Titolo: BYD B-Box il competitore In Cina del Tesla PowerWall


 
Un anno fa la BYD introduce il B-Box Battery Energy Storage Systems
per il mercato australiano.
 
Esiste un due "sapori":
- B-Box LV Residential
- B-Box LV Professional
 
Questi sono le tante agognate LiFePO4:
 
"They are based on the company’s proprietary Lithium Iron-Phosphate
(LiFePO4) storage chemistry, which has an outstanding safety record
and makes it the ideal technology for countries like Australia."
 
Un po' dati:
 
"The B-Box HV Series employs a modular design with battery capacities
ranging from 5.6 to 10.08 kWh, providing more than enough energy for
the average household and can be scaled up to 50kWh for commercial and
industrial applications. The B-Box LV Residential Series is available
in four capacities ranging from 2.5 to 10.0 kWh and can be scaled up
to 80kWh."
 
La taglia di 5,6 a 10,08 kW*h (decimi di kW*h ?) indica un
prodotto nel settore delle PowerWall, almeno come "ordine di
grandezza".
 
Piu' avanti, citano anche taglie minori:
 
"The B-Box modular design concept provides flexibility to meet
customer needs with initial investments in systems as small as
2.5kWh in capacity. The modular design and smart battery
management system allow convenient extendibility to increase
power capacity during throughout the product’s lifetime."
 
Ecco il massimo raggiungibile per le due versioni:
 
"When multiple boxes are connected in parallel, the B-Box LV
Residential 10.0 reaches a maximum capacity of 80 kWh, whereas
the B-Box LV Professional 12.8 can reach a maximum capacity of
409 kWh, providing more than enough power for an energy-intensive
medium-size business. The modular design also allows for easy
installation and uninterruptable maintenance."
 
 
La BYD rispecchia la stessa ragione della Tesla:
 
"The B-Box uses the same high-output, completely recyclable,
long-lasting lithium iron phosphate (Li-FePO4 or LFP) battery
chemistry and control technology that has safely powered
BYD’s electric vehicles for more than seven years, meeting
stringent automotive and railway application standards for
safety, including TUV, UL and RCM. With 10-year warranty
protection, the highly efficient air-cooled B-Box provides
a whole new solution to both residential and commercial users."
 
Cioe' la batteria nella B-Box deriva da quella usata nel
settore veicolare.


 
"The Newcastle-based sales and distribution manager at Solar
Australia has over the past eight weeks sold more than
300 "B-Boxes", the newly released power storage unit from
China's BYD, the world's largest producer of rechargeable
batteries."
 
Ovviamente il tono va preso con beneficio di inventario.
 
Un richiamo a chi c'e' (anche) dietro:
 
"The little known BYD, which counts Warren Buffett as a
shareholder, is making a big push into Australia this year,
targeting NSW residents no longer receiving generous
feed-in-tariffs for solar power."
 
Attenzione "little know" non implica che BYD sia "piccola".
 
Chen avrebbe puntato a 4000-5000 vendite nel 2017,
di cui 2000-2500 fuori dalla Cina.
 
Riguardo all'andamento dei prezzi:
 
"BYD, which is also the world's largest producer of electric
vehicles, forecasts the price of home battery packs to fall
a further 30 per cent over the next three years, but Ms Chen
does not believe the declines will be as large as those for
solar panels."
 
"I think prices will fall over the next three years then be
pretty stable after that," she said noting that raw material
prices were a major impediment to further price falls."
 
 
A proposito di "retroattivita'":
 
"It is estimated 140,000 NSW residents lost their 60¢ per
kilowatt hour feed-in-tariff towards the end of last year
and now receive around 6¢ per kilowatt hour for selling
solar power into the grid."
 
Gli anglosassoni, quando sbagliano rettificano l'errore,
non accettano che un ingiustificato guadagno conseguenza
di errori di valutazione del legislatore.
 
 
Vediamo come sono le LiFePO4 dal punto di vista dei
prezzi:
 
"He said BYD's previous home battery offering, known as
the Mini, cost around $11,000 for 6 kilowatt hours of
storage capacity, while the B-Box was priced at $8500 for
a 10 kilowatt system. That's a 53 per cent decline per
kilowatt hour of storage between the first and second
generation systems."
 
 
Sono $8500 per 10 kW*h, decisamente piu' caro della
offerta Tesla.
 
Mi ero dimenticato nel precedente intervento: anche
la BYD offre dieci anni di garanzia.
