What is Energy Storage System
1.Why need Energy Storage System
Nowaday more and more countries and areas has the increasing bill of electricity using,and there still are lot of no gird areas,the purpose for energy storage system is to cut the electricity bill or solve the essential need for those no gird regions,that’s why we need ESS for our better life.
2.Consists of Energy Storage System
1.Inverter
The Inverter is a device that convert DC to AC voltage,as we known our appliances basically powered by AC voltage single phase or three phase,but the voltage from battery is DC,so we will need converter to change it for powering your devices or appliances.
2.Battery
The Battery is a kind of device can store and release electricity,now the battery type for energy storage system in the market mostly is Lead Acid battery or Lifepo4 Battery or NCM Battery,it can output DC voltage directly for some DC equipments.
3.Battery Charger
The Battery charger can charge the battery,because inverter is DC to AC converter device,therefore it can not charge battery,when the battery is out of power we will need charger to power battery with same DC voltage,now most of battery charger has combined into inverter.
3.The Working Process of Energy Storage System
1.Charging Stage
Battery can be charged by solar power or AC grid or other method as long as the way can generate electricity.
2.Store Stage
Electricity by battery charger and inverter convert to proper form to store into battery.
3.Discharge Stage
Then it can be released for your equipments or appliances via proper converter.
3.Applications
1.For High Electricity Prices
When in the day Electricity prices is high we can use the ESS as the main supply for your using,when in the night Electricity prices is low we can use the AC grid to power the battery and your normal using at the same time,that’s reducing your whole cost for electricity bill.
2.For No Grid
The energy storage system equip solar energy then it will be like a mini grid can always power your all devices.
3.For Unstable Grid
It can make sure you have no outage situation to protect all your equiments and ensure you have normal electricity using all the time.
4.Conclusion
Nowadays the ESS is essential for our normal power use,Eventually, we will move towards commercialization and consumer goods, and now our biggest challenge is how to ensure high-quality, low-cost, and absolutely safe products for the people in the world.
