9 +
10 +== Improvements ==
11 +
12 +* new CLI command "find-log" which finds a log file containing a specified timestamp
13 +* ability to acknowledge battery module errors via CLI (see the "Service - Errors journal" section) and Modbus protocol
14 +
15 +== Fixes ==

22 +
23 +== Features ==
24 +
25 +* new flags that allow to interrupt (shorten) the module balancing stage if all battery modules are already joined (see the "Control - Charge", "Control - Discharge", "Control - Charge/Discharge" sections)
26 +* forwarding CLI and bootloader CAN messages from CAN EXT interface to CAN INT interface and back
27 +* new parameter for setting the type of network to which the BMS GSM communication module connects (see the "Connectivity - Cellular" section)
28 +* new flag that controls whether to use open circuit voltage or actual voltage when determining the voltage unbalance error (see the "Protections - Voltage unbalance (in any state)" section)
29 +* new regulator that maintains battery current limiting to ensure that actual module currents do not exceed their current limits (see the "Control - Charge", "Control - Discharge", "Control - Charge/Discharge" sections)
30 +* ability to select the battery module errors that cause the battery critical error (see the "Protections - Critical error" section)
31 +* ability to update the device serial number from the service account if the number is reset to the default value for some reason (see the "Service" section)
32 +
33 +== Improvements ==
34 +
35 +* dynamic calculation of data transfer schedule for optimal communication with a large number of battery modules
36 +* ability to complete device initialization after the set timeout has expired and the minimum number of modules has been detected (see the "Control - Initialization" section)
37 +* 30 second delay when remounting SD card after detecting mount error
38 +* saving the number of joined modules in log files
39 +
40 +== Fixes ==
41 +
42 +* resolving the issue of saving some battery module signals in log files

45 +
46 +[[BMS_Main_X2_v2.7.0.srec>>FileManager.BMS_Main_X2_v2\.7\.0\.srec]]
47 +
48 +== Features ==
49 +
50 +* new algorithm 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" algorithm is preferred in the battery systems with one contactor
51 +* 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
52 +* new Max-Min algorithm for calculating the final battery SOC in the "Control - Calculation" section
53 +* 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)
54 +* ability to exclude errors from being saved in the error journal (see the "Service - Errors journal" section)
55 +* ability to restart the device according to a specified schedule at the moment when the battery system is preparing to charge
56 +* new error "High contactor temperature" that can be used to open the specified contactor to prevent it from overheating (see the "Protections - High contactor temperature" section)
57 +* new internal signal "Coolant pump" that can be assigned to a relay or discrete output (for signal settings, see the "Control - Coolant pump" section)
58 +* new flags indicating the readiness of battery modules to join for charging and discharging (see the "Modules" section)
59 +* new flag to set the "Voltage unbalance" errors for battery modules that are not ready to charge or discharge (see the "Protections - Voltage unbalance (in any state)" section)
60 +* initial support for Pylontech inverters
61 +* 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.)
62 +
63 +== Improvements ==
64 +
65 +* ability to finish device initialization even if the number of battery modules found is less than the number of modules enabled (see the "Control - Modules" section)
66 +* placing the device input signals to the "Battery" section and adding raw discrete inputs to the "Signals" section
67 +
68 +== Fixes ==
69 +
70 +* resolving the issue of ignoring the minimum number of battery modules allowed to join located in the "Control - Discharge" section
71 +* resolving the issue of joining battery modules the number of which must be greater than or equal to the minimum value specified in the settings
72 +* small internal fixes
