240 +* Enable – a flag to start calculation of the charge current limit;
241 +* Maximum charging current – a maximum allowable value of the charge current (under normal conditions):
242 +* Limit charging current by the battery SOC and temperature – a flag to enable correction of maximum allowable charging current Kcs depending on SOC and temperature;
243 +* Limit charging current by the contactor temperature – a flag to enable correction of maximum allowable charging current Kcc depending on the contactor temperature;
244 +* Limit charging current by the maximum cell voltage - a flag to enable correction of maximum allowable charging current Kcv depending on maximum cell voltage;
245 +* Limit charging current by the maximum cell temperature - a flag to enable correction of maximum allowable charging current Kc depending on maximum cell voltage.
246 +
247 +Value of the charge current limit at given SOC, temperature, contactors temperature and maximum cell voltage is calculated as follows:

249 +Charging current limit = Maximum charging current × Kcs × Kcc × Kcv
