Veel "utiltairder" kan een voertuig niet zijn natuurlijk:

De reusachtige Komatsu dump-truck rijdt in Zwitserland dagelijks vele malen op en neer tussen een berg (waar grondstofen geworden worden) en een cementfabriek.

Men heeft het ding voorzien van een nogal forse batterijpack (nikkel-Mangaan kobalt-technologie,je ziet,het moet niet altijd Lithium-technologie zijn)

Huh? Dat zijn Li-NMC batterijen natuurlijk is daar Lithium(-technologie) bij voor de werking. Li wordt dikwijls weggelaten in de afkorting. NMC is het kathodemateriaal.

Lithium Nickel Manganese Cobalt Oxide (LiNiMnCoO2 or NMC)

One of the most successful Li-ion systems is a cathode combination of nickel-manganese-cobalt (NMC). Similar to Li-manganese, these systems can be tailored to serve as Energy Cells or Power Cells. For example, NMC in an 18650 cell for moderate load condition has a capacity of about 2,800mAh and can deliver 4A to 5A; NMC in the same cell optimized for specific power has a capacity of only about 2,000mAh but delivers a continuous discharge current of 20A. A silicon-based anode will go to 4,000mAh and higher but at reduced loading capability and shorter cycle life. Silicon added to graphite has the drawback that the anode grows and shrinks with charge and discharge, making the cell mechanically unstable.

The secret of NMC lies in combining nickel and manganese. An analogy of this is table salt in which the main ingredients, sodium and chloride, are toxic on their own but mixing them serves as seasoning salt and food preserver. Nickel is known for its high specific energy but poor stability; manganese has the benefit of forming a spinel structure to achieve low internal resistance but offers a low specific energy. Combining the metals enhances each other strengths.

NMC is the battery of choice for power tools, e-bikes and other electric powertrains. The cathode combination is typically one-third nickel, one-third manganese and one-third cobalt, also known as 1-1-1. This offers a unique blend that also lowers the raw material cost due to reduced cobalt content. Another successful combination is NCM with 5 parts nickel, 3 parts cobalt and 2 parts manganese (5-3-2). Other combinations using various amounts of cathode materials are possible.

Lithium Nickel Manganese Cobalt Oxide also lithium-mananese-cobalt-oxide (LiNiMnCo, NMC, NCM), Li[NiMnCo]O2 based Cathode & Graphite based Anode, is the newest generation Li-Ion rechargeable battery for high power applications, such as EV car, E-scooter and E-bike.

The NMC cells compromise between high current rate and high capacity rate. Compared with LiCoO2 series Li-Ion cell, the NMC cells provide higher energy density with lower cost, long cycle life (>[email protected], IEC standrad).
NMC cell has 3.6 +/- 0.5V nominal working voltage and shall be cut-off power at 4.15-4.20V per cell during charging.

Uw "kennis" van Lithium-ion-batterijen weten we nu ook....

Maar we zien hoe e-drive ook binnendringt in de meest zware domeinen,deze waar de ruige dieselaandrijving nog steeds heerst!

Denk je, de diesel zal enkel nog dienen als generator om de stroom te leveren, de aandrijving zal dus 100% electrisch zijn!
