EV Battery Testing
A one-stop solution for all you need in battery testing
The market for electric vehicles (EV) is growing rapidly due to factors such as supportive government policies and regulations promoting the adoption of EVs, increasing investments by leading automotive OEMs, rising environmental concerns regarding automotive emissions, and the decreasing prices of batteries.
The fast growth of EV industry has led to an expanding demands and production of batteries used in electric vehicles. This includes raw materials, components and battery cells/modules/packs in the entire manufacturing chain. Therefore, an intensive and comprehensive testing is necessary to improve reliability, safety and performance of EV battery.
Read on to find out our EV battery solution for your needs:
Mechanical stress is a very important parameter in the automotive industry due to the dynamic movement of wheels, and uneven road surfaces that the vehicle may interact with.
Therefore, a battery system must be able to handle these vigorous vibrations for long periods of time. Vehicle collisions are also a crucial threat and any battery system that experiences such an event must be able to either survive or break graciously.
In general, the mechanical test of EV battery includes shock, drop, penetration, vibration, immersion, crash, rollover tests.
Electrical abusive tests to evaluate the electrical safety of the battery include external short circuit or short circuit protection test, internal short circuit test and overcharge/over-discharge protection tests.
From life cycle testing to driving simulation, our state-of-the-art testing equipment covers the laboratory testing and manufacturing of cell, module, and pack for electric vehicles.
The additional applications include but not limited to charge/discharge, cold crank, reserve capacity, start/stop, supercap/ultracap testing.
Environmental testing aims at evaluating the safety performance of a battery system under extreme conditions like temperature change, such as an accident scenario involving fire, or extreme weather exposure in certain geographic areas.
The most common environmental tests for batteries are thermal stability, thermal shock, overheat and extreme cold temperature and fire tests.
Our test chambers achieve EUCAR hazard level 6 which covers safety test to all major standards.
Lithium-ion batteries contain significant amounts of potentially hazardous materials like highly flammable electrolytes, corrosive, and toxic components. If exposed to certain conditions, the integrity of the battery is compromised which may lead to electrolyte leakage, venting, rupture or even fire and explosion.
The amounts of gas released from various cells during a thermal runaway event must be measured. The gases being released are composed of a mixture of species, such as carbon monoxide, carbon dioxide, methane, hydrogen, oxygen, ethane, ethylene, hydrofluoric acid. The exposure of persons in the vicinity of such compromised batteries can lead to serious injuries.
Thus, it is of significant to identify and quantify substances being released from the battery during tests representing misuse and abuse events and to ensure that the amounts released are not hazardous to vehicle occupants and first aid responders.
