10 +== Improvements ==
11 +
12 +* support for 32-bit BMS Logic serial numbers
13 +* increasing the stability of the BMS Wi-Fi v2 driver
14 +
15 +== Fixes ==
16 +
17 +* resolving the problem of charge, discharge, and charge/discharge contactors closing when the "Precharge request" signal is set
18 +* synchronization of the precharge procedure with the charge/discharge algorithms, so that precharge is stopped if charging and discharging are prohibited
19 +* resolving the stability problem when the SD card is full
20 +* small fixes in current maps

33 +
34 +== Improvements ==
35 +
36 +* new flags for generating the "Ready to charge" and "Ready to discharge" signals using the actual cell voltage instead of the calculated open circuit voltage (see the "Cells - Charging control" and "Cells - Discharging control" sections)

45 +
46 +== Improvements ==
47 +
48 +* new flags that force the precharge process to finish if the battery current is negative (in case the battery will be charging) or positive (in case the battery will be discharging); see the "Cells - Charging control" and "Cells - Discharging control" sections
49 +* 30 second delay when remounting SD card after detecting mount error
50 +* new flag to prevent the "HYG offline" error from occurring if the "Charger connected" signal is set (see the "External equipment - HYG Class I-III truck" section)
51 +* new flag that controls whether to wait for confirmation from the HYG truck or not, to allow the battery to be charged (see the "External equipment - HYG Class I-III truck" section)

57 +== Improvements ==
58 +
59 +* new parameter setting a delay before measuring battery current during precharge (see the "Cells - Discharging control" section)
60 +* new counter of retry attempts showing the communication problems with BMS Logic devices (see the "Logic/Cell - Overview" section)
61 +* new flag to keep the precharging contactor closed until the precharging process is finished (in this case the "Precharge error" will not occur; see the "Cells - Discharging control" section)
62 +* new flags that force only positive and negative currents to be used to determine open circuit voltages to control the "Ready to charge" and "Ready to discharge" signals respectively
63 +
64 +== Fixes ==
65 +
66 +* resolving the issue of not being able to send log files to a remove FTP server due to a change in the file name format (v1.70.0)
67 +* increased number of retries when sending commands to BMS Logic devices, which reduces the number of false offline event detections

79 +* resolving the issue of ill-considered reduction of the battery SOC level when the cell voltage is close to the level corresponding to SOC=0% (due to the flow of a large discharge current leading to the high voltage drop on the cells)
