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: Solar energy products, that is, I would like to open a home solar products Daquan
- I have two sets of solar home, one is Huang Ming, a sijimuge, later a temperature than the Emperor Ming of the seems to be a little higher, are also good, but home Taiwan Himin's high, I want to buy one, want to try another brand is not the same effect
- Q: How to make better use of solar energy
- According to the history of the use of solar energy, solar energy has been used for more than 3000 years of history. The use of solar energy as a source of energy and power, only 300 years of history. The real solar energy as a much-needed supplementary energy in the near future, the basis of the future energy structure, it is a recent thing. Since 1970s, the rapid development of solar technology, solar energy utilization
- Q: How to do a good job of solar water heater marketing?
- Two, energy saving (cost savings): the impact of solar water heater life components. About the use of solar water heaters for heating homes, can save daily for heating water electricity, gas costs 90%, can reduce household expenses, to the society, can reduce our province limited energy resources consumption, the energy and ancillary facilities for agricultural and industrial production, have greater social benefits.
- Q: What are the functions of the new vehicle negative ion solar charging humidifier?
- Quite a lot of functions, when the car humidifier, anion purification car air, solar charging, you can also add the essential oils when the car fragrance.
- Q: PV solar products market sales
- According to the State Administration of taxation policy released last year, from October 1, 2013 to December 2015 3l, according to the 3% levy rate calculation. In Takamatsu as an example, if a month sales of 30 thousand, that he should pay the tax is 30 thousand x 3% x 50%=450 yuan.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
- Q: Home solar heating products can not mature?
- 1, the local climate: the solar water heater solar tube is not winter frost, but many people will find that in addition to solar tube other basically frozen broken in the actual use of the process, all the cold area, far distance roof is not recommended, the summer hail smashed zirendaomei. Before taking a bath before half a bucket of cold water, it is really a waste;2, installation conditions: the water pressure is not good, the floor is high, ready to install solar energy and electric hybrid proposal wash sleep. The related auxiliary equipment comprises a booster pump, a controller, will force you to spend a lot of innocent money, you are hard to feel the donkey3, economic price: the use of the price, the price of solar water heater in more than 3000, 1500 yuan, 2000 yuan while the gas water heater, solar electricity, but the experienced friends all know no electricity solar still can not be used, all can not talk about energy saving. On the use of the cost of natural gas pipeline gas prices in the province, followed by electricity tariffs, the overall cost of speaking, to buy more than 1500 yuan solar electricity tariff equivalent to 3000 degrees, enough for a few years of use.
- Q: Are solar panels now in use?
- Servo drive, also known as "servo controller" and "servo amplifier", is used to control the servo motor
- Q: The advantages and disadvantages of solar energy?Want to buy solar energy solar energy what is bad? Know about
- 2, slow heating, temperature can not be stored, no storage function,Because now the market does not rely on solar energy storage battery, so no matter how good the sun, onlyTo provide the energy required for the day, the next day must be used on the rainy day electricity heatingWater heater fee
- Q: Outdoor solar energy products, how can we do the process of IP65 level, the design of the water which should be noted that what? Beg enlighten heroes!
- Third, the less the number of parts as possibleFourth, when the whole is a way to allow glue
