Same is the case with the batteries that are used to power Electric cars. Such cars have very long charging time, for instance, a minimal charge takes 30 minutes or more. And when you actually wish to move, it would need that charge.
One company has made the first breakthrough by inventing a Lithium Polymer battery that puts every other battery manufacturer to shame. DBM Energy has been manufacturing batteries that allow forklift trucks to operate in warehouses for 28 hours between charges. Their latest creation is called KOLIBRI, which has been deployed into a car and the results are pretty amazing.
The battery was put to test using standard Audi A2, a battery operated Electric car. With everything stock except for the battery, the car was set to benchmark the battery power.
With approx. 6 minutes of charge, the car traveled whooping 375 miles (600km) over a journey of seven hours averaging speeds of 55mph. On finishing the drive, CEO of DBM offered to recharge the phones of the reporters as it still had some juice left. 6 min charge time for 100 kWh – it is important to know with what kind of a fast charger it was done, but in anyway – if battery can sustain 2500 cycles with this kind of fast charger – it is another breakthrough. Question will in Charging Infrastructure, but it is 6 min for 100 kWh – too good to be true for a Lithium Metal Polymer!
The drive is now called Munich-Berlin project, with which DBM wanted to know if its batteries would work for road cars rather than just forklifts, and without a doubt it looks promising for almost everything from trucks to cars.
Comparison with Other batteries : Over 300 Wh/kg – to put it in perspective – Nissan Leaf 24 kWh battery will be less than 80 kg! We have heard that Renault Fluence 24 kWh battery weight is 240 kg.
One final piece of good news about this battery is DBM believes it can manufacture it cheaper than the other lithium ion batteries being developed. That means the premium for an electric car using a DBM battery solution should be lower than the competition.
Welcome to the future where Short Charges, Extended Battery life has become a reality. DBM seem to have solved both problems with wide range of battery options of batteries that charge insanely fast, and batteries that last really long.
This car is definitely was not optimized for optimal battery performance, if in future lighter cars are made, the efficiency could be even better.
375 miles for a 5 minute charge is something that anyone would beg for, making it to be more than enough for most journeys.
So when exactly are we getting these in EVs? It would take sometime till some car manufacturer holds the deal with DBM and puts these powerhouse into commercial cars. Going green would now be more easier.
