Depending on the situation, the batteries can be temperature controlled in three different ways: 1. If the outside temperature is low enough, passive cooling is possible. The system "uses" the slightly lower outside temperature for energy-saving battery cooling.

The primary components of a battery pack are the battery modules. The battery modules contain the lithium-ion cells and are usually designed in such a way that their module terminal voltage is below 60 V, and hence they can be handled without additional and expensive safety precautions (see Section 10.2.1).).

Like many electric vehicles, the BMW i3 uses a system of indirect liquid cooling in order to achieve safe cooling on the battery pack. These cooling systems are, in many ways, quite similar to those used in an internal combustion engine vehicle, using a series of metal pipes to circulate coolant that transfers heat away from the battery pack.
To avoid undesirable effects of thermal behaviour, high-voltage batteries are equipped with extensive temperature management and cooling systems to ensure operation in the optimum temperature range. In addition, it is thought to achieve an even temperature distribution within the battery as well as insulation against external influences.
Understanding the system architecture—is it low or high voltage and is it an AC or DC system—that will be worked with is important to ensuring safety as well. Alternating current (AC) and direct current (DC) are the two methods used for current flow in electronics.
