Kingsdon BMS battery management control system architecture

What is battery management system (BMS)?

In many high-power applications, such as Electric Vehicles (EVs) and Hybrid Electric Vehicles (HEVs), Battery Management System (BMS) is needed to ensure battery safety and power delivery. BMS performs cell balancing (CB), State of Charge (SoC) estimation, monitoring, State of Health (SOH) estimation, and protective operation.

What is the generalized architecture of proposed battery management system (BMS)?

The generalized architecture of Proposed BMS design is shown in Fig. 9 (a)- (b). In proposed design, battery management systems (BMS) employ LTC6812 analogue front end (AFE) IC to monitor and regulate battery cell conditions. AFE has cell voltage sensor and external balancing circuitry MOSFET driving connections.

Why is a battery management system important?

It is also the responsibility of the BMS to provide an accurate state-of-charge (SOC) and state-of-health (SOH) estimate to ensure an informative and safe user experience over the lifetime of the battery. Designing a proper BMS is critical not only from a safety point of view, but also for customer satisfaction.

What is a BMS used for?

BMSs are used in various applications, including Electric Vehicles (EVs), smartphones, renewable energy storage systems, and other devices powered by rechargeable batteries. The building unit of the battery system is called the battery cell. The battery cells are connected in series and in parallel to compose the battery module.

What is a battery management system?

The battery management system is typically an electronic circuit that monitors and controls the battery including cell voltage, temperature, input or output current of the battery, and the battery voltage. It also controls the connection of the battery to the DC link, or the high voltage link.

What is a cloud-based battery management system (BMS)?

As summarised in Table 1, a cloud-based BMS offers several improvements and advantages and opens multiple new horizons to monitor and control battery packs compared to a conventional BMS in different dimensions. Based on the discussions presented in the sections so far, the next section will introduce the perspective IBMS.
