Quelles sont les tendances les plus prometteuses en matière de véhicules électriques et hybrides ?

One of the most challenging aspects of electric and hybrid vehicles is the battery design, which affects the performance, cost, safety, and environmental impact of the vehicles. In my experience, the key factors to consider in battery design are the energy density, power density, cycle life, thermal management, and recyclability of the battery materials and components.

Dentro do meu campo de conhecimento, o maior desafio das baterias para o carro híbrido ou elétrico é o desempenho da bateria. Com o desempenho atual, as baterias ainda são muito grandes, consomem muito espaço no automóvel e pesam bastante. Consequentemente, a quantidade de minérios utilizados é maior, aumentando assim o seu custo. Apenas com o avanço de novas tecnologias de baterias que tenham um desempenho maior, será possível eliminar este gargalo. Ora, basta compararmos com gadgets que, constantemente precisam ser recarregados. Por enquanto, o mundo continua na dúvida se o carro elétrico ou híbrido é a solução para a descarbonização do mundo, oferecendo o custo beneficio ao consumidor.

Lucid is the one to examine when it comes to powertrain and battery EV efficiency. There is simply no match when it comes to power per weight. Their experience in racing has also given them an edge when it comes to batteries. Peter Rawlinson (CEO) has done an excellent job explaining their approach to the motors and inverters in the Lucid Tech Talks found on LinkedIn and YouTube.

I remember when I first learned about regenerative braking, I was fascinated by the idea of recovering the energy that would otherwise be wasted as heat. However, I also learned that regenerative braking is not a perfect system, and it has some limitations and challenges. For instance, regenerative braking cannot provide enough braking force in some situations, such as emergency braking or low-speed braking, and it requires a conventional friction braking system as a backup. Moreover, regenerative braking can affect the vehicle dynamics and stability, and it requires a sophisticated control system to coordinate the regenerative and friction braking forces.

Quando pensamos em carros elétricos e, isso inclui o híbrido, pensamos nos custos: preço do carro, consumo de combustível, seguro do carro entre outros. Esquecemos que o objetivo maior é a descarbonização do planeta. diminuindo ou eliminando os combustíveis fósseis em automóveis. Porém, esses altos custos são absorvidos atualmente pelo cliente final. Sim, este que se dispõe a pagar muito mais caro no carro elétrico e todo o ecossistema que implica em sua compra. Ainda precisa considerar instalar o carregador em sua residência. Vale a pena?

Electric and hybrid vehicles are not only vehicles, but also part of a larger system that includes the energy sources, the charging infrastructure, the mobility patterns, and the user preferences. Therefore, to design and optimize electric and hybrid vehicles, we need to consider not only the vehicle characteristics, but also the system characteristics, such as the availability and cost of electricity, the location and capacity of charging stations, the driving behavior and demand, and the user satisfaction and acceptance. Furthermore, we need to consider the environmental and social impacts of electric and hybrid vehicles, such as the life cycle emissions, resource consumption, noise, and air quality, and public health and safety.
