Regenerative and Disc Braking used to stop the EV: Controlled through the Electronic Differential Motor Controller(EDMC): EV004:

Regenerative and Disc Braking

Regenerative Braking starts in some EVs when the driver eases off the Gas pedal. But kicks in when the Brake pedal is applied, and the drive motors go in reverse. The last stage requires the disc brakes to halt the Vehicle.

Checking Designs

Brake control system designs are checked using Matlab and Simulink design analysis tools. Service data will take time to collect and confirm the benefits. Mechanics doing servicing on EVs will notice the difference in the wear on the Disc Brakes.

Motors & Generators on each Wheel: The Electronic Differential Motor Controller controls a motor controller on each wheel: EV002:

 

Motors & Generators on each Wheel

Normal Setup:

To ensure the correct response from the driver using the Steering Wheel and the Gas pedal. To enable relating to vehicles with engines. Drivers will notice the difference between two and four wheel driving.

Adding Generators:

A generator on each wheel to charge the on-board Battery and extend the range of the EV.

With Battery status detected to switch off the Generators, until the Battery is down to 40%.

Charging Data:

Data collected to set the recharging level for the type of Battery versus usage.

Drive and Brake Pedals are like an Automatic: Reversing with one pedal control: Brake Pedal combined with Park to stop EVs: EV005:

Drive and Brake Pedals

Automatic Driving

This will change, but should not take drivers long to adjust. The EV pedals will be like an Automatic. Both Pedals use resolver modules to adjust the voltage to the Motors.

Reversing:

Pressing a button on the Steering wheel reverses the Motors. The EDMC controls the Motor Vehicle speed from 0 to 5 mph. The e-Pedal as explained in the Nissan article allows one pedal control of the EVs movement.

Learning:

Need more EV drivers to enable collecting data on using one pedal. Most drivers will be able to adjust their driving. Practice will make reversing easy. The Brake pedal used if needed and combined with Park and the signal sent to the EDMC.

EDMC, motor controllers and components on Electric Vehicles benefit from airplane and train technologies: EV003:

 

Electronic Differential Motor Controller

The Steering Wheel

Sets direction of travel as straight, left, or right using a geared variable resistor. 

The EDMC

Takes inputs and provides outputs. To each of the controllers driving the rear wheel motors or motors on all four wheels. Matlab and Simulink Design Analysis Tools:

Motor and control system technology designs checked using Matlab and Simulink.  

Design Data:

Appears each year, but more EVs on the road required for data analysis. 

Users Will Give Feedback:

Once they feel comfortable driving EVs and trade press coverage will confirm experiences.

Change:

Drivers will notice how quiet EVs run.

Mains Charging: 2nd contractor switches in 10 ms: Earth leakage trips Residual Circuit Breaker limit in on-board charger: Electric Vehicle 006:

 

Soft Start and Inrush Limited Battery Charging

The First Contractor

Connects the mains to the single phase/three phase transformer. With anti-surge supplied by two

resistors in parallel on the Live and Neutral power lines. Mounted across the second contractor

that switches in after 10ms. With peak energy at 14.5kW. The peak energy defines the power

selection of the resistors.

 

In-rush Power Protection

Supplied by the Residual Circuit Current Breaker. It trips when Earth leakage exceeds the set figure.

Allows time for the Transformer impedance to settle when using the on-board charger.

Physical Size

Both the power source and on-board charger. Being limited by technology. It is moving fast and in

3 to 5 years will be the size of a paperback book.
