Analysis the internal working principle of intelligent battery

Source: 2020 - 04 - 14 20:05 hits: the internal working principle of intelligent battery 'battery is a kind of wild animals, is also a kind of artificial intelligence,' said one person on the battery assembly. Domestication need to understand the nature of the battery. As an ordinary or clumsy battery couldn't communicate. Weight, color and size does not necessarily reflect his charging status and health. Users of the battery is very generous. They just to charge it, but can't guarantee it can work in the expected time. Most laptop batteries, or similar devices are 'smart', which means that the battery, the equipment and the user can communicate with each other to a certain extent. Manufacturers and management definition of 'intelligence' each are not identical. Some people are clever, you just need to add a chip, with the right algorithm to control the charging charger. But the smart battery system BBS, points out that intelligent battery must show charging status. The battery is equipped with a microchip, can communicate with the charger, to inform the user about state, for example showed that the charging status. Most intelligent cells work by coulomb counting, this theory can be traced back to 250 years ago, when Charlie Augustine - DE coulomb 'coulomb's law is established for the first time. The picture above shows a fuel counter, which is used to measure the energy of the inflows and outflows. Save energy is by charging status. There are several types of intelligent battery, each one has its complexity and cost. There will be no additional components basic batteries in addition to the chip. Chip control charger in the right algorithm simply. Browse the intelligent battery BBS, these batteries are not smart. So, what makes the battery become smart? The SBS BBS said, intelligent battery SoC display must be provided. Benchmarq provide fuel metering technology for the first time in 1990. Today, some manufacturers also offer two IC chip, one and two, known as the system management bus ( SMBus) 。 Single bus transmit information through a single bus system lines. But a look at carefully, the battery can still work through three wire. The cable is to provide the clock information data, and the positive and negative of the battery. To be on the safe side, most of the battery manufacturers will increase a additional wires to sense temperature. A single bus system storage battery information, can read the battery voltage, current, temperature, such as charging status information. Due to relative to the hardware, a single bus system power consumption is relatively low, so much for not too complex, is more sensitive to price products, such as radio, a digital camera and a portable computer devices. System management bus system management bus represents the electronics industry standardization of a set of communication protocol and a set of data. Nowadays, Durace/Intel standardization of the use of the intelligent battery has since 1993. The battery is composed of two separate wires, a used to transmit data, the other is used to provide the clock information. A set of system management bus contain information that is permanent and temporary. Manufacturers to weave some permanent data to the cell, including ID, battery model, name of manufacturer and the manufacturer of series of data. Temporary data is generated during the application, including the calculation, the user's system assembly and maintenance procedures. Some of the data is stored, others will be updated with the battery life. Although smart battery with the battery status and record the advantages of using information, but also has many shortcomings. Cost will be increased by 25%, need complex charger, need regular calibration, we can only read and not the actual working hours for charging status.
