How Does the Tesla Powerwall work ?

A  Powerwall system consists of at least one Powerwall battery and a Backup Gateway. The Backup Gateway provides energy management, metering and monitoring functions for Powerwall. It controls connection to the grid, safely disconnecting your home and starting backup operation during an outage. The Backup Gateway also includes communication functions for up to 10 Powerwall units, and receives over-the-air updates for the system.

Lithium Ion battery (Li-Ion)

A Lithium Ion (Li-Ion) battery is a rechargeable battery with twice the energy capacity of a Nickel-Cadmium battery and greater stability and safety. LiIon batteries use a liquid lithium-based material for one of their electrodes.

Lithium Ion batteries are often compared to LiPo (lithium polymer) batteries. True LiPo batteries aren’t commercially available due to poor room-temperature performance. What is referred to as LiPo in commercial use is really a LiIon-polymer hybrid or a standard liquid electrolyte in a polymerized foil pouch format. Pouch-formatted LiIon liquid batteries still require hard casing in the product to prevent expansion that would otherwise become a performance and safety issue.

There have been incidents of combustion or explosion in LiIon batteries in high-drain applications such as hoverboard and portable vaporizers. One cause may be the proliferation of low-quality and even counterfeit LiIon batteries. The LiIon cells used in the Tesla S high-performance electric car are based on safer new technologies, allowing for discharge down to zero volts without incident.

The best battery choice really depends on the particular application. LiIon have better low-temperature discharge performance, with operating ranges of -20’C-60’C. Some can suffer from aging, however, even when not in use. Although care must be exercised in sourcing the batteries, LiIon is better suited to very high-drain devices. Both LiPo and LiIon batteries require special smart chargers and often require  circuit protection for safest use.
