In the context of global warming, carbon neutrality has gradually become a global consensus and entered a period of accelerated development. As the chart below shows, since 2019, major countries and economies around the world have released carbon neutral plans. In the economic chain,

Inverter is the direct current (battery, storage battery) into alternating current (generally 220V,50Hz sine wave). It is composed of inverter bridge, control logic and filter circuit. Widely used in air conditioning, home theater, electric grinding wheel, power tools, sewing machine, DVD, VCD, computer, TV, washing machine, range hood, refrigerator, video recorder, massager, fan, lighting and so on.

Before installation, we should first check whether the inverter is damaged during transportation.

The physical stability and pressure resistance of steel material is much higher than that of aluminum shell material. After the design structure optimization of various manufacturers, the safety device has been placed inside the battery core, and the safety of steel shell column lithium battery has reached a new height. At present, the majority of notebook computer battery cells are made of steel shell as the carrier.

Battery aluminum shell has high specific strength, specific modulus, fracture toughness, fatigue strength and corrosion resistance stability.Because of the characteristics of low density aluminum alloy material, non-magnetic, stable alloy at low temperature stage, less than the magnetic field resistance, good air tightness, and rapid attenuation of induction radiation, it has been widely used in aviation, aerospace, high-speed trains, machinery manufacturing, transportation and chemical industry.

Good safety performance: Because the soft-pack lithium battery is packed with aluminum-plastic film, the soft-pack lithium battery will not explode in the case of safety risks, but only blow up or crack.

First, the discharge current should not be too large, too large current will cause the battery internal heat, may cause permanent damage. On mobile phones, this is not a problem, can not consider. The larger the battery discharge current, the smaller the discharge capacity and the faster the voltage drops.

Lithium iron phosphate battery is a secondary battery, the main direction is power battery, compared with NI-H, Ni-Cd battery and lead-acid battery has a great advantage.

48V small home energy storage integrated machine, floor type, for home TV, computer, air conditioning, lights and other power supply, can also be used as an uninterruptible power supply, suitable for off-grid energy storage system, output constant frequency, constant voltage AC power supply. In normal operation, single-phase AC power supply is provided. In case of failure, the battery bank provides rated power to the inverter without interruption.

SOX: The full name is State Of X, the state description of the battery, H is English Health,C is capacity, P is power, E is energy, a bit like the parameters of the engine, such as displacement, power, energy, running time, etc.

Standardization: 18650 battery is the earliest, most mature, the most stable lithium-ion battery, Japanese manufacturers have accumulated a high level of consistency, a single battery is easy to replace in case of problems.

The weight energy density of lithium-ion batteries is generally 200 ~ 260wh/g at present; Lead-acid batteries are generally in 50~70wh/g, nickel-metal hydride batteries in 40 ~70wh/ kg. That means the other two are three to five times heavier than lithium-ion batteries for the same capacity. Therefore, in the light weight of energy storage device, lithium battery occupies absolute advantage.

Presumably everyone is curious about the difference between Costar and SAN, so let's analyze it. Costar has a great influence in China and is the second listed UPS company in China. Sante is more common abroad, Sante was acquired by an American company. They are all well-known brands.

UPS power supply is also UPS uninterruptible power supply. Simply put, it is a device that can continue to provide uninterruptible power to electrical equipment when the power is cut off to ensure that the equipment can work normally.

With the rising voice and rapid development of new energy, energy storage power is also gradually mentioned on the future agenda. So what is energy storage?

The first category: according to the type of electrolyte, including: alkaline battery, electrolyte mainly potassium hydroxide fire solution based battery: such as: alkaline zinc manganese battery (commonly known as alkali manganese battery or alkaline battery), cadmium nickel battery, nickel metal hydride battery and so on. Acid batteries, mainly sulfuric acid solution as the medium, such as zinc-manganese dry batteries (some consumers also called acid batteries), seawater batteries, etc.; Organic electrolyte battery, mainly with organic solution as the medium of the battery, such as lithium battery, lithium ion battery, etc.
