What are supercapacitors and why not use them instead of batteries? Supercapacitors have several advantages over batteries (eg. L-Ion): they (dis)charge far faster, have a longer lifetime and are non-flammable. And thanks to recent innovations they can also store sufficient amounts of energy per kg to be used as ‘batteries’. 247 Energy’s SuperCap-based energy storage is...Continue Reading
Charge speed is our focus in this “watt (what) to look for when selecting your professional energy storage”. The C-rate is the unit used to measure the speed at which a battery is fully charged or discharged. Eg. charging at a C-rate of 1C means that the battery is charged from 0-100% in 1 hour. A...Continue Reading
Warranty conditions are our focus in this “watt (what) to look for when selecting your professional energy storage”. Warranty conditions on energy storage can range from 5 to 10 years. However often it is pro-rated from 100% at the start of year 1 to 50-60% at end of the warranty period. This is often also linked...Continue Reading
In our “watt (what) to look for when selecting your professional energy storage”, we shed a light on your ROI. ROI (return on investment) is what matters if you invest in energy storage to trade or help stabilize the energy grid. There is more to determining the ROI of your energy storage infrastructure than just your...Continue Reading
In our “watt (what) to look for when selecting your professional energy storage”, we shed a light on your safety. Thermal runaway is a chain reaction within a battery cell that can be very difficult to stop once it has started. It happens when a battery’s internal temperature rises to the degree where a chemical reaction...Continue Reading
In our “watt (what) to look for when selecting your professional energy storage” today we shed a light on power density. The battery’s ability to store energy is measured by its energy density. i.e., a battery with a high energy density can store a lot of energy. The battery’s capacity to absorb and deliver electricity is referred...Continue Reading
In our “watt (what) to look for when selecting your professional energy storage” today we shed a light on battery cooling. Lithium-ion batteries include an integrated cooling system to keep them functioning safely. The battery cells are kept cool as a result, preventing overheating. Cells that are overheated may ignite and explode. Additionally, this active cooling...Continue Reading
In our “watt (what) to look for when selecting your professional energy storage” today we shed a light on cycle life of a battery. Each round of full discharge and then full recharge is called battery cycle life. As you use your battery and recharge it, it slowly loses the ability to return to its...Continue Reading
In our “watt (what) to look for when selecting your professional energy storage” sessions, today we shed a light on DoD. Depth of Discharge (DoD) refers to the size of the battery that is actually available for use. For many battery technologies, the state of charge is often limited to the range between 15% and...Continue Reading
