A series of cells must be equivalent: they must have the same number of cells and the same capacity. 677 677 678 678 Since the series of cells can operate at different loads, they must be balanced. For this, the BMS Main 3 provides two signals to power switches: “Balancing series 1” and “Balancing series 2”, as well as a combined algorithm that considers both the voltage of each series and the charge that these series gave load. The “Balancing series 1” and “Balancing series 2” signals are used to connect high-power balancing resistors in parallel with cell series 1 and 2. 679 679 ... ... @@ -690,17 +690,17 @@ 690 690 691 691 In this section: 692 692 693 -* Enable – a flag to enable series balancing; 694 -* Number of Logics in a series; 695 -* Minimum series voltage to start balancing, V; 696 -* Balancing threshold, V; 697 -* Coulomb threshold – the difference of the charges Qthr, given by a series of cells, above which balancing to be started, Ah; 698 -* Period – a period to reset of charge counters for each series (to avoid accumulation of error), second; 699 -* Do not sum series voltages – a flag to disable the summing of series voltages. 3694 +* **Enable **– a flag to enable series balancing; 695 +* **Number of Logics in a series**; 696 +* **Minimum series voltage to start balancing**, V; 697 +* **Balancing threshold**, V; 698 +* **Coulomb threshold** – the difference of the charges Qthr, given by a series of cells, above which balancing to be started, Ah; 699 +* **Period **– a period to reset of charge counters for each series (to avoid accumulation of error), second; 700 +* **Do not sum series voltages** – a flag to disable the summing of series voltages. 700 700 701 701 === Power down === 702 702 703 -The BMS Main 3 device can shut down itself if the battery voltage is low or the battery is idle for a long time. 704 +The BMS Main 3 / BMS Main 2R device can shut down itself if the battery voltage is low or the battery is idle for a long time. 704 704 705 705 Shutting down the battery system is performed according to the following conditions: 706 706 ... ... @@ -715,7 +715,7 @@ 715 715 716 716 In this section: 717 717 718 -* Minimum voltage to power down – a minimum voltage level of the battery below which the BMS commands to shut down the battery, V; 719 +* **Minimum voltage to power down** – a minimum voltage level of the battery below which the BMS commands to shut down the battery, V; 719 719 * Idle time to power down – a time of battery inactivity after which the battery is shut down, minute; 720 720 * Wait the "Power up/down request" is cleared (on startup) – a flag to enable delay for clearing the “Power up/down request” signal while starting the BMS. 721 721 * Power down if KEYRUN and CHARGE_ON are cleared – a flag to power down the device if KEYRUN and CHARGE_ON signals are cleared;
