High-voltage batteries are indispensable for the electrification and decarbonisation of vehicles worldwide, but the specific energy and energy density limitations of current battery technology bring challenges to the forefront when optimising different kinds of EVs. Take heavy-duty commercial EVs, for example.
from the battery (within battery design parameters) to be achieved. If a project is using “off peak” charging of the batteries, great care should be taken to ensure that the additional charging load imposed by the battery will not jeopardise the integrity of the main supply fuse and take the demand a
In the pursuit of lower maintenance costs and emissions, battery recycling is likely to be important for future generations of heavy-duty commercial EV fleets, although predictions vary as to when the first major recycling efforts for lithium-ion packs will begin.
ront of the battery case which remains energised during a power outage. More complex systems (requiring DNO permissions and some protective electrical engineering work5) such as the Tesla Powerwall 26, can provide mains power in the event of a power cut through their “gateway”
Electric vehicles are heavy because batteries are heavy. There’s just no way around it. The lithium-ion packs in EVs are the state of the art in modern battery technology and can store far more energy in a given amount of space compared to other rechargeable battery types such as nickel-cadmium.
The high volume and maintenance costs associated with electrifying a fleet of heavy commercial vehicles have certain impacts on how the battery management systems (BMSs) for such systems should be designed. For instance, end-users typically demand very high lifetime and ruggedness in their battery packs.
