New description: • [New technical field] This creation side is based on a kind of hierarchical battery management _, especially refers to a digital communication interface that can manage battery management and is provided by DC potential isolation components. Construct a social transmission and transmission circuit, directly connect the battery core low voltage and high voltage signals in the digital display of each battery pack, and filter the data through the hierarchical management module group and the terminal control module. Layer management structure [Prior technology] • The current battery usage of electric vehicles often makes the battle position communication interface as the control and charging of the electric vehicle power system, and monitors the residual power of the battery and other working conditions. However, in the development of electric vehicles, the increase in battery capacity and battery power, under the consideration of the optimal battery capacity combination, the use of multiple strings and battery packs has become an inevitable trend in the development of electric vehicle power systems. Strings and battery pack replacements have also become one of the digital monitoring factors. Now 7 use the battery as the main power system, or the backup of the electronic, motor Most of them have already monitored the state of the digital Hi-side battery. Through such a digital communication interface, not only can the electronic 'electrical equipment of the electric Luli use end estimate the residual battery power, but also the appropriate 's not' when the battery is abnormal. Avoid the dangers caused by abnormal battery; since the large battery packs used in the past are mostly used, lead-acid batteries, this is because the previous (four) battery (LithiumBasedBattery) has a certain risk, and it is used for explosion and fire when used in large batteries. The risk is unacceptable, and it is because the battery has the advantage of low price and low price. In such a ship acid battery system, due to the acidity of the wrong acid battery, it is resistant to overvoltage and low power. Electrolytic water and heat generation to solve the problem of slight overcharge. In the 4-port I power battery system, the battery monitoring system focuses on the monitoring of battery capacity, and there is no need for battery voltage balance and single battery bee monitoring. It can make the (4) single digit 5 M348417 face communicate with the electronic and electrical equipment at the use end; but with the electric car and lithium With the development of batteries (LiFeP04 • battery), the functions required for battery monitoring systems are no longer just the monitoring of battery capacity. In the use of electric vehicles, battery weight is one of the important factors of electric energy efficiency, how to reduce the weight of the battery to increase the effective The load capacity, or effective endurance, has become an important factor in the development of electric vehicles. But the 疋 铁 铁 battery or the improved Li-Mn battery, although in safety and work To meet the needs of electric vehicles or large power systems, but due to the low internal resistance of lithium iron batteries, or lithium short batteries, and the high efficiency of charging, these safe warp battery pairs still need overvoltage and low power repair. Pressure protection to ensure their service life; because of the large power system, and because of the economic capacity of the lithium battery itself, it takes dozens to thousands of battery cells to live in a large battery system. The way of the road achieves the required jade voltage and battery capacity. Such a battery pack towel, except for the battery. In addition to the voltage difference formed by the series connection, it is necessary to monitor the voltage of each battery. It is necessary to form a battery module. In the past, the battery protection module has a limited number of battery cells and is based on traditional standards. The industrial interface (4) Na Na), or the regional interconnection network (CAN2.GB) commonly used in automotive electronic systems, can meet the needs of monitoring and communication. ❿Please refer to the figure-, for the direct serial connection of the practice, the direct serial digital interface with isolation circuit can solve the working reference voltage is not __, the direct serial connection digital interface, also makes the battery (four) modular The principle and maintenance, but because it is applied to the large power battery pack, the data transmission of the battery status is shown in the figure when the group is used. Even if the high-speed transmission mode is enabled, it takes U3 seconds. It can be seen that the transmission rate is 192_PS, and each octet data needs u ^ the time of 'the downlink command is composed of 4 octets, and the battery monitoring protection module has the maximum response (the delay time is 5ms, therefore The mutual communication time required for the entire battery pack is (small (4)2) /19200+_5) *just =! 53 seconds), which is based on an electric vehicle that may be completely dependent on power operation, or a large 6 M348417 type backup power system (UPS) The electronic and motor systems that need to monitor the battery status in real time cause doubts about the operational reliability. Previously, digital interface patents related to battery management, in the digital information integration interface, whether using a single-wire (〇ne-Wire) for controlling network connections or star connections. MaXim/HDQBUS, Ti), or two-wire (SmartManagementBus, -.Intel / CAN-Bus, Controller Area Network) transmission interface, using a single battery management module. As the core of decision-making, or using the parallel network As each other's communication, as the basis for each battery module decision. Therefore, as can be seen from the above, the use and management of the conventional large power battery usually have the following problems: 1. In the large power battery pack, in addition to high voltage and large capacity, the danger of personnel operation is caused, and The price and weight of the power battery must be properly cut to reduce the cost of general maintenance. 2. Another problem with large power batteries is the use of a large number of battery cells, because the power release when considering the battery different · f 'the number of direct connection of the battery core has safety considerations, and also -, the generation of the battery The need for monitoring during electrical production. The increase of battery capacity in the county, the monitoring module, and the amount of monitoring dragons will also increase; and the increased amount of listening, not only occupies the interface resources of the electronic and electrical equipment used in the power use terminal, but also enables the battery supervisor (four) to obtain The time delay of each battery data may also differ from the reference time point of each battery data. 3. In addition, the working reference voltage μ of the protection board of the battery pack is connected in series, and as the series voltage increases, the reference voltage difference of X may be high, 500 volts, and the county phase pure domain interconnection control network (c 〇ntr〇uer-_ network, cΑΝ seven us), or a star connection network (such as 7 M348417 'network) is no longer available. 4··Regional Interconnection Control Network “Center Control Group” (Center Cafe). It is necessary to monitor many components outside the battery in real time, and directly control each battery module with the connected network. Many problems of network complexity 4 are based on the isolated serial-connected network connection, although the mining has determined the problem of multiple battery modules reference electricity, and there is no - occupy multiple identification codes (10) sparse 〇nNmnber, ID The need, but multiple batteries - and the existence of a large number of data at the same time, still cause the data transmission time is too long, the management system is slow. 5. The increase in the amount of power directly in the 'direct connection to the network, or the number of battery modules on the connected network is also increasing #, indirectly causing a surge in the amount of data on the Qingqing, per-time data The transmission time is therefore increased, which makes the decision time slow. The result of the data transmission delay 'may result in time error in the decision data, and the correctness of the decision is seriously affected. It can be seen that there are still many shortcomings in the above-mentioned conventional techniques, which are not the design of goodness, but need to be improved. , - Ben Lai Zuo, in view of the shortcomings of the above-mentioned system technology, * thinking to improve and innovate,
