Lithium Battery BMS / PCB / PCM
Li-ion cells should always be used with a protection circuit to prevent the cell from over charging or over dis-charging. Choosing the correct circuit and applying it appropriately is vital to the longevity your batteries and your own safety.CNBM test each Cells and BMS/PCB/PCM before manufacturing and promise it is functional and safe.
BMS / PCB / PCM is the "heart" of Lithium battery pack. BMS (Battery Management System) is any electronic system that manages a rechargeable battery (cell or battery pack), such as by monitoring its state, calculating secondary data, reporting that data, protecting the battery, controlling its environment, and balancing it.

- Q: How to make solar energy?
- Finally, cut a large hole in the box and put on a plastic wrap to absorb sunlight. A simple solar water heater is finished. I do the "solar water heater" to the teacher. The teacher said: "you have not put black metal bottles, so absorb sunlight more slowly, the water temperature is not easy to rise." So, we put the bottle of black metal.
- Q: Product category and comparison of solar thermal utilization
- Why choose a new type of efficient flat plate solar water heater (device) system?In recent years, the use of solar thermal products in China has been rapid development. In the solar water heater manufacturing, use and market share, China has far ahead. However, due to the use of solar thermal products in domestic vacuum tube based, in full swing in the development of the industry, but also exposed a lot of worrying problems.
- Q: What is the future of solar power
- Residents issued 1 kwh of electricity, the state subsidy of 0.42 yuan; the national standard for the purchase of electricity from the desulfurization of residents with endless self generating electricity, the price is $0.42 per degree. To install and use a set of distributed photovoltaic power generation system with an average of 1 kilowatts of installed cost about 10 thousand yuan, if the 8 kilowatt system daily generating capacity of 30 degrees, 5 degrees every household consumption (no more than a price of 0.52 yuan), about 8 years to recover the investment. In accordance with the same calculation method, 10 kilowatts of distributed photovoltaic power generation device to recover the cost of 9-10 years. Family photovoltaic power plant to recover the cost of an average of between 8-10 years.
- Q: How much does it cost to install solar energy in rural areas
- Four look at the brand, service. The solar water heater host outdoors year-round by professionals need to withstand exposed to wind and rain, maintenance, maintenance. At present, there are 4000 domestic solar water heater factory, as the country has not yet unified solar water heater testing standards, some of the quality of the product does not pass, installation services are not in place, to bring trouble to users. Buy solar energy is not only a product, but more importantly, service". Therefore, we should choose the strength of the brand name of professional manufacturers of products, such manufacturers to install service personnel are generally through professional and technical training, service and thoughtful, so that you do not worry, get the best protection.
- Q: Solar energy application technology, there is no prospect
- At present the solar energy situation is not optimistic, the Americas and Europe has Chinese solar "double reverse" and China internal and not good, can not be the own production of solar energy products consumed, resulting in pile up in excess of requirement. Therefore, many Chinese solar manufacturers have closed down.
- Q: What are the references of the solar automatic tracking system
- This paper studied the sun automatic tracking of the independent photovoltaic power generation system based on solar photovoltaic power generation as an important way of utilization of solar energy, the development prospects are very broad. At present, the photovoltaic power generation system with fixed form, the power system has the disadvantages of low power efficiency, high cost and difficult to promote.
- Q: What are the current domestic solar energy products, which practical
- Photovoltaic power generation system is mainly composed of solar cells, batteries, controller and inverter, the main part of solar cells. In the application of more public amenities such as solar street, home of the little, of course you can install the system of solar photovoltaic panels at home, 1W about ten dollars, plus the controller, you can see if you are able to supply applications at home how much money.
- Q: Solar heating easy to use? Has anyone used it
- If your house has a little heat preservation effect, the heat collector area is not enough. The first is fraud, very high! Followed by the heat collector is often no place to swing! Again, so many collectors, the heat generated in the summer there is also a problem
- Q: The steps of making solar technology stubs
- 1 with a brush clean eraser material: big eraser, waste brush.Tools: scissors, glue.
- Q: Solar energy items in daily life
- The solar water heater, solar flashlight, solar micro kitchen, decoration, solar car
