Battery Charge and Warning Symbols
After a Volvo symbols update, our EV, Hybrid and Plug-in Hybrid Battery Charge and Warning Symbols page now holds 14 images! And it is hardly the most prolific page! This is primarily because the automotive industry lacks discipline — or someone to apply that discipline — and continues the absurdity that is automotive dashboard symbols, telltales and indicators. Our pages now hold well over 1,000 distinct versions!
The Volvo update added two black and white versions (right), bringing the total to six of the 14. We certainly feel obligated to include them, as a driver needs to know that they are looking at exactly what they see on their instrument panel in order to feel confident about the information being given to them.
And note that the second symbol with the padlock is said to be an indicator that the hybrid battery is holding its charge! Isn’t that what its supposed to do??
Despite calls for uniformity and promises of such, auto manufacturers continue to forge their own paths when designing indicators. The addition of information displays on instrument panels has prompted the new assortment of black and white entries. Fortunately, this usually — but not always — include a text message explaining what the indicator is trying to tell the driver.
We’re pretty comfortable saying that oftentimes these messages are less than helpful.

This and the images that follow below are Hybrid EV Mode Indicator 
The same basic image as above with a line drawn through it indicates that EV mode is not available, again because the proper conditions are not met. It may also mean that a destination may have been chosen in navigation that exceeds the hybrid battery range.
The text only symbol, eDRIVE, is found in hybrid systems that switch between using the internal combustion engine, the high voltage battery, or a combination of both automatically when conditions warrant. It will be displayed when the vehicle is under battery power alone.
This text only symbol, eBoost, will be displayed when a hybrid vehicle is under extreme acceleration, such as in passing situations. It indicates that the high voltage battery is in full use to support or Boost the acceleration.
This symbol, also in black and white features a drawing of an internal combustion (IC) engine with an embedded circular arrow. It indicates that the hybrid vehicle is operating on the IC engine alone.
This image indicates that use of the high voltage battery is on hold. The vehicle will operate using the IC engine predominantly in order to maintain the charge level in the high voltage battery. It too is in black and white.
These two are related as they both indicate that hybrid operation is in automatic mode. The second adds a slightly misshapen triangle underneath which indicates that the navigation system is active and that navigation data is being taken into consideration.
This set of indicators come from Honda Motors Corp. found in their Hybrid vehicles: Auto Mode, Charge Mode, and EV mode. In Auto Mode, the vehicle selects which propulsion source is most appropriate, the electric motor, the gasoline engine, or a combination of the two and automatically switches to it. In Charge Mode, the engine starts and the High Voltage battery charges. In EV mode, the vehicle is propelled exclusively by the electric motor, so long as the battery has sufficient charge. And to the extent of battery charge, these modes can be chosen at will by the driver.
These final three images are associated with what is termed a Mild Hybrid System, which uses a smaller, 48-volt battery to assist the driveline. The first image is displayed when the battery is supplying power. The second indicates that the battery is supporting high acceleration. The third image indicates that power from the mild hybrid system is unavailable.
This is a Hybrid Operation Indicator 
These are the Recuperative or Regenerative Brake System (
The two additional version to the left are Regenerative Braking Icon Indicator 
These also appear as household batteries, but as Max Regeneration indicators, they are meant to indicate that maximum regeneration capability has been engaged and operating. They will be accompanied by the following instrument cluster messages: Max Regeneration On when the feature is turned on, Max Regeneration Off when the feature is turned off, and Max Regeneration Unavailable when the feature is requested, disabled.
These indicators come from another manufacturer, Kia, which uses arrows and the colors 
This is a Regeneration Boost Indicator 
Similarly, Honda Motors Corp. offers the option the increase or decrease the rate of regeneration using a paddle on the steering wheel stalk. The result is the symbol to the left, a Deceleration Paddle Selector Indicator. Using the deceleration paddle selector, the driver can you sequentially shift through six stages of deceleration. The more larger V shapes are seen, the more deceleration is chosen. The M indicates that the choice has been locked in, suggesting the letter should be an L!
The symbols to the right are also used as Regenerative Brake System Indicators.
Its got to be the plug. Its about the plug!
A friend passed along a New York Times article titled Should I Get a Hybrid or Go Full Electric? The title is linked. After reading it, and combined with additional information that was already running around my head, I emailed him back remarking that its all about the plug!
Two hybrids
The article explains the two types of hybrids: conventional and plug-in. Conventional hybrids have a battery that powers an electric motor to augment the gasoline engine. It also incorrectly seems to suggest that energy from braking alone charges the battery, when in fact the gasoline engine charges the battery continuously.
A plug-in hybrid has a larger battery that can powering car solely with electricity for short distances, on average 40 to 50 miles. And they can be charged using the same Level 1 or Level 2 chargers that EVs use. High power Level 3 charging is off the table, which the article misses.
But this is not intended as a critique of the article…
So, back to the point. The battery in a plug-in hybrid will be charged by the gasoline engine if its power is drained, operating exactly as a conventional hybrid.
Imagine you are the owner of a plug-in hybrid. Theoretically, if you drive less than the battery’s range, you can go indefinitely with using any gasoline. What’s needed now is a convenient place to plug in, and the willingness to, in effect, manage an EV!
Further, in the scenario described, a plug-in hybrid needs to be plugged in daily. A full EV only needs a charge maybe once or twice a week!
This is what was rummaging through my mind. The European auto market is down, way down, and only one segment one segment is up, albeit slightly. And its the conventional hybrid market.
Its all about the plug!
Plugging in is the change. As a people, we’ve grown accustomed to driving and stopping randomly for a fill-up. The plug is the change of religion. Everything else is essentially the same: a steering wheel, accelerator pedal, brake pedal, and on and on and on.
The last hurdle will ultimately be more places to actually use the plug!
Heck, even EVs have warning lights. Lots of them. See our page here.
