Learn MoreWhen your main battery is low, it no longer charges your 12V battery, so that doesn''t mean your 12 battery is bad. Thus, you must charge your main battery up to see if your 12V battery recovers. When your 12V battery is bad, it would usually throw numerous errors then the car dies even though you have plenty of range left in your main …
Learn MoreDiagnosis and estimation of battery constraints involves particular cell and total cells voltage, current, temperature and impedance.

Learn MoreWithout proper control over the operating conditions of a battery system, the system is susceptible to failures resulting in explosion, fire, expulsion of toxic gasses, or other negative impacts to humans and the environment. ... it was found that short-circuiting of high-voltage power lines initiated the fire that spread to about 25% of the ...
Learn MoreA common problem we often inquire about with hybrid vehicles is a fault code in the Battery Management System (BMS) stating: the precharging time of the high voltage on-board electrical system is too lon g. Fault codes such as 0C7800 or P0C78 may be current in BMS ECU, but the exact fault code varies between manufacturers. Some of …
Learn MoreAs with most things in engineering, arbitrarily increasing the pack voltage isn''t unequivocally a good thing, and that''s even without invoking a reductio ad absurdum argument (e.g. if 1 kV is better than 100 V, then 10 kV is better than 1 kV, etc.). Still, there are some benefits to increasing the pack voltage, and the most obvious is that less cross …

Learn MoreI recently had the "Service High Voltage Charging System" message on my 2013 Gen1 Volt come up. After taking it to the dealer they told me that the issue was caused by faults in the HPCM2 and BECM modules. They reprogrammed and recalibrated the modules and kept the car overnight to let it sit so they could re-check in the morning.
