Driven by the increasing adoption of installed capacity and renewable energy generation, the distributed BMS is becoming more widespread. Additionally, the popularity of distributed BMS is growing due to its simplicity of installation and high reliability. As a leading energy solutions provider, MOKOEnergy adheres to the spirit of innovation and progress and has introduced the latest wireless distributed battery management system that aligns with future trends. The aim is to offer smarter and more convenient solutions for electric vehicles, energy storage systems, industrial applications, and more. Before delving into MOKOEnergy’s wireless distributed BMS, let’s first understand the traditional wired and wireless distributed BMS offerings provided by MOKOEnergy.
Traditional Wired and Wireless Distributed Battery Management Systems
MOKOEnergy provides customers with distributed battery management systems that are categorized into traditional wired and the newly introduced wireless. Distributed BMS is one type of BMS topology. A traditional wired BMS monitors and manages the condition of the cells in a battery pack through a wired connection. Although this wired system has worked well in the past, with the development of electric vehicles, energy storage systems, and industries, traditional wired BMSs are facing some limitations, such as complicated wiring and high maintenance costs. As a result, MOKOEnergy is committed to stepping out of its comfort zone and introducing a more up-to-date and challenging wireless distributed BMS. Let’s take a closer look at the features of wired and wireless distributed systems and find the technology that fits your industry.
Traditional Wired Distributed BMS
MOKOEnergy’s conventional wired distributed BMS is a proven and reliable solution that has already been used in practice by companies in many fields with excellent feedback. In this system, the battery modules or cells are connected using wired communication, and the data is transmitted via cable to a central control unit. A conventional wired BMS ensures that battery parameters such as voltage, current, temperature, and charge state are accurately monitored and managed to ensure optimal battery performance and safety.
The highlight of MOKOEnergy’s Traditional Wired Distributed BMS:
Energy balance: MOKOEnergy’s distributed BMS achieves dynamic balance within the battery pack, ensuring that the charging and discharging state of each battery cell remains consistent, and improving the efficiency and life of the entire battery pack.
High reliability: MOKOEnergy’s distributed BMS disperses the battery management function among multiple modules or battery cells so that even if one module fails, the others can continue to work. This redundancy improves the reliability of the whole system and reduces the risk of the whole system crashing due to a single point of failure.
Data Transmission Security: In a wired distributed BMS system, each module or unit of the battery pack is connected by cable to a central control unit or master controller. Data is transmitted over these wired connections and can be digital signals, analog signals, or serial communication signals. Therefore, there is no need to design robust security measures to block network threats like wireless BMS systems, thus ensuring a certain amount of data security.
Compact and reliable MCU: For measurement modules embedded in one or more units, the MCU of the distributed battery management system should be compact, reliable, and preferably with a CAN transceiver controller. Therefore, MOKOEnergy chose the S9So8DZ60 with functions of the analog-to-digital converter, SPI, and CAN bus as the main single-chip microcomputer of the measurement module, which meets the functional battery management system requirements and is easy to further expand.
Wireless Distributed Battery Management System
MOKOEnergy’s wireless distributed BMS is a pioneering innovation in battery management technology, representing a leap forward in the era of progress. This system leverages advanced wireless communication protocols, such as Bluetooth, WiFi, and Radio Frequency, to connect battery modules and transmit data to a central monitoring unit, eliminating the need for physical wires and cables. Compared to traditional wired distributed BMS, the wireless distributed BMS offers numerous unique advantages, including reduced installation complexity, increased flexibility, and enhanced fault detection capabilities. Let’s take a closer look at these advantages:
The highlight of MOKOEnergy’s Wireless Distributed BMS:
Data immediateness: Since MOKOEnergy’s wireless distributed BMS has data collection and processing functions in each battery cell or module, it can monitor the battery status and performance of each battery cell or module in real-time, which makes fault diagnosis more timely and can prevent potential problems and take corresponding measures.
Enhanced reliability: The wireless distributed BMS distributes the battery management function among multiple modules. When one module fails, the other modules can continue to work. Through wireless communication, such as BLE, WiFi, or RF, the system will prompt the fault in time to repair it as soon as possible to ensure normal operation.
Low power consumption and expanded lifespan: MOKOEnergy’s wireless distributed battery management system replaces the wired serial interface between the CMU and the BMU with a low-power wireless transceiver, helping to extend battery life.
Higher current and voltage: MOKOEnergy’s wireless distributed BMS uses an open-loop current sensor TKC200F with a measurement range between -200 and 200a and linearity within 1%, and uses LV25-P to detect battery voltage, which measures voltage signals up to 500V. Higher currents and voltages enable this wireless distributed battery management system to support high-power applications and large-scale energy storage systems.
Data Management: The network of MOKOEnergy’s wireless distributed BMS consists of a master controller connected to the battery pack MCU and eight wireless devices. Each wireless device has an accompanying battery monitor and balance, which measures the voltage and temperature of the battery cells in the BMS and reports the SOC and SOH data to the BMS MCU through the master node controller.
What’s more, let’s take a closer look at the most popular wireless Bluetooth-based distributed BMS. MOKOEnergy’s developed wireless distributed BMS embeds a Bluetooth communication module, integrating essential wireless communication components like a BLE communication chip and antenna into a single unit, making it a leading innovation. With this product, we have proven our competitiveness in seizing the rapidly growing market for wireless distributed BMS.
Furthermore, in the application process of new energy vehicles, to achieve wireless transmission and reception of electric vehicle battery data and other functionalities, wireless distributed BMS must be equipped with dozens of components such as BLE circuits, BLE communication chips, and antennas. In the case of previously released wireless distributed BMS, these components had to be individually connected to the PCB one by one. As a result, the BMS production process required a significant amount of time and posed too much development burden in expanding the product lineup. On the contrary, MOKOEnergy first applied a wireless Bluetooth communication module developed using high precision, high-density, multi-layer board technology to wireless products. The wireless Bluetooth communication module consists of a four-layer board densely integrating dozens of wireless communication components. This structure enabled the company to develop a unique wireless BMS that facilitates easier installation of battery management system modules.
