Source: www.evexpert.eu

The battery management system (BMS) is commonly referred to as a battery nanny or a battery housekeeper, which is mainly for the intelligent management and maintenance of each battery (cell), preventing the battery from overcharging, over-discharging and overcurrent, and prolonging the use of the battery Life, monitor battery status (voltage, current, temperature, etc.), functions include thermal management, balance control, fault diagnosis, charge management, participation in energy recovery, etc. Basically, electronic parameters are used to identify changes in physical and chemical reactions. Therefore, it is very important to equip the battery pack with a BMS protection system.

BMS Construction

The design of the BMS corresponds to a large extent to the design of the battery. It consists of a battery monitoring integrated circuit (BMIC), a cell management controller (CMC) and a battery management controller (BMC).

The BMIC monitors the individual battery cells and must be able to quickly - in a matter of microseconds - inform the CMC of the situation so that the CMC or BMC is able to react and, if necessary, correct an unfavourable situation. In order to prevent temperature leaks, the BMIC needs to notice immediately the battery cell that is overheating and send this information further on as quickly as possible. The BMC must decide how serious the situation is, how to proceed, and the overheated cell must be shut down if necessary. And all of this must happen in the blink of an eye.

The accuracy of the measurement and the ability to respond to adverse conditions depend primarily on the frequency of communication from the BMIC to the CMC and BMC, the more often they communicate, the greater the chance that they will successfully resolve a situation that could be risky. However, it is not at all easy to design an effective communication network in an electric car due to electrical noise.

Of course, before correcting the BMS tries to prevent any unfavorable situation, so apart from the BMIC, CMC and BMC modules it also consists of circuits that balance the energy loads of different cells, in this way all cells work more or less the same and do not tend to cause problems. 

Depending on how complicated the electric car is, several intelligent microcontrollers may be added to monitor and control various specific tasks. Each BMS must be able to monitor not only the battery but also itself and it must be able to determine if alarms or prompts are real and not fake.

Basic functions of BMS

  1. Discharge and charging control
  2. Determination of the current state of charge (State of Charge)
  3. Determination of State of Health
  4. Charge balancing
  5. Recording and communication

BMS development

In order for each BMS system to be able to perform its functions correctly, several puzzles need to be overcome for its development. The first is the Battery State Estimation. This is a value that is important both for the driver and for the system itself and its proper management.

The second is Battery Cell Charge Balancing. There are passive and active methods, as well as various active balancing topologies that need to be properly designed to optimize BMS properties.

Battery State Estimation

The state of charge of the battery is absolutely essential information for the driver. Moreover, the use of the battery could be extended if it was possible to obtain an accurate value. 

Battery cell charge balancing

Battery cells are differences can be in internal resistance, level of degradation, capacity, ambient temperature, and many more. These inevitable differences between cells can cause many problems, and overall capacity can be dramatically reduced. This imbalance then causes the individual cells to be over-discharged or over-charged, which is dangerous for the battery pack as a whole, and thus charge balancing between the individual cells is of paramount importance to maintain performance and extend battery lifespan.

     Industrial computer originated in 1984. Early industrial computers were used in the manufacturing process of factories, the control and monitoring of instruments and machinery, and then entered the field of life gradually, and were specialized for different industries. Whether it is the surge in demand for robots in an automated society, the explosion of 5G micro-base stations due to the Russia-Ukraine war, or the mysterious military weapons, they are all areas that industrial computers can touch.

 

     IPCs are different from general consumer and commercial personal computers, which are roughly unified in specifications, so they are mass-produced. Due to the highly customized nature of industrial computers, customers are mostly equipment users or system integrators with technical capabilities, and have certain special needs for product specifications, designs, and services. IPC manufacturers not only need to have technical capabilities, but also have a considerable understanding of the customer's industry to meet the different design needs of customers in different industries. They are customized products and are service-oriented.

 

  • IPC Industrial characteristics:
  1. High product quality and stability requirements
        Industrial computers are mostly used in the industry, and often must be operated in special environments, or operated for a long time. For example, production line automation equipment, data switches in telecommunication equipment rooms, monitoring equipment, enterprise network security servers, navigation systems. It must operate continuously and stably for a long time without interruption, otherwise, it could cause significant losses. Therefore, the stability requirements of the computer system used are particularly strict.
  2. Have a certain technical threshold
        Most industrial computers have industry-specific specifications and are not standardized products, so there are compatibility issues between systems. At the same time, the product must meet the customer's special requirements for the working environment, such as temperature (humidity), waterproof (dust) performance, voltage stabilization system, and uninterruptible power system requirements for special design and adjustment. Therefore, manufacturers must have considerable R&D, production, testing, marketing, and system integration capabilities, have a certain technical threshold, and need to have strong technical capabilities to provide technical consultation before customers and maintenance services after sales.
  3. Long-term supply and strict quality management
        Due to high system stability requirements, IPC usually adopt mature technologies in the market to reduce the probability of failure. The replacement frequency of IPC is less than that of general consumer electronics products, and the life cycle is also longer. Therefore, IPC manufacturers must be able to provide long-term maintenance services and supply capabilities within the product life cycle. At the same time, a long product cycle means that the system may have to run continuously for many years.  Quality control must also be very strict to maintain operate long-term stability of customer systems. For IPC manufacturers, it is also a test of technology and quality control.
  4. Wide range of application fields, many changes in specifications and characteristics
        In addition to being used in the manufacturing industry, IPC have been used in a variety of industries and life surroundings, such as finance, medical care, aerospace, telecommunication networks and life automation, with a wide range of applications. Since it is not a standardized product, the specification changes are very diverse, and it also tests practitioners' familiarity with different customer industries and their ability to design and manufacture different specifications.

 

    In the future, IPC must also provide more complete after-sales services and a more consumer-friendly environment. Because the industrial computer is an intelligent carrier, it should not wait until a problem occurs to provide services, but should be an intelligent service mechanism. Future products should embed integrated data processing capabilities, combined with cloud service capabilities, to become a proactive and valuable service provider, not just a simple after-sales service.
