Honda e and e:Ny1


To some drivers, the latest electric cars may seem like a mobile laboratory, crammed with technology and offering a dazzling glimpse of motoring’s bright future. Yet in some ways, electric cars are remarkably straightforward, featuring battery technology which is simpler than cars with petrol or diesel engines.


How big is an electric car’s battery?

Like the variety of cars they power, the batteries in electric vehicles vary in size. They’re often packed away under the floor, taking up all the area beneath where everyone sits. Some will be rectangular shaped, others may resemble a ‘T’ section when viewed from overhead. And the larger they are, the heavier they will be.

In the new Honda e, the battery is beneath the middle of the car’s floor and it powers an electric motor that is located under the boot floor.

How does an electric car’s battery work?

The modern battery in an electric car is lithium-ion. Inside the cell, positively charged lithium ions are carried by a liquid electrolyte from the anode to the cathode through a separator. This movement results in the discharge of an electrical current. And that electricity is used to power the motor or motors that drive either two or all four wheels.

Maintaining the battery

The greatest potential convenience about an electric car is that it can be charged whenever and wherever it is parked. This saves drivers from going out of their way to find a charging station. The power will be drawn from the grid. That means the sustainability will vary according to the energy provider. At home, the battery is best charged using a dedicated ‘wallbox’. The wallbox typically delivers a charging rate of 6.6kW, which means a car like the Honda e, which has a 35.5kWh battery, would be charged from low warning to 100 per cent in around 4.1 hours. Using a more powerful 50kW rapid charger at a public location, the Honda e’s battery would go to 80 per cent charge in just 31 minutes.*

*Charge times are measured from the low battery warning indicator.

The Honda e's battery

Designed from the ground up, the Honda e is the first Honda to be built on a purpose-designed platform for electric vehicles. The stylish electric car features a water-cooled 35.5kWh lithium-ion battery that can be charged using either Type 2 AC connection or a CCS2 DC rapid charge.

The Honda e will be capable of travelling up to 137 miles before drivers will need to recharge the battery. To ensure the Honda e has a responsive feel on the road, engineers have centred the battery low in the platform, giving the compact car perfect 50:50 weight distribution and an excellent centre of gravity.
