Electrovaya battery passed the UL 2580 drop test with flying colors. The battery weighing over 3000 lbs was subject to drop from a height of 1m at an angle likely to produce the most adverse effect. The battery not only survived the impact of the fall, it was completely operational following minor repairs to the pass-thru and bus-bar system – a testament of great engineering design.

The UL 2580 Drop Test
The test was conducted at room ambient (i.e. 25 +/- 5°C). Temperatures were monitored on an internal module casing during the test for information purposes.
After being equilibrated at room temperature, a fully charged sample of Electrovaya Battery weighing over 3000 lbs was dropped from a height of 1.0 m. The sample drop was designed to strike a concrete surface at an angle in the position most likely to produce the adverse results and in a manner and height most representatives of what would occur during maintenance and handling/removal of the battery during servicing.
During the test, a spark ignition source or a gas detector was used for determination of potential for fire hazard. This is done to detect the presence of flammable concentrations of gases within the sample immediately after the drop and repeated in the instance of increasing temperatures.
The sample was examined within a time frame of 6-24 hours after dropping. After the 6-24 h rest period and after cooling to near ambient, the samples were subjected to an “as received” isolation resistance test in accordance with UL 2580-ULC S2580.
Result
The sample remained intact and operational after minor repairs to pass-thru and bus-bar assembly. After the drop, the sample was subject to a full discharge and charge cycle. The sample retained full operationality and there was no internal damage to the battery and battery management systems.
