Problems solved by technology
[0005] In some other applications, specifically in cold climates, since the temperature of the battery pack can drop below a certain temperature, the battery will tend to lose desired levels of performance and may negatively affect battery life cycle
For example, in some batteries, low temperatures can cause the electrolyte to freeze, which can further lead to damage to the battery case
Also, at low temperatures, a certain chemical reaction may lead to a reduction in current generation and thus a loss of available energy

A battery charging apparatus includes a battery compartment having a receptacle that is configured to receive a battery pack. The battery charging apparatus includes a first heat exchange module and / or a second heat exchange module. The first heat exchange module includes a plenum surrounding the receptacle, where the plenum includes a chamber to receive a fluid. The plenum also includes a plurality of flow guides disposed in the chamber to define a variable flow passage for the fluid. The second heat exchange module includes a battery connector and a heat sink thermally coupled to the batteryconnector. The heat sink is arranged to dissipate thermal energy from the battery pack.
Description
technical field [0001] The present disclosure relates to a portable electrical energy storage device, such as those powered devices that require power (such as automobiles, consumer electronics, and other powered devices), and heat exchange systems and methods that facilitate portable electrical energy storage Dissipate heat from the device, or provide thermal energy to a portable electrical energy storage device during or prior to charging. Background technique [0002] Batteries such as lithium-ion batteries are known to store more energy in smaller and lighter cells. Lithium-ion batteries have been widely used to power portable electrical energy storage devices such as mobile phones, tablet computers, notebook computers, power tools and other high-current devices. Low weight and high energy density also make lithium-ion batteries more attractive for use in hybrid and electric vehicles. [0003] In some applications, multiple individual Li-ion cells are packaged together...
