Practical aspects of off-grid EV charging

Charged EVs

The most common choices of battery type are lithium iron phosphate (aka LFP or LiFePO 4 ), all of the other lithium-ion chemistries (including recycled batteries from junked EVs), and, finally, lead-acid.

False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

Photo-illustration: Max-o-matic; photo source: M&N/Alamy Some operators of early direct-current power plants at the turn of the 20th century solved the problem of uneven power output from their generators by employing large banks of rechargeable lead-acid batteries, which served as a kind of buffer to balance the flow of electrons.

The GWKulla, a short, curvy compact, runs on lithium-ion batteries and can go 160 kilometers (99 miles) when fully charged, the company says. Great Wall Motor Co., Its expected price tag is between 60,000 yuan and 70,000 yuan, or about $8,780 to $10,250. BYD has said it is aware of these issues and is working resolve them.

A closer look at minimizing AC charging losses: From the breaker to EV (Part 1)

Charged EVs

Any competent electrician should be able to size the wire for a Level 2 EVSE in a manner which complies with code, but mere compliance is not necessarily ideal here, particularly if the EVSE or outlet is far away from the breaker, as any losses in the wiring are directly added to the cost of recharging the EV battery.

Electric Car Manufacturers Inspire New Paradigms -- Seeking Alpha

Tony Karrer Delicious EVdriven

The MiEV runs on a lithium-ion battery pack that can be charged in seven or so hours on a 240-volt line. Today we could be using lead-acid EVs, lead-carbon-acid EVs, or nickel metal hydride or lithium-ion hybrids. Then I recall that my laptop batteries barely ever last four years.

at least, the recycling infrastructure for the well-established lead-acid batteries is robust. lead-acid batteries have a far better recycling rate than even aluminum bottles — over 90% of lead-acid batteries are recycled. None of the new electric cars are planning to use old-tech lead acid batteries.
