![]() ![]() They are designed to simply connect across the terminals of the battery, and also have built in circuit protection in case you wire them the wrong way. Out of the box, both the Oricom unit and the Autohil unit are very similar. The other thing that can be great about a battery monitor is connecting one where your battery may not be easily accessible as it can save time trying to get access to it with a multi-meter. If it is outside the acceptable ranges, that could help indicate an issue with the alternator rather than the battery. ![]() If you are having issues with your vehicle, the monitor can check the charging voltage to make sure it is normal. The voltage is useful as a measure of charge of the battery – as the battery depletes, the voltage drops, and once it gets below a certain level (usually 12V or below), then the battery is considered discharged, and may no longer start your vehicle. It allows you to see how the voltage drops with usage, see the current condition of the battery, understand the cranking voltage, and also measure the charging voltage of the battery. But what exactly do they do?Ī Bluetooth Battery monitor allows you to track the voltage of your battery via your smartphone. Both these devices are designed to connect to your battery and monitor the performance. The two battery monitors that I’ve reviewed are the Oricom Battery Sense Monitor, and the Autohil ABM2. The small device on the battery negative terminal, a 24/7 voltage and coulomb data logger, provides that info.I recently got sent a few battery monitors, and thought I’d install them to see what the fuss is all about. I have noticed that even that can be modified if the system thinks the 12V battery has been depleted more than normal. I think EE is correct in pointing out that a charge during driving is not reliable, the time schedule is better. And, instead of a daily 20 min charge we get six a day for the first 60 hours parked then back to daily. It just "dithers" around, see graph below, noting that "charging" requires around 14.6 V. Since the Campaign 196 update that was carried out on all examples during 2019, it doesn't charge while driving anymore - but it doesn't drain the battery either. In short, it used to charge for the first 30 min of driving (for the day) as it still does for the first 30 min of (traction battery) charging. There are also posts somewhere from me regarding the apparent lack of charging while driving. More elastic voltage excursions can be a sign of a damaged 12V battery but there's nothing untoward here, just thought I'd check.Ī couple of us have done that boot experiment, myself at #349 in this thread. I will take voltage measurements with my Fluke when time permits, but what I have seen so far is impressive (and a long time coming if I might add).Īny other reports with this new software would be appreciated for those who have had it installed, but from what I have seen so far, I give it a huge thumbs up I observed this 3 times now (only been 1 day since update). The frequency of the 3.5- 4 hour documented ~ 15 minute recharge periods are now reduced in half ~ 1.75 to 2 hours, again observed using the yellow light. I first noticed the Hyundai emblem glow yellow on 3 sequential short drives after shutdown ranging from 1km to 10km. The vehicle charges the 12V battery ~10 minutes after shutdown- for a 15 minute period. The updated software# (Canada) is this: C00D111 - VCULDC Control Logic Improvement. I do not run a 12V monitor, so no graphs to supply, however those that do run 3rd party software can report more accurate findings. After applying a second "VCULDC" software update during my first annual service (yesterday), I will report some very interesting and positive observations.
