Dropping into Low Gear to slow down


Best Answer Tom_NC_1 , 29 April 2017 - 01:15 PM

My Neighbour has a CMAX Energi as well. He said the dealership told him to drop into low gear when slowing down to a stop light/sign or slowed traffic in order to more efficiently recapture energy.

Wouldn't that be harder on the transmission??

 

(Note: I am not meaning dropping it at 30 miles an hour to slow it down from that speed but around 10-12 mph

 

Dropping to L is a signal to the computer to increase regen and this will slow the car very efficiently. You can go to L at any speed without any adverse effects on the transmission. Shifting to L does not shift to a different gear like it would in a conventional transmission.

If using the brakes instead of shifting to L, you have to be careful not press the brake peddle to hard or the actual brake pads engage to slow down rather than just regen. Using L ensures that only regen is used to slow down. 

 

The downside to relying on shifting to L to slow down is that it an cause the engine to come on if the HVB is still full because there is no place to store regen energy. A second byproduct of using L at higher speeds is that the high current flow back to can cause quicker heat build up in the HVB. Excess heat buildup in the HVB in hot climates can contribute to loss of capacity in the HVB.

It you use a Scangauge and are only seeing a maximum of 50 amps, check the formula and change the multiplication factor from 1 to 2 to get a correct reading. (Mth : 000200010000)

The display will be a maximum of about 110 amps during braking. I used to try and get 100% on brake score but I'm less hard on myself these days and am happy to get in the high 90s.

That was it. My MTH entry was wrong. Thanks for the tip!

 I also find that I only use it when a light changes suddenly at speed and I know I am going to get into the brakes or to slow down of coming off an exit ramp at speed.
