HV Check of a 208.000 km battery

Here is the HV Check of a 7 years old RAV4, with 208.000 km under its wheels.

The deltaV of the cells is always between 0.1 and 0.2 V.
It looks like the battery is still well balanced.

According to the owner, the only visible difference between the brand new battery, is the visible gap between the moment when the charging begins and when the SOC actually starts to increase.


Support for old Android versions

Google is phasing out old Android versions: new updates published on the store must support new SDKs and deprecate older ones.

People with old Android versions, like 4.3, might not be able to run Hybrid Assistant anymore, if updated from the Play Store.

For those still using old Android versions, here is the last APK that still supports them.

You might have to remove the current version before installing this one.

Do not update from the Play Store after installing.

The APK is provided as-is, with no support and no future updates: if you want the latest Hybrid Assistant version, get a new Android device.


New permission request for Android 12

The new version of Hybrid Assistant is compliant with Android 12, that changes Bluetooth permissions management.

A new permission request will appear at the first run; you must select "Allow" to connect to the Bluetooth OBD device.


10 Years of battery usage

 My Yaris is now 10 years old: it's time to have a look at its battery:

It's still looking good, with delta between battery blocks under 0.1V most of the time, just a little worse than the 8th year check.

Car usage is mostly urban, so plenty of EV battery depletions, and forced charges, because of slow moving traffic. Open air parking at night also.

On a side note, the 12V battery is still the original one.
I've never had a car with a service battery lasting more than 5 years: probably the periodic CTEK treatment had some benefical effect on that.


We're back online

Google has acknowledged our app is using Location Permissions according to the Developer Program Policy and Hybrid Assistant is available again on the Play Store at the following link:


Google Policy woes...

Hybrid Assistant has been removed from the Play Store, due to an allegedly policy violation.
Google says that the Location Permission used by Hybrid Assistant is not compliant with the Developer Program Policy.
Hybrid Assistant uses Location information to provide telemetry data for Hybrid Reporter charts and stats, and this is an integral part of the app purpose.
Location data is always stored locally to the device, and it's not shared with anyone unless the user explicitly exports the produced reports.
We're going to write to Google Support to sort this out and we're confident Hybrid Assistant will be available on the Play Store again soon...


Android 11 compliance

Google is about to enforce Android 11 compliance for apps on the Play Store.

Last year we merged Hybrid Reporter into Hybrid Assistant to prepare for this compliancy requirement.

The update we just published fulfills the requirement that an app is not allowed to write to the filesystem at will.

This means that the _hybridassistant directory, where datafiles are stored, will be migrated to a private directory: this will be totally transparent to the average user, who will see a "Migrating" message on the first run only.
Reports will still be accessible from the Hybrid Reporter menu as always.
If you are an "advanced" user, willing to consult the Hybrid Assistant database directly, you'll find an "Export" button in the Hybrid Reporter Database Maintenance screen that will allow to copy the database on Goggle Drive, for example.
