EV Charging Solutions: Seal and Protect in an Electric Vehicle
The success of any electric or hybrid/electric vehicle (EV/HEV) relies on how well it stores energy and how quickly it recharges. Once the effective vehicle range of a single charge compares with a quick fill up at the gas pump, consumers are more likely to make the transition to an electric vehicle. OEMs are at the forefront of pioneering innovations in EV charging solutions, aiming to enhance battery capacity, efficiency, and lifespan, while also minimizing charging times making EVs and HEVs more attractive to consumers. Any industry-changing innovation is not without its challenges; vehicles are limited on space, weight, and power, and must meet demanding cost and reliability requirements (SWAP-CR). Vehicles are subject to harsh environmental constraints, which can pose difficult environmental sealing and protection requirements for large electronic systems and batteries.

Maximize electric vehicle efficiency with Boyd’s comprehensive EV charging solutions. The effectiveness of an electric vehicle hinges on its battery, a key factor determining the effective range the vehicle has on a single charge. Batteries store DC power in between charges for the rest of the vehicle’s electronic systems to consume during operation. An EV’s battery pack is typically constructed from a series of battery cells consisting of lithium-ion (Li-ion or Li-ion cells), either in the form of small cylinders or flat rectangular pouches. Alternative technologies like fuel cells are also options in power storage for electric and hybrid vehicles. The battery powers the entire vehicle and has a significant weight and space allocation, which OEMs strive to optimize and improve with each design iteration. Smaller and lighter weight batteries enable designers to incorporate higher powered or more densely packed battery cells for greater range. Partnering with Boyd’s design and engineering team enables you to develop optimized solutions that protect your battery from environmental conditions and improve power storage performance and efficiency. We create integrated solutions using highly engineered materials like SOLIMIDE ® Foams, Heat Shields, and battery gaskets to make your battery enclosures safe and reliable. Boyd’s integrated solutions enable you to better protect passengers and improve the overall safety of your electric vehicle.
充电站和电动汽车维修设备
充电站和电动汽车服务设备（EVSE）通过促进从电网到电动汽车的电力传输，在改变电动汽车充电解决方案方面发挥着至关重要的作用。它们构成了充电基础设施的支柱，推动了电动汽车充电技术的发展和普及。
充电器有不同的级别，反映了功耗和充电速度：
1 级：为电池充电过夜的典型家用充电器
2 级：一些家用充电器需要几个小时才能充满电池电量
3级：增压器
更高级别的充电器需要更多功率，从而缩短充电时间，在 10-12 分钟内提供 100 公里行驶距离这一重要里程碑。eMobility 行业正在转向需要更高电压的快速充电，以与传统内燃机 （IIC） 加油时间周期竞争。
Some chargers have the capability to convert AC power from the grid into a DC current and voltage that will safely charge the electric vehicle battery. These types of chargers use an electrical inverter, a series of electrical switches that rapidly alternate to transform the AC current to a DC current. These inverters may also include step down converters or buck converters to bring high DC voltages to the preferred battery voltage. Most of these chargers are installed in an outdoor environment and subject to external weather conditions. High power electronics within charger systems must be protected from rain, UV, wind contaminant, and other damages making charger enclosure systems, seals, and protection solutions critical to ensure longer and reliable product lifetimes.

The On Board Charger (OBC) of an electric or hybrid vehicle converts AC power from the grid provided by the charging station into DC power that charges the battery. Batteries store energy as DC, so the more power that an OBC unit can handle and convert efficiently, the faster the battery can safely charge. The On Board Charger utilizes a series of semiconductor devices to convert AC current into DC. These semiconductor devices switch rapidly and produce large amounts of waste heat in the process. On Board Chargers might include a step down converter, buck converter or 3-phase Input Power Factor Correction (PFC) components in addition to the main inverter to decrease high DC voltages to lower battery voltages for safer storage.
