10 +== Improvements ==
11 +
12 +* Unibat: preventing the reset of the HVBPITS and HVBPITR signals if the device shutdown was caused by the insulation fault
13 +
14 +== Fixes ==
15 +
16 +* Unibat: charge current limit protection is disabled in charge mode only when the "Use continuous charge current limit" flag is set
17 +* Unibat: discharge current limit protection is enabled regardless of whether the battery is in discharge or charge mode

22 +
23 +== Improvements ==
24 +
25 +* setting and clearing the "Voltage unbalance" errors without delays
26 +* new CAN bus speed is not applied until the device is rebooted
27 +* logging the following new parameters: "UnibatState", "UnibatOperationalModeState", "Keyrun", "ChargeOn"
28 +* Unibat: ability to shutdown the battery if its SOC is too low (see the "External equipment - Unibat vehicle - Diagnostic parameters" section)
29 +* Unibat: change the resolution of parameters CC and DC from 0.01 to 0.1 Ah/bit
30 +* Unibat: do not turn on the amber lamp if the actual battery SOC is equal to the configured maximum operational SOC
31 +
32 +== Fixes ==
33 +
34 +* resolving the problem of completing the initialization process before the power switch voltage stabilizes

40 +== Features ==
41 +
42 +* support for the Trolleybat vehicle (see the "External equipment - Trolleybat vehicle" section)
43 +
44 +== Improvements ==
45 +
46 +* checking the continuous charge current limit only if the "Use continuous charge current limit" flag is set in the "External equipment - Unibat vehicle - General parameters" section
47 +* Unibat: transition to charging mode according to the condition EESCD=7
48 +
49 +== Fixes ==
50 +
51 +* resolving the problem of completing the initialization process before the power switch voltage stabilizes
52 +* Unibat: prevent the "Charge request" and "Discharge request" signals from being reset if the Unibat vehicle goes offline (the signals are controlled in the Unibat state machine)

65 +
66 +== Features ==
67 +
68 +* new profile section with global battery status, which includes total charge and energy counters, total operating time, contactor opening count, etc. (see the "Profile" tab in the Unified monitor)
69 +* new total charge counters (plus and minus)
70 +
71 +== Improvements ==
72 +
73 +* Unibat: new flag to set the custom value (=3) for the EESCD signal (see the "External equipment - Unibat vehicle - General parameters" section)
74 +* Unibat: new bit field to ignore internal errors that cause battery shutdown (see the "External equipment - Unibat vehicle - General parameters" section)
75 +* Unibat: sending a new packet containing the continuous charge current limit
76 +
77 +== Fixes ==
78 +
79 +* optimization of the logging process, minimizing the time to open the next log file if the current one is full
80 +* resolving the stability problem when the SD card is full
81 +* Unibat: prevent sending module online statuses if the power down condition is met
82 +* Unibat: small fixes

87 +
88 +== Improvements ==
89 +
90 +* turning on power switches with a delay of 1 second after reaching the supply voltage of 9V
91 +* Unibat: new flag that allows to hide the insulation testing status when repeating measurements (see the "External equipment - Unibat vehicle" section)
92 +* expansion of the list of parameters that are reset to default values when the device is powered on while holding the button on the board. The following parameters are affected: all CAN1 (ext) settings; all CAN2 (int) settings; all CAN3 (BMS) settings; all RS-485-1 (Modbus) settings; LAN settings: IP mode, IP address, Netmask, Gateway address
93 +
94 +== Fixes ==
95 +
96 +* resolving the issue of false warnings indicating that the battery current exceeds the current limits (affects Unibat vehicle)
97 +* Unibat: changes that make it so that the output period is responsible for only 4 messages, not for all messages (see the "External equipment - Unibat vehicle" section)
98 +* Unibat: resolving the issue of TP messages not being sent if the transport is already transmitting something at the time of the request
99 +* corrections of typos in parameter descriptions
