| 11 | |||
| 12 | * new parameter setting a delay before measuring battery current during precharge (see the "Cells - Discharging control" section) | ||
| 13 | * new counter of retry attempts showing the communication problems with BMS Logic devices (see the "Logic/Cell - Overview" section) | ||
| 14 | * 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) | ||
| 15 | * 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 | ||

| 17 | == Fixes == | ||
| 18 | |||
| 19 | * 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) | ||
| 20 | * increased number of retries when sending commands to BMS Logic devices, which reduces the number of false offline event detections | ||

| 30 | == Fixes == | ||
| 31 | |||
| 32 | * 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) | ||

| 60 | == Features == | ||
| 61 | |||
| 62 | * new parameter for setting the condition for starting balancing: automatically (regardless of the command) or on the balancing request (see the "Cells - Cell balancing" section) | ||
| 63 | * new option to start balancing if the cell voltage exceeds the "Voltage for forced balancing" value (see the "Cells - Cell balancing" section) | ||
| 64 | * new assignment "Balancing request" for the discrete inputs (see the "Signals - Input signals" section) | ||
| 65 | * new Max-Min algorithm for calculating the final battery SOC in the "Cells - SOC estimation" section | ||

| 68 | * new assignment "Close External 1" for the discrete inputs (see the "Signals - Input signals" section) | ||
| 69 | * new assignment "External 1" for the discrete outputs and relays (see the "Signals - Output signals" section). The "External 1" output is directly controlled by the "Close External 1" command. | ||
| 70 | * new "Precharge error" flag that is set when precharging cannot be completed | ||
| 71 | * new flags in the "Protections - Undervoltage protection" and "Protections - Overvoltage protection" sections which allow using the calculated open circuit cell voltage instead of the actual voltage to detect the "Undervoltage" and "Overvoltage" errors, respectively | ||
| 72 | * ability to check the "Ready to charge" and "Ready to discharge" signals to control the charging and discharging contactors (see the "Cells - Charging control" and "Cells - Discharging control" sections) | ||
