Electrical vehicles comprising of cars, buses, and two-wheelers, offer a noiseless and comfortable ride.  These vehicles carry rechargeable batteries that power the electric motors responsible for the propulsion.  Performances of these batteries are defined by how long and how far they can propel the vehicle before running out of charge.  The motors are far quicker than a conventional combustion engine in achieving the desired rotation and allows for a better acceleration of the vehicle.   During braking, the motor feeds back the energy to the battery.  Partly due to lesser conversion mechanics, and partly due to regenerative braking, electrical vehicles are far more efficient than their gas counterparts.

Electrical Batteries

EVs rely on energy from large and powerful Lithium-ion batteries.  The type of the battery is the same as that found in a typical smart phone.  While phone batteries contain a few cells, EV batteries are made out of 5000+ cells lined together to add up to hundreds of volts and amperes.  This results in effective battery capacities of 100kWh for cars and 300kWh for buses.  Such large capacities can power sports cars that clock 0 to 100 kph in less than 2 seconds and haul eighteen-ton buses up to 600 km on a single charge.  Because of their unstable nature, Li-ion batteries need a computer-controlled Battery Management System (BMS) to ensure operational stability. 

Charging Stations

The “e-fuel” for the EV is obtained through charging stations.  The stations have charging cables with Type 2 Plugs made in accordance with the IEC 62196 standard.  The vehicle carries the corresponding socket.  Drivers can leave their vehicle plugged in to top up the batteries in around an hour thanks to fast charging technology. These stations come with pay-per-charge schemes and are spread across major towns in most countries. 

Connectors within the battery

Amphenol ICC’s high power connectors like PwrBlade+® and SheerPwr Circular interface the circuit boards of the BMS computer to the battery unit.  Wire-to-Board and Board-to-Board Connectors like 1.25mm pitch Wire-to-Board and 2.54mm pitch BergStik® Header are part of circuit boards that form an essential part of a BMS.  Vehicle data recorders can use high speed networking to read the signals from the BMS through HSBridge Connector System

With electric vehicles reported to be safer than their internal engine counterparts, investing into this market means we can deliver a cleaner, safer, and promising future in mobility.
