特徴

自動車用として最適なパフォーマンスを持つAESCのリチウムイオンバッテリー

AESC's pouch type of Lithium ion battery can easily achive higher energy density in both of volume and weight. A unique "flat shape" of battery also contributes to increase surface area of a battery and thus is also good for simplfying thermal management system to keep battery temperature at good condition too. As a result, lithium-ion batteries from AESC exhibit high energy density and advanced performances, can be easily installed to vehicle, and are also the optimum battery in terms of cost.

AESC cell has an unique structure in which cathode coated with Li transition metal oxide on an aluminum foil and anode coated with a carbon material on a copper foil are alternately stacked with a separator. The stacked is sandwiched with 2 laminated sheets and then sealed well to keep air tighness.
The features include a large surface area, a sheet-like shape, and a simple structure, and because of these features, the cells demonstrate good heat dissipation and allow for a high degree of freedom in the design of the battery shape to accommodate loading the batteries into a vehicle. AESC's batteries also demonstrate the high performance that is needed for automotive use while remaining low in cost.

EV用とHEV用の違いとは

AESC produces batteries for electric vehicles (EV) and batteries for hybrid electric vehicles (HEV). Both are types of lithium-ion batteries, but because battery requirements differ for EV and HEV applications, the materials, structures, and performance also differ.
The batteries for EV use are designed as high capacity type batteries in order to extend the distance that can be driven on a single charge, while HEV batteries are designed as high output type batteries that can instantaneously transfer a large amount of power.

Electric vehicles are powered only by the energy that is stored in the on-board batteries. Therefore, EV batteries must be designed as large capacity batteries so that vehicles can travel long distances on a single charge. In addition, sometimes electric vehicles must be charged away from home, so the batteries must be capable of being charged with a fast charger.
The capacity of AESC's lithium-ion battery cell for EV is about 15 to 30 times larger that of a typical smartphone.

高出力を可能にしたAESCのHEV用リチウムイオンバッテリー

高出力を可能にしたAESCのHEV用リチウムイオンバッテリー

Hybrid electric vehicles (HEVs) have the propulsion system by the combination of Internal Combussion Engine (ICE) and Electric Motor. Battery and Motor operate to assist ICE, for example, in case that vehicle needs a large torque at the time to start moving itself. And during decelertion or going downhill, driving energy is recovered and charged to battery. Therefore, AESC's Lithium-ion battery for HEV applications is especially designed to achieve high power perfomances.
