What Is C-rate? How to read battery discharge curves?
The C-rate is a measure used to describe the rate at which a battery is charged or discharged relative to its capacity. It is expressed as a multiple of the battery''s capacity. For example, a discharge at 1C means that the battery''s entire capacity is discharged in 1 hour, while a discharge at 0.5C means
What really matters is the average charging rate and how long it takes to add real-world miles. We test from a 10 to 90 percent state of charge on the fastest equipment an EV can handle.
When, at a charge voltage of 2.45 ± 0.05 volts/cell, the current accepted by the battery drops to less than 0.01 x C amps (1% of rated capacity), the battery is fully charged and the charger should be disconnected or …

Everything you always wanted to know about fast charging
The BMS instructs the fast charger to set the charge speed. This speed is usually expressed in kilowatt (kW). Charging a car for 1 hour at 50 kW puts 50 kWh of energy into the battery pack. On average, an electric vehicle uses 1 kWh to drive 5 km. Some vehicles, like Tesla, also express the charge speed in kilometres of range gained per hour ...
In the charge curve below you can see the charge speed of the Ampera-e. On average the Ampera-e charges 100 km of range in 20 - 25 minutes. The Ampera-e charges fastest until about 55%.
AGM Battery Charing | How to charge an AGM battery
The total charge time thru stage 2 should not take longer than 10-12 hours. If this time is exceeded, charging should be stopped, and the battery, charger and/or charge process should be analyzed. The maximum time in hours should = 1.2 times the Depth of Discharge (DOD) in Amp-hours (AH) divided by the average charge current in amps.

The average C-rate when charging from 20% to 80% SOC is 1.1C. *C-rate tells us how the charging power relates to the battery pack capacity. For example: 1C is 1-hour charging power (current), when ...
We''ve given you the basics of understanding your charging curve but not all electric cars are created equal – each model has its own charging curve and time it takes to charge. This means that if you have two cars that claim the same charging capability (e.g. 150kW) and you plug them into one of our High Power chargers, you …
