Our car battery is one of the last things you could think of becoming smart, but there are some folks out there who want to make this happen. And what’s there to make smarter, right? Well, what about the fact that your car battery dies without warning, leaving you stranded, and that it’s quite heavy, not to mention the ecological threat that they pose.
Ohm is a startup which wants to change that, being lighter and smarter. While most automotive batteries weigh around 40 pounds, Ohm thinks it can become a smarter care battery with a weight of just 6 pounds. This is made possible thanks to a more advanced technology than just lead plates – an EDLC supercapacitor capable of dumping enough energy to start your engine, and a set of smaller batteries free of toxic heavy metals.
Furthermore, Ohm is smart enough to keep you from accidentally draining your battery if you forget to turn your lights off. The device will automatically turn itself off when it gets critically low, and then switch itself back on when you go to start your car. Another great feature is that Ohm copes much better with cold temperatures than lead-acid or lithium-ion batteries.
If you have a car, you are probably aware that lead-acid batteries last three years on average; well, Ohm promises that its battery will last more than twice that period. Of course, this is going to be reflected in its price, as well, which is expected to be around $200. But since you’re getting a longer lifespan and all the other benefits, it isn’t actually that expensive, after all. Here are its main specs:
- 550+ CCA (Cold Cranking Amps)
- 7 year average lifetime
- Rated for -30°C to +50°C
- Weighs 6 pounds
- 10 Amp hour reserve capacity
- Group 35 form factor
- Never needs jump-starting
- Reactive architecture
- LiFePO4 battery chemistry
- EDLC supercapacitor chemistry
- Dimensions: 9.0″x6.8″x6.8″
At the moment Ohm is in private beta testing, with only dozen units out in the wild but the company plans to roll out a crowdfunding campaign in the near future, so we will keep you updated as to when that happens.
