By heating the battery pack to a temperature above freezing, it permits the battery to simply accept a full amperage cost with none danger. Moreover, as a optimistic facet impact, it leads to a heat cabin whereas the battery heats up, including to passenger consolation throughout chilly days.
The Price Issue It’s essential to notice that preconditioning does eat electrical energy, and this price is borne by the EV proprietor. Whereas none of this power goes immediately into charging the battery, the advantages of preconditioning largely outweigh this minor price.
Actual-World Proof from a Tesla Mannequin Y Proprietor To grasp the real-world influence of battery preconditioning, a Tesla proprietor carried out a check together with his Mannequin Y in chilly climate, documenting it on the It is Solely Electrical YouTube channel. The check concerned charging the EV at a V3 Supercharger underneath two completely different situations: with and with out battery preconditioning.
Within the first situation, with a preconditioned battery at a ten% state of cost and an exterior temperature of 30° F (-1° C), the battery accepted a cost price of as much as 238 kW, finishing the charging session from 10% to 80% in 33 minutes. This was barely longer than regular because of the chilly climate however nonetheless environment friendly.
Conversely, when the battery wasn’t preconditioned, the charging session took 42 minutes for a similar cost enhance, virtually 10 minutes longer. Furthermore, the cost price peaked at solely 135 kW, considerably decrease than with the preconditioned battery.
Preconditioning is Key The conclusion drawn from this check is evident: preconditioning your EV’s battery in winter is crucial for an environment friendly and fast charging session, in addition to for sustaining the well being of your battery.
