Safety

When discussing any vehicle, safety is definitely one of the most important topics. But when discussing an electric vehicle, safety is almost an even bigger topic than that of a combustion engine. First, let's get one fact straight -- anytime you are traveling with a large amount of stored energy i.e. hydrogen, gasoline, or electricity, there will always be a danger. Now from type to type, the dangers can vary, but there will always be a danger with any of those kinds of vehicles, and there has been for a couple hundred years. 

Lithium batteries, thanks to a few spontaneous fires, a couple Samsung cell phones on fire, put lithium batteries under a cloud of caution. Lithium is great for many reasons, but it can also be very dangerous if not treated with respect and caution.

We build our new battery modules out of 1/4 inch Lexan, which is a bulletproof polycarbonate. The 1/4 inch thick material is rated to stop a .22 caliber bullet. While this may seem overkill for our modules, it is important to go overkill in regard to safety. The thick bulletproof box is then assembled with small countersunk stainless steel screws all around the module to create an ultra strong construction. These very tough modules are also mounted to the car through thick steel brackets underneath, securing the modules to the car completely in the case of an accident.

There is also a special switched called an inertia switch implemented in all vehicles. In the case of an accident, on the instant moment of impact this switch shuts down the whole electric vehicle to prevent any kind of runaway event. This was tested in my unfortunate accident with my Electric Celica, upon the instant of being hit, my inertia switch completely shut my car down and prevented any further injury or issues. This is an affordable add on to the electric vehicles that make puts an additional level of important safety on the car.
