1. Nzira dzekumuka
Kana yatanga kuvhurwa, pane nzira nhatu dzekumuka (zvigadzirwa zvemangwana hazvizode activation):
- Button activation inomuka;
- Kuchaja activation kumuka;
- Kumutsa bhatani reBluetooth.
Kune inotevera magetsi-on, kune nzira nhanhatu dzekumuka:
- Button activation inomuka;
- Kuchaja activation kumuka (apo magetsi ekuisa charger anosvika 2V akakwira kupfuura bhatiri voltage);
- 485 kutaurirana activation kumuka;
- KUNOGONA kutaurirana activation kumuka;
- Discharge activation inomuka (ikozvino ≥ 2A);
- Key activation inomuka.
2. BMS Sleep Mode
TheBMSinopinda yakaderera-simba modhi (yakasarudzika nguva ndeye 3600 masekonzi) kana pasina kutaurirana, pasina mutero / kuburitsa ikozvino, uye pasina chiratidzo chekumuka. Munguva yekurara, kuchaja uye kuburitsa MOSFETs inoramba yakabatana kunze kwekunge bhatiri riri pasi pemagetsi raonekwa, panguva iyo maMOSFET anozodambura. Kana iyo BMS ikaona masaini ekutaurirana kana kuchaja / kuburitsa mafungu (≥2A, uye yekuchaja activation, magetsi ekuisa charger anofanirwa kunge ari 2V yakakwirira kupfuura bhatiri voltage, kana paine chiratidzo chekumuka), inokurumidza kupindura uye pinda mukumuka-kumuka kushanda mamiriro.
3. SOC Calibration Strategy
Iyo chaiyo yakazara huwandu hwebhatiri uye xxAH yakaiswa kuburikidza nekombuta inotambira. Munguva yekuchaja, kana sero voltage inosvika pakukwirira kwepamusoro kukosha uye paine kuchaja ikozvino, iyo SOC ichave yakarongedzerwa ku100%. (Panguva yekuburitsa, nekuda kwekukanganisa kweSOC kuverenga, SOC inogona kunge isiri 0% kunyangwe kana undervoltage alarm mamiriro akazadzikiswa. Ziva: Iyo zano rekumanikidza SOC kuenda zero mushure mekudzivirira kwesero overdischarge (undervoltage) inogona kugadzirwa.)
4. Mhosva Kubata Strategy
Zvikanganiso zvinoiswa muzvikamu zviviri. Iyo BMS inobata mazinga akasiyana ezvikanganiso zvakasiyana:
- Level 1: Zvikanganiso zvidiki, iyo BMS inongorira chete.
- Level 2: Kukanganisa kwakanyanya, maaramu eBMS uye anocheka switch yeMOS.
Kune anotevera Level 2 kukanganisa, switch yeMOS haina kugurwa: yakawandisa voltage musiyano alarm, yakawandisa tembiricha musiyano alarm, yakakwira SOC alarm, uye yakaderera SOC alarm.
5. Kuenzanisa Kudzora
Passive balancing inoshandiswa. TheBMS inodzora kubuda kwemasero emagetsi epamusorokuburikidza resistors, dissipating simba sezvo kupisa. Iko kuenzanisa ikozvino 30mA. Kuenzanisa kunotangwa kana zvese zvinotevera zvinosangana:
- Panguva yekuchaja;
- Iyo balancing activation voltage inosvika (yakagadziriswa kuburikidza nekombuta inotambira); Voltage musiyano pakati pemasero> 50mV (50mV ndiyo yakasarudzika kukosha, inogadziriswa kuburikidza nekombuta inotambira).
- Default activation voltage ye lithium iron phosphate: 3.2V;
- Default activation voltage ye ternary lithium: 3.8V;
- Default activation voltage ye lithium titanate: 2.4V;
6. SOC Estimation
Iyo BMS inofungidzira iyo SOC ichishandisa nzira yekuverenga coulomb, ichiunganidza kuchaji kana kubuda kuti ifungidzire kukosha kwebhatiri reSOC.
SOC Estimation Kanganiso:
| Kururama | SOC Range |
|---|---|
| ≤ 10% | 0% < SOC < 100% |
7. Voltage, Current, uye Temperature Accuracy
| Function | Kururama | Unit |
|---|---|---|
| Cell Voltage | ≤ 15% | mV |
| Total Voltage | ≤ 1% | V |
| Current | ≤ 3%FSR | A |
| Tembiricha | ≤ 2 | °C |
8. Kushandisa Simba
- Kuzvidyira ikozvino kwebhodhi rehardware paunenge uchishanda: <500µA;
- Kuzvishandisa ikozvino kwebhodhi software paunenge uchishanda: <35mA (pasina kutaurirana kwekunze: <25mA);
- Kuzvishandisa ikozvino muhope mode: <800µA.
9. Soft Switch uye Key Switch
- Iyo yekusarudzika logic yeiyo soft switch function ndeye inverse logic; inogona kugadzirwa kune yakanaka logic.
- Basa rekutanga rekiyi switch ndeyekuita iyo BMS; mamwe mabasa epfungwa anogona kugadzirwa.
