Non esiste una definizione assoluta di SOH: è una stima basata su una serie di valori (accettazione di carica, resistenza interna, tensione e autoscarica, per esempio) a cui a volte si attribuiscono pesi soggettivi.
Per un utente di auto elettrica, quello che conta di più è di solito la capacità della batteria di erogare energia e quindi ottenere l’autonomia desiderata. Sapere l’SOH è utile in particolare quando si acquista un’auto elettrica usata e si vuole avere un’idea delle condizioni della sua batteria, che è uno dei componenti più costosi.
Maggiori informazioni sono su Wikipedia e Electropedia.
Non ho ancora provato sulla mia iOn, ma intanto pubblico qui le istruzioni che ho trovato:
- SpeakEV;
- hobDrive (iscriversi al Beta channel, installare la versione beta, configurarla per i-MiEV or simile, andare a Screens - Settings - VehicleSettings - ECUsettings e impostare Vehicle ECU type = "Mitsubishi iMiEV";
- My iMiEV.

http://evpositive.com/battery-history.html: If you multiply the Ah capacity (eg 35 Ah) by the average Voltage (eg 320 Volts for the PHEV battery), you get 11.2 kWh (P=V * I for those who are electricians). This figure in kWh you are probably more familiar with from your household power bill or Chademo fast charge display. So Ah gives the true battery capacity that you can directly compare to other EV as it only depends on the battery age and usage, and does not depend on your driving style, hills, passenger and luggage loads, tyre pressure, heater or air conditioner usage etc. Battery degradation is important as it does diminish the range that you can achieve in your EV.
The expectation is about 80% of original capacity after 10 years. This is the "PMC" (Percentage of Manufacturer's Capacity) percentage displayed in our App EvBatMon.
after a full charge you will get the best distance if you drive your EV straight away. This is because the battery loses some of its energy (something like about 5% in the first 24 hours) just sitting in your garage. This is the case with all Lithium batteries, and using the battery straight after a full charge is also good for the battery. Some EV (eg Tesla) even allow you to stop charging at 80% etc so the battery does not sit fully charged for extended periods.
