177 +The BMS Main 2.x board has 4 discrete outputs. For each discrete output, its purpose and inversion requirement are specified. The following discrete output assignment options are supported:
178 +
179 +* No output;
180 +* Low SOC;
181 +* Hgh battery charge current;
182 +* Cooler;
183 +* Heater;
184 +* Allow charging;
185 +* Precharging;
186 +* Acknowledgement of power down;
187 +* Power up.
188 +
189 +If the "Low SOC" assignment is selected, the output indicates the low battery charge level (see section Low SOC signal).
190 +
191 +If the "High battery charge current" assignment is selected, the output indicates that the charging current exceeds the predefined value (see section High charging current signal).
192 +
193 +If the "Cooler" assignment is selected, the output indicates the overheating of the battery (see section Temperature protection).
194 +
195 +If the "Heater" assignment is selected, the output indicates the low battery temperature signal (see section Temperature protection).
196 +
197 +If the "Allow charging" assignment is selected, the output is used to give the charger the allowance to charge the battery (see section Charge control).
198 +
199 +If the "Precharging" assignment is selected, the output is used to charge the capacitive load (see section Discharge control).
200 +
201 +If the "Acknowledgement of power down" assignment is selected, the output is used to acknowledge power down of the BMS. Acknowledgement is outputted when the charge and discharge relays have been opened on power down request (see sections Charge control and Discharge control).
202 +
203 +If the "Power up" assignment is selected, the output is used to indicate the power status of BMS (see section Power down control).
204 +
205 +
206 +The BMS Main 2.x board has 4 solid-state relays (#1 and #2 of them are bipolar, and the #3 and #4 are unipolar). For each relay, its purpose and inversion requirement are specified. The following relay assignment options are supported:
207 +
208 +* No relay;
209 +* Charging;
210 +* Discharging;
211 +* Allow charging;
212 +* Cooler;
213 +* Heater;
214 +* Precharging;
215 +* Balancing series 1;
216 +* Balancing series 2;
217 +* Discharging (AUX);
218 +* Main contactor;
219 +* Power up.
220 +
221 +If the "Charging" assignment is selected, the relay is used to charge the battery (see section Charge control).
222 +
223 +If the "Discharging" assignment is selected, the relay is used to connect battery to the load (see section Discharge control).
224 +
225 +If the "Allow charging" assignment is selected, the relay is used to give the charger an allowance to charge the battery (see section Charge control).
226 +
227 +If the "Cooler" assignment is selected, the relay receives a signal indicating overheating of the battery (see section Temperature protection) or the signal "Cooler" (see section Cooler control).
228 +
229 +If the "Heater" assignment is selected, a low battery temperature signal is outputted to the relay (see section Temperature protection) or a signal "Heater" (see section Heater control).
230 +
231 +If the "Precharging" assignment is selected, the relay is used to charge the capacitive load (see section Discharge control).
232 +
233 +If the "Balancing series 1" assignment is selected, the relay is used to connect a balancing resistor to the cell series 1 (see section Series balancing).
234 +
235 +If the "Balancing series 2" assignment is selected, the relay is used to connect a balancing resistor to the cell series 2 (see section Series balancing).
236 +
237 +If the "Discharging (AUX)" assignment is selected, the relay is used to power external equipment (see section Powering external equipment).
238 +
239 +If the "Main contactor" assignment is selected, the relay is used to close the main contactor in the common (minus) power bus.
240 +
241 +If the "Power up" assignment is selected, the relay is used to close the contactor in the BMS Main power bus.
