Wärtsilä hybrid propulsion system with methanol engine to power four SAL heavy lift vessels; wind farm installations

Green Car Congress

Wärtsilä’s hybrid system will feature a variable-speed Wärtsilä 32 main engine capable of operating with methanol fuel. They will also be the first methanol capable ships to employ a variable speed main engine in a hybrid installation.

New silicon-hydrogel composite Li-ion anode material shows long cycle life, easy manufacturability

Green Car Congress

The hydrogel is polymerized in situ , resulting in a well-connected 3D network structure of Si nanoparticles (SiNP) coated by the conducting polymer. A g -1 , the composite electrode exhibited a relatively stable reversible lithium capacity of 1,600 mAh g -1 for 1,000 deep cycles based on the weight of only Si. Click to enlarge.

Winter 2011-2012: Engine Bay and Under-car: The car is now completely gas-less. No engine, no fuel tank, no alternator, pumps, radiators, exhaust pipes, or muffler. For tachometer, I will be using a sensor ring on the second shaft end of the motor connected to a new instrument.

most deep cycle batts. If I were a better engineer, or designer I could have planned for a standard length of these connectors. I placed 4 in the front compartment and the other 16 in the bed. The technical problems that I encountered were in figuring out how to mount the tie downs for the batteries. in the end.

These electrode assemblies are then sandwiched together with conventional separators and positive electrodes to make the battery, which is filled with an acid electrolyte, sealed and connected in series to the other cells. Sustain 80-85% round trip efficiency in PSOC applications; 90-95% in deep cycle applications. PbC battery.

Proud of its roots

I ordered a controller from a company in California, which used a single power Darlington transistor, and 4 deep cycle 12-volt batteries.” “I cut the frame and extended it, and then a guy from the DEVC donated a golf cart motor,” he explained. “I So I took it upon myself to help keep its memory alive.

The promise of wireless charging: smaller batteries, longer battery life, fewer charging stations

Charged EVs

We connect high-power communication lines into the DC charging system of the car. Overnight or deep-cycle discharge damages batteries, and high C rates degrade batteries because of the temperature created. times more life expectancy for a battery versus a deep-cycle charging approach. How does that work?
