For example, a difference of just +/-1 % from ideal (average) value of the voltage will create SOC mistake of around 40 %! each production party and each battery has slight differences from average parameters.

Obviously, some data thou is not cleaned correctly! Additionally, these are not statistic data (as, for example, data regarding the temperature of the battery), but much more important data – SOC is, possibly, the most important data in whole IBS system!ĭeleting of these data (everything, what is connected with a profile of the battery and SOC) is critically important! Determination of SOC is a very complicated task.

Let’s connect INPA and check the data of all available registers.
#BMW ISTA P VOLTAGE PROBLEM REGISTRATION#
Here, Launch confirms, that the registration of battery is completed. But I got a hint, on what base is Launch built (didn’t spending my time to investigate it). Developers of Launch have not taken into account this nuance (or – even haven’t noticed it). INPA (obviously, Launch uses INPA script) shows +1 Ah against the true value. Here we see one inaccuracy: actually, the capacity of the registered battery is 90 Ah (according to ISTA D). Exception: current SOC is not availble!Īnd now – let’s start coding of battery replacement! These data correspond with INPA and ISTA D. At first let’s check, does the Launch correctly reads status data of the battery. SOH is positive (value – correct), but data counters of energetical balance have gone to the “second circle” SOC data regularly incorrect (unavailable) the energetical balance of the day – with incorrect values.Īs we see, for the car, which is more than 10+ years old, no battery was registered.Ĭonnect Launch.

Here, IBS data of car before registering the battery: Task – to understand, does Launch performs at the same level (at least in the level of available data) as ISTA D. Today’s experiment – a battery of E60 will be registered with Launch, then data will be checked with INPA. Part of these products are actually using BMW databases and scripts, but the interface is more modern and more simple for the user.

In addition – very accessible.īut there are persons, who choose alternative products, developed by the third side, for example, Carly, Pro Tools, Launch, etc. In my work, I use only tools, created by professionals of BMW AG – for now, they are the most powerful of available ones.
