9 +
10 +== Features ==
11 +
12 +* 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)
13 +* forwarding CLI and bootloader CAN messages from CAN EXT interface to CAN INT interface and back
14 +* new parameter for setting the type of network to which the BMS GSM communication module connects (see the "Connectivity - Cellular" section)
15 +* 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)
16 +* 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)
17 +* ability to select the battery module errors that cause the battery critical error (see the "Protections - Critical error" section)
18 +* 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)
19 +
20 +== Improvements ==
21 +
22 +* dynamic calculation of data transfer schedule for optimal communication with a large number of battery modules
23 +* 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)
24 +* 30 second delay when remounting SD card after detecting mount error
25 +* saving the number of joined modules in log files
26 +
27 +== Fixes ==
28 +
29 +* resolving the issue of saving some battery module signals in log files

32 +
33 +[[BMS_Main_X2_v2.7.0.srec>>FileManager.BMS_Main_X2_v2\.7\.0\.srec]]
34 +
35 +== Features ==
36 +
37 +* 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
38 +* 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
39 +* new Max-Min algorithm for calculating the final battery SOC in the "Control - Calculation" section
40 +* 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)
41 +* ability to exclude errors from being saved in the error journal (see the "Service - Errors journal" section)
42 +* ability to restart the device according to a specified schedule at the moment when the battery system is preparing to charge
43 +* 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)
44 +* new internal signal "Coolant pump" that can be assigned to a relay or discrete output (for signal settings, see the "Control - Coolant pump" section)
45 +* new flags indicating the readiness of battery modules to join for charging and discharging (see the "Modules" section)
46 +* 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)
47 +* initial support for Pylontech inverters
48 +* 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.)
49 +
50 +== Improvements ==
51 +
52 +* 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)
53 +* placing the device input signals to the "Battery" section and adding raw discrete inputs to the "Signals" section
54 +
55 +== Fixes ==
56 +
57 +* resolving the issue of ignoring the minimum number of battery modules allowed to join located in the "Control - Discharge" section
58 +* 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
59 +* small internal fixes
