This TechLetter will focus on WATTALPS battery thermal modeling and the explanation of WATTALPS patented cooling architecture advantage. To illustrate this, we will show simulation results on a sportscar application, for which cell thermal stress can be compared to a...
This TechLetter will focus on the thermal management of batteries. Indeed, battery performance and life are greatly affected by the temperature of the cells. It is therefore important to control cell temperature to ensure a good productivity of an electric equipment...
This TechLetter aims at presenting in a simple and didactic way the complex topic of functional safety assessment and its application to batteries. This topic is covered by several standards, most of which are derived from ISO 61508. We will here focus on 2 standards:...
In this new TechLetter, we will focus on the case study of a battery in a fuel cell system. In an hydrogen vehicle, the fuel cell produces electricity to power the electric motor by consuming hydrogen as a fuel. There are numerous fuel cell technologies but we will...
This TechLetter will focus on the Battery Management System (BMS) and all associated functions. WATTALPS has developed internally its Full BMS solution adapted for demanding mobile applications, mastering the specification, the hardware design, the software...
