Answering tough demands

Depending on mechanical design of the battery pack, it might be beneficial using the solution with concept of multiple BMS modules, which are not located directly at each “S” (serial) cell, but inside the battery pack (or inside the charger for balancing charger variant) and concentrically dissipating the waste heat. Depending on the required balancing currents (charging / balancing time), these types are produced in variants of 100mA and 1000mA.

BMS8i and BMS16i types provide balancing during the charge as well as the “permanent” balancing methods.
As a standard, MGM COMPRO intelligent systems feature modularity to care for almost unlimited number of cells, unique connectivity and diagnostics, safety and reliability, various communication protocols (automotive and aerospace) including the possibility of customisation.

New horizons of safety

The essential feature is unrivaled reliability thanks to having all the crucial components doubled. Moreover, these types provide you with the most advanced hardware real-time self-checking, which makes MGM COMPRO Battery Management systems one of the most reliable on the market.

Born to be Airborne

Both MGM COMPRO BMS8i and 16i fit perfectly for aircraft applications. Besides many other key features, MGM COMPRO also offers option of airborne logic of use.

High balancing currents, fast charging

BMS-2 | BMS-256 systems balance extremely high currents of up to 10A! This brings significant advantages over competing systems. One basic difference is the speed at which the cells are balanced, which has a fundamental impact on the overall charging process. For LiFePo4-type batteries, where balancing occurs in approximately the last 5 % of the charging process, the balancing speed (the size of the balancing current) is of central importance. Balancing systems with low currents greatly extend the period needed to fully charge these cells (causing a lag), multiple times over in some cases.

Advanced monitoring, unique care

BMS-2 | BMS-256 systems represent a precise form of protection with advanced diagnostics for all cells in the battery system. All of the critical parameters of every cell are monitored and communicated to a supervisory system (CAN bus) with real time logging of the most important parameters. Data can later be reviewed to identify specific incidents involving an individual cell. This is an invaluable tool for diagnosing and troubleshooting various faults and failures in chargers, incorrect handling of cells or the presence of a defective cell with subsequent application of a claim.

BMS-2 | BMS-256 systems eliminate the impact of the internal resistance in cells and power conductors. They feature absolutely unique way to ensure temperature monitoring of the power components (absolute elimination of potential for overheating and destruction is thus ensured). The system enables communication with supervisory systems and collaboration with HBC series controllers.

Simply put, it’s an excellent system, chock full of innovative technology and algorithms. It is capable of balancing high currents, providing unique care and extending the life of batteries in the system. These all represent important financial returns.

Passive Balancing Type

Modular solution, which is very beneficial for some types of battery pack mechanical designs. The biggest advantage is direct placement of very small and lightweight modules at each “S” (serial) cell inside the battery pack. This type of BMS offers various balancing methods according to the concrete needs of the final application. The system can balance when charging as well as permanently, which is the optimal solution for battery packs, where the weight plays the most important role and at the same time balancing is realised through lower currents. In these cases, the system cares for having the battery being balanced throughout the time.

Active Airborne Type

The most advanced type of PBT design BMS is represented by AAT variant, where balancing is actively realised through transferring the charge from the cells with higher level of charge to the cells with lower level of charge. The main advantage is higher balancing current with lower heating. The natural thing, like with all the MGM COMPRO Battery Management Systems, is having various communication channel possibilities, parameter settings adjustable through PC user interface, firmware updates, data diagnostics and much more.
