If from a frien, i dont know if its LEV50 or LEV50N but its from a i-Miev.
ScottyDont that its true, but the I-miev has an output power of 60kW, same that the phev in EV mode so in this case that is not a desing factor.
I think the cells are well isolated. They dont touch the case walls so only way to transfer heat is trough natural convection (fan stopped) by the interal air.
This morning i did a trip with 5ºC ambient temperature, speed about 80kmh and a final consumption of 16.1 kWh (low power demand). The...
Here in Spain its forbidden to sell cars without AC for example. In summer (up to 40ºC) its usual to see the AC compressor working for the battery. But also in winter long trips (300km) at 3ºC ambient sometimes it kicks in for a while as the pack heats in the charge and discharge hysteresis...
I think there is no heating, only have seen the fan working above 35ºC while driving and 30ºC at CHAdeMO. But my battery has never been below 0ºC. Anyone has seen the fan working at low temperatures? The most symple whay to do it for me will be to use the evaporator as a radiator (heat pump).
I still think its not cause by balancing. Sometimes the Ah increases 1-2 after some ours parked, and that must be software related, so if you loose some Ah maybe its also software.
Interesting, but is normal for a lithium battery to reduce the voltage a bit after charge. You can test it with a spare cell without bms. For me going from 3.958V to 3.952V is not due to balancing but tempertarure changes and the resting of the cell, is just 6mV. Passive balacing when the...
Balancingshould only take place at full charge. If you park the car 1 month it does not discharge as fast as what is described in this post. Is not a energy loose problem, is a energy calculation problem.
I rotated my original Toyos at 40.000km and now with 65.000km they have similar wear and i think they will last other 10.000-20.000km. Front wear is higher so rotation is a must. High presures and smoth driving also help a lot.
Are you sure that the regen reduction is caused by battery temperature and not the state of charge? I've never noticed regen reduction even at ambient temperature of 40ºC, the battery cooling system works fine and keeps it under 37ºC. Try it again with the app to see the temperature.
Even...
The engine at partial load has lower volumetric efficiency than in high load situation, so generator braking the engine will increase fuel efficiency thats for sure. And my experience is the same as Trex, lower SOC better fuel economy.
Today i tested to press 4WD button while driving, this was the result:
Normal Mode:
4WD
Each time i pressed it the front motor delivered more power and rear motor less. For me it has no much sense, any idea?
I think that even it is not a 4x4, with some software change performance from...
Is not a power or torque problem, just traction. A center lock diff does not split torque or power, just equalize RPM. The problem with taking out the boat with rear axle having traction would disappear if 4wd button makes both axles turn at the same RPM, the front wheels will spin, but rear...
Hi. I think my BMU is having some strange behavior.
1-When drive the car just after charging it, the battery use to be at 103-106% of charge (using EVbatmon). After driving 2 or 3 km the cells voltage is around 4.02 volts, but there is zero regen until i get under 100% of SOC. This is a bit...
