Electrification is the future. The switch from internal combustion engines to electric vehicles (EVs) is accelerating, powered by advancements in technology, environmental awareness, and consumer behavioral changes. The rise of the EV will bring about a broad reset of customer expectations, a flood of new original equipment manufacturer (OEM) designs, and many new engineering needs.
Highly engineered, innovative solutions to meet the needs of the EV era. From materials to mechanical solutions, we are ready to support our customers in the EV industry.
Batteries can be protected from shock in two ways – potting materials and mechanical isolation. To protect cells from shock using a potting material, a liquid is dispensed around the battery cells, which then cures to a soft solid, damping vibration that would be transferred to the cells and preventing or significantly reducing their movement from shock. To protect cells from shock using mechanical isolation, the battery pack can be attached to the rest of the vehicle using elastomer-based mounts that will absorb and damp any vibration that would be transferred to the battery pack. Potting materials and mechanical isolation can be used in conjunction with each other for extra shock and vibration protection.
Currently, lithium-ion (Li-ion) batteries are the most common in electric vehicles. Every all-electric vehicle contains a battery pack approximately the size of a queen-sized mattress at the bottom of the vehicle that contains hundreds to thousands of individual Li-ion cells, depending upon the geometry of the cells – cylindrical, prismatic, or pouch. All-electric vehicles use these batteries primarily because of their high-power density, which ultimately allows for the vehicles to have longer driving ranges. Other electric vehicles, like plug-in hybrids (PHEVs) or hybrids (HEVs) also typically use Li-ion batteries, though some use nickel-metal-hydride (NiMH) batteries. NiMH batteries are typically less expensive and perform better in extreme temperatures, but they also are less power-dense than Li-ion cells and cannot charge or discharge as rapidly as Li-ion cells.
