Summary:
The battery pack consisting of high-voltage and multi-cell batteries is mainly used in electric vehicles, hybrid vehicles, electric bicycles, power tools and other equipment. Lithium-ion batteries are widely used due to their high energy density. These high-energy battery packs require a good battery management system for detecting the voltage of multiple cells and the battery temperature. Without this monitoring function, the system may run out of temperature and cause the battery to explode. The battery pack's data acquisition IC is used to measure the voltage of multiple cells (usually 12 knots), but they scan and measure at most two temperature points. This article describes a low-power circuit that measures the temperature of up to 12 thermistors. It powers and configures the multiplexer, and in the absence of temperature measurements, the multiplexer enters shutdown mode to save power. The low-power circuit shown in Figure 1 scans and measures each cell inside the battery pack. Two MAX382 multiplexers switch 12 thermistors to the input of the data acquisition chip (such as the MAX11068 or MAX17830). Collect 2 thermistors for a total of 6 groups. The data acquisition IC provides thermistor bias and powers the multiplexers and controls their switching and enable/disable.

Hotel Door Lock Motor also known as Smart Hotel Door Lock Motor, perform operations in the hotel door lock, at this point, the cardholder simply throw the door handle to open the door. That is to say the hotel door lock motor is used to open the door.
Induction door lock is a infrared sensor through induction of new security equipment, widely used in hotels, hotels and clubs, and other areas of the smart IC card, rf door lock, generally divided into induction induction door lock system, provides the high quality for the hotel induction door lock system. Induction in the European and American countries have been developed to a certain extent, has been a measure of the quality of life index of height and life.
Operating temperature range:
Hotel door lock motor should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a Smart Hotel Door Lock Motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
lock motor should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of Smart Hotel Door Lock Motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.
â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
