Find out about a new battery for electric vehicles - 10 times the power of lead acid
storage | news | transportDetails of a new energy-storage technology are slowly being released by Texas startup
EEStor. While electric motors and hybrid vehicle technology have improved at a huge rate during recent years,
battery technology has remained static with weight, low energy storage, and cost being the main bottleneck in electric car development.
EEStor's alternative to current
lead acid and
lithium-ion battery technology is a parallel plate
ultracapacitor using barium-titanate powders. EEStor claim that the new technology can store 10 times more power pound for pound than lead-acid batteries while costing half as much and without needing toxic chemicals.
According to the latest information available, full charge can be achieved in minutes rather than hours since overheating is not an issue (unlike existing battery technology), and hundreds of thounsands of recharge cycles are possible without performance falling. According to EEStor a 17kWh system could be charged in just 4-6 minutes. A 400lb 52kWh electrical storage unit (ESU) will eventually be marketed at $3,200 with prices falling to $2,100 with volume production.
The first commercial application of the EEStor energy storage system will be the
ZENN electric car (pictured above) manufactured by Canadian
Feel Good Cars. ZENN are expecting delivery of the systems this year. The 15kWh electrical energy storage units (EESU) will recharge in minutes, weight under 45kg, and will operate in -20 to 65 degree Celcius ambient temperatures.
