Regenerative Braking Rate Comparison

[Zulu67MP]

Hi All,

I've not spotted this twist amongst other threads, so here goes...

Which provides a greater rate of charge equivalence, Level 5 for x seconds, or Level 1 for 5x seconds?

Or is the charge rate curve linear across the B range (always found it curious that you can have a linear curve!)

Does anyone know, or more to the point has anyone noticed, if there's any useful difference that can help save on running costs by few fractions of a monetary unit?

The above didn't seem to make it to the daily email circulation, so this is just to try again. Any responses?

(If I'm posting incorrectly, will someone please let me know how? Ta.)

There's nothing wrong with your question, I'd assume the silence is because no one has tried to map it.

You'd need an ODBII dongle and specialised software to capture that information.

Some members have stated that they get better mileage by keeping the car in B0 and gaining the benefit of freewheeling. This makes sense because there are losses when regenerating, and it eliminates unnecessary slow downs. And, if you anticipate your stops, you still get the benefit of regenerative braking unless you stomp on the pedal and use the physical brakes.

I prefer to use higher levels (B4 or B5) when driving in traffic because it is easier to deal with the stop/start nature of the traffic around me.

Thanks Andy,

I drive at B0 when braking's unlikely and at higher levels similar to yourself in traffic. My right foot appreciates the Adaptive Cruise Control, though it seems to be limited to around B2, so doesn't include 'cruising' at B0. (This may simply be a safety feature to simulate engine braking, especially for former ICE/automatic drivers who might otherwise just run into each other thinking the car will slow down sooner.)
This then requires conscious disengagement when inclines call for B0 for fuel-saving, which at least helps keep me awake and aware!

I guess you're right about measuring for comparative B output levels... I was just wondering if someone might already have the answer. More an academic question than one with any savings potential, I suspect .
