DC relay, G9KB, 50A, 600VDC with bidirectional switching allows for use of one relay for electrical charging and discharging where in the past two relays connected in parallel were required. The G6QE 36A, 250 VAC miniature high switching current relay is used to disconnect from the power grid in the event of a failure in the primary power source input or equipment faults. The new G2RG-X compact, high voltage DC power relay is designed with 500VDC 10A switching capacity, which was developed for inrush current prevention in equipment such as ESS.
Stationary EV chargers and V2H (vehicle to home)
With the growing demand of electric vehicles (EVs), the charging infrastructure is increasing, including the number of EV charging stations in various locations at homes and across cities (Level 2). There is a growing trend in developing EV chargers with high-capacity output to achieve shorter charging time.
The G9TB 120A, 276VAC AC latching relay is compact in form factor for a minimal footprint and requires less power consumption for energy efficiency. It is used to disconnect from the power grid in the event of a failure in the primary power source input or equipment faults. The proliferation of solar photovoltaic power generation systems and electric vehicles across homes has led to an increase in EV batteries for stationary storage applications. For such applications, DC charge and discharge control are carried out. The G2RG-X power relay with 500VDC 10A switching capacity with a bypass circuit is used to protect the equipment against inrush current that occurs at the start of charging. G5NB relays are used in circuits where the insulation resistance between the DC input line and the ground is measured before the EV charger starts. If the insulation resistance is greater than the specified threshold value, the operation stops as provided by the safety standards.
