Enjoy optimum EV performance, and optimum driving comfort too

Preconditioning is a very useful way of enabling your battery to perform more efficiently and safely.  

Preconditioning typically involves the automatic heating or cooling of the battery to bring it within a moderate temperature range where it can perform under optimal charging conditions. 

So even in the heat of a blistering hot summer or the depths of a frozen frosty winter, preconditioning can make your drive smoother, help maximize your battery’s range management, and prolong its life.  
 

How does it work? 

Your EV has a dedicated thermal management system (TMS), which is constantly working out the most efficient way of performing (whether you’re driving or not!). So, if the TMS detects that your battery is becoming overheated, or too cold, it can adjust the battery’s environment accordingly so it performs at the optimum performance level. 

It can also prepare your battery for a charge if you’ve included a bp pulse charging break in your journey’s navigation. It will then work out which of our chargers you’re using, and set the optimum battery temperature to receive charge from that charger. 

Your TMS can even set your cabin temperature too. It’s a very luxurious feeling to climb into a cosy warm car on a frosty morning! 

 

Benefits of preconditioning 
 

Prolongs battery life Batteries perform better and longer within a moderate controlled environment 

Faster charging time 
Adjusts the battery’s environment depending on which charger is being used.  

Longer range An excessively hot or cold battery can lead to a reduction in range.  

Extreme weather management 
Warm your battery in cold weather, or cool it in hot weather, to perform better.  

 

How to use preconditioning  

Most EVs have automatic TMS preconditioning technology, which will activate seamlessly to maximize the efficiency of your journeys. It may be possible to change the parameters and settings that your TMS uses; if so, these parameters should be in the vehicle settings you access from your EV cabin.  

If you have an app for your EV, then it may be possible to manually activate, adjust, or switch off preconditioning settings. 

Of course, different EV models tend to have slight variations, so refer to your vehicle manual for all the details. 

 

Common myths about preconditioning 

You may have heard differing opinions on when or even whether to use preconditioning. Here, we explain away the most popular misapprehensions about this process. 

 

Preconditioning is only for extreme weather 

While preconditioning is most critical in extreme weather (especially when it’s very cold), even in moderate temperatures it can still enhance charging speed and battery life. 

 
All EVs have the same preconditioning 

Not all EVs are equipped with the same preconditioning capabilities. Some models benefit from highly sophisticated Thermal Management Systems, while others may have simpler systems or lack automated preconditioning. Check your vehicle manual or a dealer to make sure.

Preconditioning always saves on charging time 

Preconditioning can reduce charging times; but it doesn't always make a noticeable difference unless compared with a battery that is at an extreme temperature. In moderate temperatures, the effect on charging time may be minimal. 

Enjoy your EV driving more with preconditioning 

Preconditioning is an extremely beneficial function for enjoying optimum battery performance when charging and driving; so use it!  

And remember as always, whenever you need a top up, the bp pulse charging network is here to keep you going. Why not download our app now, so you’ll always know where your nearest bp pulse charger is, wherever you are in the UK.
