Much as humans need a heart to distribute energy throughout our bodies, EVs need a heart to transfer energy from their batteries to their motors. This “heart” of an EV is called a power module, and it’s responsible for driving the vehicle’s propulsion unit as efficiently as possible. Considering the critical importance of power modules,… Read more »

MIT-led study suggests route to improving solid-state batteries
Replacing a liquid electrolyte with a solid electrolyte could offer major advantages for both safety and energy storage capacity, but so far, attempts to develop a practical solid-state cell have run into major obstacles. Liquid electrolytes can be flammable, and are also prone to the formation of dendrites -thin, fingerlike projections of metal that build… Read more »
The technical reasons Tesla would limit supercharging speed, and other practical charging considerations
Recently, a bit of a kerfuffle kicked up when a Tesla Model S owner noticed that the maximum charge rate for his car on the Supercharger network had suddenly been cut from 120 kW down to 90 kW, apparently the result of too many fast charge cycles. Tesla’s explanation was, essentially, that many things can… Read more »
Mitsubishi delivers 635 Outlander PHEVs to Ukranian police

This is the second time MMC has supplied vehicles under the Green Investment Scheme – in 2011, it delivered 507 i‐MiEVs to the government of Estonia. Since its launch… Read more »
EV tech explained: What are the limiting factors of an EV’s regenerative braking force?
In many EVs, regenerative braking is limited by the manufacturer to a modest level, and usually offers little or no ability for the driver to adjust it (aside from the few cases in which regen is made proportional to the initial movement of the brake pedal). Is tepid regen braking the result of some sort… Read more »
Motorcyle maker Energica unveils fast charging station in Italy’s Dolomites

Why is Tesla limiting the charging rate at Superchargers?
What’s this? Tesla is limiting my Supercharging rate, saying I’ve been fast-charging too often? It’s an outrage! I signed up for unlimited Supercharging forever! Splutter…argh..ack! ack! [falls backward, clutching at chest] Not so fast. Calm down and let Tesla explain. Yes, the vehicle software will limit the Supercharging rate for vehicles that have racked up… Read more »
Mitsubishi Electric develops ultra-compact SiC inverter for hybrids
Mitsubishi Electric has developed a working model of an ultra-compact silicon carbide (SiC) inverter for hybrid vehicles. The company believes it to be the world’s smallest SiC of its type, with a volume of only 5 liters. Mitsubishi also claims that the new inverter offers the world’s highest power density for two-motor hybrids: 86 kVA/L,… Read more »
