Structure of battery?

[ruffieuxh]

Hi,
I wonder if anyone got his hand on a chart how the MME battery is structured in terms of

• kWh of brick protection
• kWh of lower (usable) reserve
• kWh of upper reserve (difference between 100% on display and real BMS 100%)

Thanks

I don't know what the exact amounts are, but I believe the buffer on the lower end is much higher than that on the upper reserve, since it is much more dangerous to have batteries fully depleted then to have them topped off.

91 kWh usable out of 98.8 kWh rated. That leaves about an 8% buffer, roughly equally split between the top and bottom. Maybe 3.5% top buffer and 4.0% bottom buffer. So the difference between displayed and real will be up to about 3-4%.

Thanks Lee,
Yeah, that was my gestimation too. But do you know it for sure? Is there an upper buffer and is the lower buffer usable (i.e. will the MME stop when the display shows 0m range)?

I seem to remember someone on here reported that they were able to drive 4 miles once everything read '0'. Small sample size and all.....
