Resource Reference: Electric Car Charging Point Map Stats-Driven Guide
Globally, The number of publicly accessible chargers reached 1.8 million, an increase of 37% in 2021. Whereas, in the UK specifically, there are over 27.5k charging devices in the UK. Since 2015, public charging devices have grown by 43% year-on-year. This growth is only going faster. In fact, the government has set ambitious targets of introducing 145k new charging points every year from 2030 onwards. However, not all charging points are created equal.
In the UK, 56.7% of EV charging points are classed as fast, meaning they’ll fully charge a Tesla Model S in 5-11 hours. In October 2021, EVs held a 23.1% market share of all vehicles being registered in the UK — this is a sharp rise from April 2021, when it was just 13.3%. 22% of British drivers state that they are very likely to switch to electric vehicles in the future.
Their other key findings include:
- The rise in EV charging points in the UK
- How fast different charging points will charge your car
- The popularity of electric vehicles
- Consumer attitudes towards EVs
And now, with that in mind, let’s back to our business of the day…
What Is A Battery Management System?
Simply put, Battery Management System is the brains behind battery packs. They manage the output, charging, and discharging and provide notifications on the status of the battery pack. They also provide critical safeguards to protect the batteries from damage. Let’s take a look at a battery management system to familiarize ourselves with its components.
The single most important function that a battery management system performs is cell protection. Lithium-ion battery cells have two critical design issues; if you overcharge them you can damage them and cause overheating. And even explosion or flame so it’s important to have a battery management system to provide overvoltage protection.
In addition, Lithium-ion cells can also be damaged if they’re discharged below a certain threshold, approximately 5 percent of total capacity. If the cells are discharged below this threshold their capacity can become permanently reduced.
All in all, to ensure a battery’s charge doesn’t go above or below its limits, a battery management system has a safeguard device called a dedicated Lithium-ion protector. Every battery protection circuit has two electronic switches called “MOSFETs.” MOSFETs are semiconductors used to switch electronic signals on or off in a circuit.
What A Discharge MOSFET And A Charge MOSFET Entails
A battery management system typically has a Discharge MOSFET and a Charge MOSFET. If the protector detects that the voltage across the cells exceeds a certain limit, it will discontinue the charge by opening the Charge MOSFET chip. Once the charge has gone back down to a safe level then the switch will close again.
Similarly, when a cell drains to a certain voltage, the protector will cut off the discharge by opening the Discharge MOSFET. The second most important function performed by a battery management system is energy management. A good example of energy management is your laptop battery’s power meter. Most laptops today are not only able to tell certain aspects.

Considerably, such as how much charge is left in the battery but also what your rate of consumption is and how much time you’ll have left to use the device before the battery needs to be recharged. So, in practical terms, energy management is very important in portable electronic devices. But, wait a moment… What does a Battery Pack contain?
Usually, a battery pack consists of several individual cells working together. If they go out of balance, there’s stress on individual cells. Leading to premature charge termination and a reduction in the overall battery cycle life. The battery management system — battery cell balancers — extends its life by preventing this imbalance of charge in individual cells from occurring.
The Key Battery Management System Features Plus Notable Vehicles
By definition, the key to energy management is “Coulomb Counting.” For example, if you have 5 people in a room and 2 people leave you’re left with three if three more people enter you now have 6 people in the room. If the room has a capacity of 10 people, with 6 people inside it’s 60% full. A battery management system tracks this capacity.
This state of charge is communicated to the user electronically through a digital bus called an SM BUS or through a state of charge display where you press a button and an LED display gives you an indication of the total charge in 20% increments. Battery management systems for certain applications also include an embedded charger consisting of a control device.
A good example is such as the one for this hand-held point-of-sales terminal shown in the illustration image above. Not forgetting, an inductor (which is an energy storage device), and a discharger. After all, the control device manages the charging algorithm. For lithium-ion cells, the ideal charging algorithm is constantly current and constant voltage.
1. Battery-Powered Electric Vehicles (BEVs)
To enumerate, Battery Electric Vehicles (BEVs), or as frequently called EVs, are fully-electric vehicles with rechargeable batteries and no gasoline engine. Battery electric vehicles store electricity onboard with high-capacity battery packs. Surprisingly, BEVs do not emit any harmful emissions and hazards caused by traditional gasoline-powered vehicles.
A recent study shows that in the first half of 2022, the number of new battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs) reached 4.3 million. Electric Vehicle (EV) chargers are classified according to the speed with which they recharge an EVs battery. For your information, the classifications are Level 1, Level 2, and Level 3 or DC fast charging.
Level 1 EV charging uses a standard household (120v) outlet to plug into the electric vehicle and takes over 8 hours to charge an EV for approximately 75-80 miles.
Important to realize, level 1 chargers (workplace/home-based) have the capability to charge most EVs on the market. While level 2 charging requires a specialized station that provides power at 240v. Then again, level 2 chargers are typically found at workplaces and public charging stations. And will take about 4 hours to charge a battery to 75-80 miles of range.
Level 3 charging, DC fast charging, or simply fast charging is currently the fastest charging solution in the EV market. As of today, there are quite a number of various BEVs plus manufacturer examples that can charge on DC Level 3 Fast Chargers. Below is a list of the topmost manufacturers of battery electric vehicles in the industry.

