Lithium-ion (Li-ion) batteries have been used in consumer electronics for more than a decade. In that time, the capacity and durability of these batteries has increased dramatically. Case in point the 20kWh battery module inside the Fit EV.
Compared to most other Li-ion batteries currently in use, the Fit EV battery can be charged quicker, has twice the number of charge cycles and can operate in a much wider temperature range.
OPERATING FIT EVs IN HOT OR COLD CONDITIONS
The available driving range for the Fit EV may be significantly reduced when the vehicle is operated in hot or cold conditions, due to some battery capacity loss and increased use of air conditioning and heating. This is particularly true with cold temperature operation. Batteries work by chemical reaction, and the speed of the reactions decrease as the temperature drops, resulting in a temporary decrease in total battery capacity. Driving range is further reduced by increased heater and other accessory use. In extreme cases, some Fit EV drivers have reported driving range reductions of 50% or more in cold weather. In hot weather, drivers have reported range reductions of 10% or more. As the hot or cold temperatures abate, these reductions in driving range should abate as well.
The Fit EV's cabin is heated by an electrical coolant heater, which warms the cabin quickly but uses a lot of power in the process. The heater, and all other accessories, draws power from the car's high voltage battery unless the car is plugged into a Level 2 (240V) charging system. Reducing accessory drain will improve overall driving range.
