1. Requirements for large-scale UPS power supply on site and environment (1) The equipment installation site should be an “industrial type” hard cement-type horizontal floor. If an anti-static raised floor is used, it needs to be designed according to the weight of the UPS on the basis of considering the average load of the floor. Make …

At present, different manufacturers have different technical routes for string inverters. There are unipolar and two-level inverters. The usual practice is to use a two-level electrical structure. The front stage is a boost booster, and the rear stage is a DC-AC inverter. Variable, the maximum power tracking MPPT is generally placed in the front stage. …

At present, most of the batteries of passenger pure electric vehicles have abandoned lithium iron phosphate, a cathode material, and switched to ternary lithium materials. The main reason is because of higher requirements for battery performance, that is, higher cruising range. Require. It has been more than two hundred years since the development of chemical batteries, and …
The car battery is an essential part of driving, without it, the car cannot start, so it is very important to ensure that the car battery is charged. How to charge the car battery is the key to car battery maintenance, so how to charge the car battery? Let us briefly introduce the charging method of …

Uninterruptible power supply is a system equipment that connects batteries (mostly lead-acid maintenance-free batteries) with the host, and converts DC power into city power through module circuits such as host inverters. There are large and mini UPS. Large ups are used in mining, aerospace, industry, communications, national defense, hospitals, computer business terminals, network servers, network equipment, data storage equipment, …
Electric vehicles are regularly in the news these days, largely because air quality has become a hot topic. Traditional fuel vehicles are one of the main sources of pollution, so governments around the world are trying to vigorously promote electric vehicles. As an energy source for electric vehicles, battery technology has always been one of the …
Power battery recycling The types of power batteries used in new energy electric vehicles include lithium iron phosphate batteries, ternary lithium batteries, lithium cobalt oxide batteries, and nickel-metal hydride batteries. Among them, lithium iron phosphate batteries and ternary lithium batteries are widely used because of their excellent performance, better performance, lower cost, and lower cost. Power batteries are generally …
Russia and Ukraine together account for 70% of global neon gas production. Neon gas is an important raw material for chip manufacturing. The global semiconductor industry, especially the automobile manufacturing industry, has been worried about the “chip shortage” that will last for a period of time. Now, it is also worried about the danger of a shortage …
