Electric vehicle battery technology is moving forward rapidly, but the fundamental principles of battery performance clash with the fundamental expectations of consumers: give me high energy density but charge quickly. Raising the rate of charging leads to higher temperatures across the battery cells. The effect of high temperatures means that battery performance will degrade over such cycles, which has been termed aging by industry.
Optimizing battery charge rates and coolant flow rates becomes an engineering imperative, but the charge controller and coolant controller must also prevent rapid aging. Fortunately, the ThermoAnalytics battery extension provides an accurate simulation of battery temperatures over time during both charge and utilization, enabling engineers to balance convenience with aging. In the consumer EV market, the fast charge wins the sale, but it’s avoiding aging that builds customer loyalty.
