Recent battery management system advances are increasingly proving that the key to cost-effective energy storage might not be what you use… but how you use it.
Last year, for example, Energy Storage Report unveiled news of a French start-up called Enerstone, which is commercialising an active battery management system that can extend the lifespan of batteries by up to 30%.
The system monitors the health of each cell and redistributes loads so that “weaker ones work less than stronger ones, to extend the battery life to the benefit of the user,” explained Enerstone’s president and co-founder Alexander Chureau.
This month, meanwhile, a senior executive at Greensmith unveiled that its energy storage management systems had made it possible for lithium-ion batteries to beat lead-acid not just on performance but also on cost.
In one particular project, “the deployment of lithium-ion was half the price of lead-acid over the lifetime of the system, and it’s entirely due to software,” Leesa Lee, senior vice president, product management and marketing, told Energy Storage Report.
