The BMS wake-up circuit is required to restart the BMS when detecting the charger in charging the battery pack. The regular method is spanning the sampling circuit between the battery anode P+ and cathode P−, or connecting a detection circuit … Continue reading →

A flashing red light is similar to a solid red light in that respect. Because it flashes, however, you can drive through the intersection once the coast is clear, instead of waiting for the light to turn green. In that … Continue reading →

Stormbreaker is an enchanted axe of Dwarvian manufacture, forged from Uru on Nidavellir with the ability to summon the Bifrost. After Mjølnir’s destruction, the weapon was used by Thor. Is Thor’s axe stronger than hammer? Although Stormbreaker and Mjolnir have … Continue reading →

Alkaline batteries have a higher energy density and longer shelf-life. Voniko AAA bulk batteries are an excellent example of this. With a shelf-life of up to ten years and seven to nine times the power of ordinary carbon batteries, it’s … Continue reading →

That’s because nanocellulose is a material with a lot of potential applications – the whiskery, needle-shaped particles are lightweight, stiffer than Kevlar, stronger than steel, non-toxic and, perhaps best of all, completely renewable and biodegradable. What fabric is stronger than … Continue reading →

Polyethylene (PE) plates are made from ultra high molecular weight polyethylene (UHMWPE), which is a ballistically resistant plastic. PE plates are made of many layers of the PE material that have been compressed and heated until it forms a hard … Continue reading →

Mass is the quantity of matter in a physical body. It is also a measure of the body’s inertia, the resistance to acceleration (change of velocity) when a net force is applied. An object’s mass also determines the strength of … Continue reading →

Stone is far harder than metal, but more brittle. This means that it totally ignores hits that may dent metal, but harder strike which may have left a large dent, or even a small hole in metal may shatter the … Continue reading →

“We’re not trying to defeat impacts with only the elastomer, as the elastomer alone isn’t enough to stop them, but it can slow bullets and bomb fragments down, so whatever hard material is behind the soft elastomer can handle them.” … Continue reading →

Albert Einstein first predicted the existence of black holes in 1916, with his general theory of relativity. The term “black hole” was coined many years later in 1967 by American astronomer John Wheeler. Who found black hole first? Objects whose … Continue reading →

An energy storage system (ESS) is a complex electronic equipment that has the capacity to control energy flows in a home electrical system. What is ESS energy storage system? An energy storage system, often abbreviated as ESS, is a device … Continue reading →

Hyaluronic acid is well known for its skin benefits, especially alleviating dry skin, reducing the appearance of fine lines and wrinkles and speeding up wound healing. It can also help relieve joint pain in people with osteoarthritis. Can I use … Continue reading →

If you do add too much muriatic acid, your pH levels can dip dangerously low, and your pool water can cause rashes and eye irritation. Low levels of pH can also damage metals in your pool like ladders, railings, screws, … Continue reading →

Lemons are extremely acidic. Any chemical with a pH less than 7 is considered acidic. Lemon juice has a pH of around 2.0, ranging between 2 and 3. To put that in perspective, the pH of battery acid (sulfuric acid) … Continue reading →
