Just talking about electric cars, there is a common question about what will happen to electric car batteries, if they decrease in capacity, or if there is an accident or damage. Will the electric batteries be thrown away? Earlier this year, BMW Malaysia announced a collaboration with the University of Malaya in reusing electric car batteries and they have shared a little about the project.
This collaboration with the University of Malaya involves three institutions, namely the Power & Advanced Energy Centre (UMPEDAC), the Community Engagement Centre (UMCares) and the Sustainable Development Centre (UMSDC). This is because it also involves a program with the Semai Orang Asli community in Ulu Sendirut, Kuala Lipis, Pahang. Through it, this community will receive battery packs that can provide electricity for storing fresh food and meat so that it remains safe for a long time.
In the picture above, it is an example of how the 3rd Generation lithium battery installed in a BMW electric car. This used battery unit is seen to be able to provide energy to the refrigerator, which can ensure their food supply lasts even though it is small in size. This battery will be connected to a solar panel for the purpose of recharging during the day.
Another use of this used battery pack is as a device charger at the University of Malaya bus stop. With the combination of a solar roof, it can charge this used battery pack, which can then be used by students while waiting at the stop. In the picture above is a prototype charger with a used battery pack from BMW which is used to charge smartphones and laptops at the same time.
With the latest partnership on sustainable projects from BMW Malaysia and the University of Malaya, this somewhat provides exposure on the cycle of electric car battery packs which have various uses even though they are no longer used for cars. BMW Malaysia also emphasized that the used battery packs for the purpose of this collaboration will remain recorded (Battery passport) to ensure that they are recycled in a responsible manner, not as easy as just throwing them away.
