| 12 | * increasing the smoothness of changing the current limit values | ||
| 13 | * ability to exclude errors from being saved in the error journal (see the "Service - Errors journal" section) | ||
| 14 | * extension of the CANopen dictionary to provide additional information for the BMS Display (device serial number, battery serial number, battery address, Wi-Fi and LAN addresses, SOH, capacity, etc.) | ||

7.2 | 26 | |
| 27 | * support for the HYG Global CAN protocol version 2 (June 13, 2024) | ||
| 28 | * calculation of regenerated energy | ||
| 29 | * calculation of new lifetime parameters: average temperature, average charge/discharge currents, etc. See the counters in the "Service - Counters" section | ||
| 30 | * new "Need acknowledge" warning signal that is set when a new record is created in the errors journal. The signal can be cleared in the "Service - Errors journal" section | ||
| 31 | * new parameter for setting the condition for starting balancing: automatically (regardless of the command) or on the balancing request (see the "Control - Cell balancing" section) | ||
| 32 | * new option to start balancing if the cell voltage exceeds the "Voltage for forced balancing" value (see the "Control - Cell balancing" section) | ||
| 33 | * new Max-Min algorithm for calculating the final battery SOC in the "Control - SOC estimation" section | ||
| 34 | * new flags in the "Protections - Undervoltage" and "Protections - Overvoltage" sections which allow using the calculated open circuit cell voltage instead of the actual voltage to detect the "Undervoltage" and "Overvoltage" errors, respectively | ||
| 35 | * ability to check the "Ready to charge" and "Ready to discharge" signals to control the charging and discharging contactors (see the "Control - Charge" and "Control - Discharge" sections) | ||
| 36 | * improved control of the precharging contactor, which can precharge capacitive load using multiple attempts and detect high power dissipated in the precharge resistor (see the "Control - Precharge" section) | ||
| 37 | * ability to select errors that the device saves in the errors journal (see the "Service - Errors journal" section) | ||
| 38 | |||
| 39 | == Improvements == | ||
| 40 | |||
| 41 | * ability to configure and monitor the device via the CAN1 (ext) bus | ||
| 42 | * placing the device input signals to the "Battery" section and adding raw discrete inputs to the "Signals" section | ||
| 43 | |||
| 44 | == Fixes == | ||
| 45 | |||
| 46 | * using the calculated open circuit voltage to set/clear the "Ready to charge" and "Ready to discharge" signals | ||

1.1 | 52 | == Improvements == |
| 53 | |||
| 54 | * new balancing strategy that attempts to keep the temperature of BMS Logic devices below a set value by discharging cells with higher voltages first than others (see the "Control - Cell balancing" section) | ||
| 55 | |||
| 56 | == Fixes == | ||
| 57 | |||
| 58 | * resolving the possible problem of saving device parameters | ||
| 59 | * resolving the problem of writing the device's working time to a non-volatile memory very often | ||

2.1 | 65 | == Features == |
| 66 | |||
| 67 | * new algorithms in the Charging/Discharging controller that allow to control the Charging/Discharging contactor independently from the Charging and Discharging signals (see the "Control - Charge/Discharge" section). The new "Independent" algorithms are preferred in the battery systems with one contactor. | ||
| 68 | * selection of errors that cause reset of contactor control signals (see the "Control - Main contactor", "Control - Charge", "Control - Discharge", "Control - Charge/Discharge", "Control - Discharge (AUX)", "Control - Heater", "Control - Cooler", "Protections - General error", "Control - Charging status", "Control - Discharging status" sections) | ||
| 69 | * new "Current limit error" which is set if the battery current exceeds the charging or discharging current limits (see the "Protections - Charge current limit" and "Protections - Discharge current limit" sections) | ||
| 70 | * new parameter to select the method of calculating the battery voltage: sum the cell voltages or use the measured voltage before contactors (see the "Control - Common settings" section) | ||
| 71 | * clearing the Discharging (AUX) signal if the cell voltage is too low (see the "Control - Discharge (AUX)" section) | ||
| 72 | * new assignment "Close External 1" for the discrete inputs (see the "Signals - Input discrete signals - Assignments" section) | ||
| 73 | * new assignment "External 1" for the discrete outputs and power switches (see the "Signals - Output discrete signals - Assignments" and "Signals - Power switches - Assignments" sections). The "External 1" output is directly controlled by the "Close External 1" command. | ||

| 77 | * rearrangements in the settings sections, which are made to simplify the setup process |
