DBM Energy - New Test Appears to Back Range Claim for New Battery

Makers of batteries for plug-in vehicles are in something of a tight spot. They are under considerable pressure to improve their products so that electric vehicles will be attractive to more drivers. But if they actually manage to come up with a radically improved battery, their breakthrough is likely to be met with skepticism perhaps dealing a permanent blow to their reputation.

Which brings us to DBM Energy, Lekker Energie and their converted Audi A2, powered by a Kolibri battery, which according to DBM traveled 375 miles without a recharge last fall. If such exceptional range didn't inspire skepticism on its own, the fact that the A2 test car was subsequently destroyed in a warehouse Hp pavilion dv7 batteryfire (while sparing the battery used in the test) surely did the trick.

The inspection organization Dekra has done independent tests for DBM and, once again, the pack seems as good as promised. In a press release, DBM said Dekra tested a 63 kilowatt-hour Kolibri battery, which uses lithium-metal-polymer battery cells, in an A2 on a chassis dynamometer. It found that the car was capable of traveling 455 kilometers, about 283 miles, on a single charge.

This may seem too good to be true especially given some claims that the pack will cost thousands of dollars less than those from other battery companies but the miles-per-kilowatt-hour rating is not that out of line with packs that are on the road today in the Tesla Roadster.

Tesla's lithium-ion hp nc8430 battery Acer as07b31 batterypack has a capacity of 56 kilowatt-hours and has an official range of 245 miles. That works out to be 4.38 miles per kilowatt-hour. The Kolibri offers 4.49 miles per kilowatt-hour. This alone doesn't prove that the Kolibri works as advertised, but suggests that it's not as outrageous as some make it out to be.

DBM also subjected some of the Kolibri's cells to safety tests, this time conducted in January by the German Federal Institute for Materials Research and Testing, known as BAM. After the eight tests were completed, BAM said the cells "easily passed the entire range of tests" and confirmed that the Kolibri is safe enough to use in passenger and commercial vehicles.

The latest test results should help DBM move forward with the full-scale field trial planned for this year. The results may also stoke the fires of skepticism, but what else is new?
