I don't know that they always err on the generous side; I know ICE cars tend to show ideal conditions, but somehow we get a lot more mpg from our hybrid than the manufacturers say. Think it may be our style of driving and the fact we don't do a daily commute at high speed with intervals of traffic jams, although I do find it very economic in traffic. |
this is why I am interested in how much people *actually* spend rather than theoretical figures. It might well be better than reported.
There is a figure banded around regarding how much tumble driers cost to run - this figure is used to prove a dehumidifier is a more efficient way to dry clothes - yet when I measured what both my tumble drier actually used, and what my dehumidifier used, the figures were way off. The dehumidifier was a lot worse, and the tumble drier a lot better. Turns out, regarding tumble driers, that although the figure was reported widely, it came from only one source and that source made incorrect assumptions - like tumbling for much longer than I do, etc..
Manufacturers theorectal figures are usually inaccurate as they are based on assumptions and averages.
So when people say ' it costs me this much to run my Ev, the manufacturer tells me so' I tend to faze out... I find it quite surprising that people dont know the actual figures. |

Battery claims
The following link is to the complete list of claims I have been compiling.
https://martindavidwalker.blogspot.com/2024/09/battery-claims.html
The new claims in the last week are as follows.
October 2nd 2024, Altech deploy solid state sodium chloride battery for testing
The batteries are claimed to have a 15 year lifetime. Cheap sodium batteries are a key factor in renewable energy storage.

September 29th 2024, Hyundai promises cheaper LFP battery production
The article alludes to the much touted $100 per kwh figure that was meant to mark production price parity with ICE cars, and puts the 2023 cost at $139. But both BYD and CATL have talked about prices halving in 2024 which would put current costs at $70.
The Hyundai process which eliminates a production step is a promise of another cost reduction.

September 26th 2024, General Motors to produce CATLs 6c charging battery in China
This is a life line for general motors whose sales have collapsed in China. News on this battery that can fully charge in 10 minutes has been around since June, but now we hear it will be in cars in 2025.

September 25th 2024, cheap iron chloride cathodes
The revolutionary material, iron chloride (FeCl3), costs a mere 1-2% of typical cathode materials and can store the same amount of electricity.
The cost of their whole battery system is 30-40% of current LIBs as no Nickel or Cobalt is used.
The technology is pitched as being less than 5 years from commercialisation.

September 23rd 20202, Lechanche launch long life battery with niobium based anode
The claim is a 10,000 life cycle battery suitable for heavy duty mining applications. |
