Tend to agree - there absolutely should be at least an option to buy batteries, for those that wish to, but unfortunately, that’s clearly not what they have in mind at this point in time. Gogoro’s profit model looks to be based, overwhelmingly, on a battery subscription service, a variant of the old razor and razor blades model, or printer and print cartridges scheme. I think it’d be unwise to force this on the public. It might eventually be undone or worked around via aftermarket products, but I fundamentally agree - people should have options, not limitations: buy with or without batteries, plug-in, lease, etc…
Their estimated 95 km range, if riding aggressively, will likely be <60 km. Few will be content for very long with going out of their way to visit a battery station after every ~55 km of riding, four times as frequently as they did for petrol.
For these reasons, it’s wise to be sending out a rather clear message now, on Facebook, in forums, in comment sections on articles, etc, that in the aftermath of their CES debut and before they engage in the next phase of this multi-million dollar effort, digging in the trench of a limited battery option is not settling so well with the entire market. This is happening to some degree in online chatter now, but I would not sit back and let it play out. Startups hear these voices, or allow themselves to hear them, when they’re wise. The knock on effect, even if they do not alter their plan, is that others have heard and seen the needs to be met in the market, and another Gogoro comes up to meet them, sooner.
On Batteries…
HH, Abacus, and others have alluded to the difficulties and risks in owning batteries, so I’d like to point out a few notes about battery tech. Smaller, highly portable batteries are, by nature, not going to provide the additional capacity to avoid damage and a shortened lifespan. In a sense, the way to deal with potential battery degradation will seem quite counterintuitive to those who do not work with batteries at this level, but it is the approach that Tesla takes. Their design factors for battery degradation by supplying considerably more of the Panasonic 18650 cells than are actually required to travel a target distance or achieve a certain impressive performance level. Why? Laptops and smartphones, which for many of you is likely your nearest point of reference for lithium batteries which you’re extrapolating to EVs, are designed for portability and cost. The implications are not just on the size and form factor of the battery, but on its life expectancy as a result of such devices being taxed to run between 0% charge and 100% charge, as people push the daily usage life to its limits.
With properly designed power management systems for EVs, however, this is not done. An EV’s battery is too valuable as a percentage of the total vehicle cost. It is not dropped below ~20% state of charge, nor taken to a full 100%. The software in the Model S or Roadster may indicate zero, or 100%, but it is neither. It’s 100% of what you may give and 100% of what you may take, but there is excess at either end. Prius batteries can go for 200,000 miles, and some Teslas may reach similarly impressive heights, primarily because they are designed and over built with enough capacity to fulfill their duty without suffering from what we typically do with smartphones and laptops, items which aren’t intended to have a useful life beyond 4 years anyway, as people wish to upgrade. So you can work out the implications of this on small portable batteries are. If you want small and manageable, you don’t get an 8 year life, as it would be necessary to increase capacity (size and weight) by ~40%.
Because of Gogoro’s constraints on battery size due to portability needs, their modules will likely be somewhere in between a proper integrated EV battery design and a laptop or smartphone’s, probably skewed towards the latter, as it offers immediate performance in a tolerably-sized small form at less initial cost. In contrast, an integrated high-performance battery would take up all of the battery module space and the helmet space beneath the seat, but properly managed by software, provide a much longer useful life. Helmet and cargo could be stored in an add-on unit on the back, a common item for scooters. I would wire it so one could use a standard Gogoro battery module in the cargo bin if ever in an emergency. The ability to plug in anywhere is certainly a benefit in such situations, and an emergency battery delivery service, as an ancillary industry, could be developed. Between the plug, the removable battery, swap kiosks, home charging of batteries, the option to own or lease your own, plug-and-park stalls at apartments, in other public areas, business plug-and-park options, and battery support services by other providers…the range of options to support smart-scooters is diverse, and we’ll need a combination of them. They shouldn’t be so severely limited by design.
