Yaris MY20

Hybrid Assistant now supports the new Yaris MY20

 

A new dress

 Hybrid Assistant has a new icon, a minimal design inspired by the old one.

But not only that: Hybrid Reporter is now integrated into the main app and is accessible from the settings menu.

You can open it only when the car is stopped, for obvious safety reasons.

8 years of battery usage

My Yaris is approaching its 8th birthday and has just passed the 80.000 km mark.

In the last 4 years she has lost her internal garage parking place to her bigger sister Auris, so she also has passed 4 winters and 4 summers under the stars, with no particular care so it's time for an HV check.

Here is a full discharge/recharge cycle chart from Hybrid Reporter:
All blocks discharge uniformly, none of them behave significantly different from the others.

We have further confirm from the Delta chart, where we see that voltage difference is always well under 0.2V, and just above 0.1 at the lower SOC levels.

According to this article, battery is still at near full capacity.

These charts suggest little Yaris has many more years of travel in front of her wheels.

OBDLink 4.7.1 firmware update

Some users have reported issues with the latest firmware update of the OBDLink adapter.

Please do not update until further testing.

Hybrid Assistant has always been a free product.
From time to time, we received inquiries from people who were asking if they can contribute to its development somehow.
We always refused to charge any money for it.
Now this has changed: if you, as a satisfied Hybrid Assistant user, think this app has contributed somewhat to improve your driving and reduce your emissions, think about making a donation, the amount you think it's worth, to an hospital of your own choosing.
Thank you.

Hyundai/Kia Powertrain Analysis

User An-IONIQ of the hybridlife.org French forum, has written a deep analysis of the Hyundai/Kia powertrain, using Hybrid Assistant as a measurement tool.
Here is the original work, while an Italian translation, with additional comments courtesy of team member Gabriele, is available on Hybrid Synergy Forum

Hybrid Assistant usage in high school

We just received an interesting email, from France, about an unexpected usage of Hybrid Assistant: thank you Antony.

My name is Anthony Berçon, I’m a technical trainer in a french high school specialized in car repairing. I’d like to share my experience about Hybrid Assistant, and my way to use it.

First of all, it’s a powerful and compact app to get data about hybrid powertrain. Usually we use a professional tool like a Sun PDL 5500 to collect and export data, to be analyzed with MS Excel.

HA makes the same thing and its data collection has enough precision for our usage.

At this moment, with my students, I'm working on the regenerative brake, and the relationship between SOC battery, regenerative brake and battery temperature. With the help of the HA staff, it was easy to export data and make some charts to explain that relationship. 

My next step will be to create exercises about potential energy, kinetic energy, negative acceleration and SOC. I’ll use it to help students understand how Toyota hybrid works.

Here are some examples of HA usage in my teaching:

Graph 1 explains the relationship between vehicle speed and regenerative/mechanic brake system.

Graph 2 shows partitioning of braking torque between the 2 braking systems.

The next 2 graphs show battery temperature being influenced by regenerative brake.