2. Plug-in Hybrid Electric Vehicle (PHEV)
A Plug-in Hybrid Electric Vehicle or a PHEV like Chevy Volt can recharge the battery through both regenerative braking and “plugging in” to an external source of electrical power. While “standard” hybrids can (at low speed) go about 1-2 miles before the gasoline engine turns on, PHEV models can go anywhere from 10-40 miles before their gas engines provide assistance.
Below Are Other PHEV Examples

3. Hybrid Electric Vehicles (HEVs)
On one hand, HEVs are powered by both gasoline and electricity. The electric energy is generated by the car’s own braking system to recharge the battery. In general terms, this is what most professional electricians will call ‘regenerative braking.’ Bear in mind, that regenerative braking is a process where the electric motor helps to slow the vehicle.
And while doing so, it uses some of the energy normally converted to heat by the brakes. On the other hand, HEVs start off using the electric motor, then the gasoline engine cuts in as load or speed rises. Some of the most common Hybrid Electric Vehicles (HEVs) include Toyota Prius Hybrid, Honda Civic Hybrid, Toyota Camry Hybrid, etc.
Eventually, it’s extremely simple to charge your electric vehicle at an EVgo station. There are 3 different ways to charge your car quickly and easily. For example, you can use an app, your RFID card, or a credit card. Learn everything about charging an Electric Vehicle in detail. Including how to charge, charging time, charging cost, and driving range on a single charge.

So far, it’s important to realize, that only BEVs are capable of charging on a level 3, DC fast charge. Before you go for the likes of Orion BMS Lithium-Ion Battery Management System, there are some key functions of the Battery Management System you need to know about. In general, the battery management system should achieve the following functions:
A. Accurate SOC Estimation
As an example, estimate accurately the State of Charge (SOC) of the power battery pack. That is, the remaining battery power. In reality, ensuring that SOC is maintained within a reasonable range, prevents damage to the battery itself due to overcharging or over-discharge. Remarkably, displaying the power energy remaining in the hybrid electric vehicle battery at any time. Of course, referring to the charging state of the energy storage battery.
B. Dynamic Battery Monitoring
In the process of battery charging and discharging, the terminal voltage and temperature of each battery, charging and discharging current and total voltage of the battery pack are collected in real-time to prevent overcharging or over-discharging. At the same time, it also can show the status of batteries, select the batteries with problems, maintain the reliability and efficiency of the whole battery operation, and make the realization of the residual power estimation model possible.
C. No Overcharging/Over-Discharging
By the same token, the charging and discharging process of batteries usually utilizes current sensors. In particular, with higher accuracy and better stability for real-time detection. Generally, according to the different front-end currents of BMS, the corresponding sensor ranges are chosen to approach.
D. Quality Balance Among Batteries
