HV Battery care " parking in the red

[notch]

I have a battery cycle method that I use on my commute that I would like to share with the forum. I cycle the battery once a week.


Morning 2 RED BAR START
On the way to work I use a charging drive technique
a mixture of coasting, light brakes and of course engine braking on off-ramps with a light pedal pressure on the brake pedal and I can reach a full peak charge 89% by the time I pull into work. I also prefer to have the rear window have-way down on either side to create drawing air to maximize cooling - I am certain the battery is getting warm (it just got a full charge

Afternoon commute 8 full bars
With the car fully charged driving on heavy traffic I am able to use liberal throttle and remain in ev mode to speeds up to 38 at speed I use the typical pulse and glide going warp steal with a variation of speed between 73-67 mph (less people will hate you and milage will average 55.5)
Once off the free way the car will be somewhere around 4 blue bars- drive normal with the A/C at max cold last few blocks milk electric mode and you will reach 3 bars- Pull up into the drive way placing the car in nuetral and apply the parking break at you gather your things (a/c still blasting) turn off prius at two bars...

The point is a consistent charge and discharge cycle will provide your battery with the longest life and when you use this method the battery stays in the green much longer... I cycle my HV batt once a week to insure it visits both ends of the batteries reachable volts

After all that I have learned from this site I thought I would share this with you guys

What sort of fuel economy do you typically get on these trips with your battery management strategy?

hmmm

hmmm, never thought of that

I was under the impression that keeping the NiMH battery within a narrowly confined operating limit helped prolong its life

+1. The car is programmed to keep HV Battery charge at about 60% on average.

My Prius came with an ECU that takes care of the HV battery for me.

I don't have to worry about such things as full peak charge, the typical pulse and glide, going warp steal, rolling windows up and down or cycling my battery.

I can just enjoy driving this great car.

NiMH batteries don't have a "memory" like the old mercury batteries. Deep cycles can actually be harmful. That's why the Prius works so hard to keep it between 40% and 80%. I paid good money to have the car worry about the battery.
